Comparison of Telemarketing, Direct Selling, KA and Channel Agents | SaaS Entrepreneurship Roadmap (71)

Author introduction-Wu Hao, SaaS strategy and marketing consultant, Tencent SaaS accelerator tutor, author of a series of articles; Angel investor and former CEO who enjoys selling customers. A series of books of the same name will be published in February 2020.

Many of my articles were chatted with SaaS founders or team leaders. Perhaps this is the vitality of these words.

Since it is still the planning season, this article still has to continue to talk about annual planning.

This article comes from talking with a sales person in charge one day about how to divide regions and allocate resources among various sales teams in the company. I’ll throw out the results of the discussion first, and then make a detailed breakdown.

A few days ago, when communicating with a well-known SaaS enterprise executive team, I was still saying that I like the telemarketing team best, not emotional love, but from the perspective of CEO+CFO.

The cost of reaching customers by telemarketing is low, and it is much easier to cultivate communication skills than direct selling (face-to-face communication). Telemarketing is where dozens of people sit together, and on-site management is much easier than field management of direct sales representatives.

The bigger advantage is that when we need to expand the market coverage, we just need to add seats in the office or rent the office next to it. There is no need to send general managers and executives to open branches in another city, and there is no need to take risks to let a new branch manager take on all business and management responsibilities in a newly opened city.

The total operating cost of telemarketing is also relatively low, there is no travel expenses, and the labor cost is generally lower than that of direct selling.

Therefore, from the perspective of CEO and CFO, telemarketing is the first choice for SaaS companies. Most American SaaS companies I know are like this.

The best partner of telemarketing is "market clue". If the company has a certain brand, can bring natural traffic, and the clues brought by SEM can cover most of the clue needs of the telemarketing team, then the combination of "market clues+telemarketing" will be invincible.

In the past two years, I have seen the average monthly output of some sales representatives of the telemarketing team reach 80,000, and some reach 120,000 (the customer unit price is not high, and there are many odd numbers). It can be calculated that the gross profit of their sales team is very good.

Even if there are insufficient market clues, it is faster to find clues through telemarketing than through ground forces.

Of course, electricity sales also have three limitations:

◆ The customer unit price cannot be high.

◆ Product configuration and operation should not be too complicated.

◆ Customers don’t need to change the business process when using this product (the implementation is not difficult).

In addition, in the output results, there are still problems of insufficient regional market coverage and insufficient penetration.

In a word, telemarketing is "fast replication, wide coverage, shallow penetration and high gross profit".

The direct selling team, like the telemarketing team, has the opportunity to become an iron army with high combat effectiveness.

Direct sales representatives need to go out to visit customers, which makes their sales skills, understanding of product value and understanding of customer business more demanding. The data I saw with my own eyes, even if it is the same product and the same level of clues, the price of direct sales will be much higher than that of electricity sales.

However, due to the characteristics of "on-site visit and departure management", the management difficulty of direct selling team is more than twice as high as that of telemarketing team. Even an excellent manager, the efficiency of departure management can not exceed that of the telemarketing team manager. The number of direct sales teams reaching target customers and obtaining effective business opportunities every day is weaker than that of telemarketing teams.

Therefore, it can be seen that if a direct sales team is established, it must be different in product prices to ensure that the direct sales team can sign a larger list.

The direct selling team is not slow to replicate locally. However, if you want to use the direct sales team to cover a larger area, you will face the problem of difficult management of business trips.

What if more branches are opened? It will also face the problem that branch managers are not easy to cultivate.

Although some excellent enterprise service companies can solve these problems well, it will take a long time: it will take at least one year to successfully complete the layout of branches in four first-tier cities, from talent reserve training to branch opening, recruitment, training and optimization.

The sales leads of direct selling may come from market leads, or from the self-development of sales representatives and the referral of their own customers. Because the direct selling team can meet customers and have deeper offline interaction with customers, it has more advantages in self-development than electric sales. Therefore, direct selling can make a regional market deeper.

From the practice of domestic SaaS companies, in the cost structure of direct selling teams, the marketing rate (the sum of sales and market expenses ÷ sales revenue) is mostly between 60% and 90%. Therefore, the cost is relatively high, and the gross profit of new customers in the first year is not very good.

To sum up briefly, the characteristics of the direct selling team are: "fast replication, less coverage, deep penetration and low gross profit".

Let’s make a simple division, and call the fast one-sided sales team with a unit price of 10,000 ~ 80,000 customers "direct sales team"; The "KA team" is the sales team whose customer unit price is more than 80,000 yuan and needs to provide solutions to customers.

Compared with direct selling, KA has higher requirements for sales representatives’ product ability, solution ability and ability to understand customers’ business.

As you can imagine, according to such requirements, the speed of KA team training talents is limited, and it also takes a long time to dig people from outside the company and integrate them into the company’s organization and culture. The management complexity of KA team is less than that of direct selling team. KA management is more driven by values and performance goals, and its process management complexity is not as high as that of direct selling teams. KA process management focuses more on business-side capabilities such as sorting orders.

Regarding the degree of dependence on market clues, the KA team has two extremes. What I see is usually that the KA team of universal tool SaaS relies heavily on market clues; However, the sales representatives of big customers in SaaS companies often gain the trust and business opportunities of big customers through their own mixed industry circles.

Getting a KA account often involves many roles such as pre-sales, service, product research and development, and the per capita annual output far exceeds that of the direct selling team, so the marketing rate of KA team is often not high, and the company’s Mao Lijiao is good.

Summarize the characteristics of KA team: "slow replication, large customers, deep penetration and high gross profit".

These characteristics will affect the salary performance design of telemarketing, direct selling and KA teams. How to design specifically, please see my related article: (67) Annual Salary and Incentive Design #SaaS Entrepreneurship Roadmap #

My agent here does not include a System Integrator who can do customized development and system integration for big customers, but only refers to a relatively pure sales agent.

Should SaaS companies build agency channels? I have an article devoted to it. Interested readers can read it: SaaS entrepreneurship roadmap (54) Discussion on channel value.

This article only discusses the way of channel agency, which is different from direct sales and electricity sales for SaaS companies.

Channel construction is a long process. If SaaS companies want to build a channel department, they must have a long-term investment plan.

It is not easy to convince a large number of agents at the beginning. It is necessary to invest heavily in supporting several high-quality agents and set the benchmark. The work of channel management is also relatively complicated, and the talents in the channel department are relatively hard to find.

From the perspective of sales leads, agents should have the ability of self-open source. If they mainly rely on the leads provided by manufacturers, the efficiency may not be as good as that of Saas company’s electricity sales or direct sales. The purpose of cooperating with agents in second-and third-tier cities is to dig deep into the regional market, so agents should have the ability to penetrate the local market.

In the design of channel system, service problems are often considered. The agent is a very suitable service subject in the local area. The customer success department of SaaS company should coordinate the national customer service and renewal rate targets, and agents can’t get something for nothing, and they can get corresponding returns by contributing to the service and renewal.

In the second, third and fourth tier cities, although labor is much cheaper than direct selling teams, its transaction efficiency is often not as good as direct selling. At present, the proportion of new single share and renewal share distributed by most SaaS companies to agents is not low (generally between 50% and 70%), and the gross profit margin of channel agency is relatively low when the cost of channel department itself is included.

Summarize the characteristics of the channel agent team: "Replication is slow first and then fast, with deep penetration and low gross profit".

After talking about the characteristics and limitations of each team, we can also talk about how these teams are matched for different products and markets.

Combination a, electricity sales+direct sales

This is a common combination. The telemarketing team is responsible for the national small orders (below 10,000 ~ 20,000), and the larger business opportunities are handed over to the local or nearby direct selling team for door-to-door transactions. Market leads are graded by SDR team.

Combination b, direct selling +KA

This is more suitable for customers with a large unit price span, ranging from 20,000 to 80,000 for direct selling teams to 100,000 to 200,000 for KA teams that need solutions. The division between them can be made by the directory system, and KA is responsible for the big customers in the directory; Other target customers are divided into local direct sales teams by region.

Combination C, Direct Selling+Channel

Direct selling is responsible for first-tier cities, and second, third and fourth-tier cities are handed over to channel agents. Both sides need to have clear geographical boundaries and reduce friction. Let the local direct sales and agency teams feel at ease to dig deep into the local market.

Combination d, channel+KA

The manufacturer (KA) is only a big customer, and the national flight contract is signed. Hand over all small and medium-sized customers to channel agents to complete signing and service. Different from the way that Group C strictly divides customer resources by region, Group D is divided according to customer size; There will be many intermediate areas in this division, and conflicts are inevitable.

Like Kingdee’s ERP products, it would certainly be better to use high, medium and low-level products (EAS/K3/KIS) to separate the boundary between KA and agents. However, SaaS companies’ products are organized in different ways and should not be so complicated.

 In addition to the combination of the above two team types, there are also SaaS companies that choose to combine three teams. In this way, the complexity is higher, and it is necessary to design a more efficient division of rights, responsibilities and interests of regions, resources, new purchases/additional purchases/renewal fees.

This article is the last article in the planning series for 2019-2020 (if you write it later, you won’t need it after you finish planning). Let me summarize it. Welcome to read and exchange messages:

# Business Sense Wu #(8) Planning should not be limited by the shortcomings of existing talents.

At the end of the year, I carefully created a course to help the business team develop: copying transactions-copying talents-copying teams. Tell the story of leading the team’s monthly performance to increase 60 times in 18 months and the management ideas behind it. Click to view related information.

The inside story about the car zebra system that 4S shop won’t tell you.

  About Zebra Zhixing system, it is estimated that students who are concerned about in-vehicle intelligent devices should have a little understanding. Under the joint research and development of SAIC and Ali, it should not be controversial to say that this set is the BOSS powerful in-vehicle intelligent system in China at present. It happened that I attended the launch conference of 360 South Region, and I wanted to experience a zebra system.

  Unfortunately, this deep test drive is still more inclined to control the experience, so now only three and one 360 are not equipped with Zebra Zhixing 2.0. One of them was equipped with Zebra Zhixing 1.0, and online celebrity experienced a remote starting car and some simple human-computer voice interaction.

  Looking at the beauty charging her eyes, I can only say that these instructions are too easy for the zebra system of 1.0, and the sharp tools such as drone following and natural spoken language recognition have not been displayed. However, it was clearly reported that the newly listed products will be equipped with Zebra System 2.0 on November 15th. I asked the marketing staff about the situation at the conference site and learned more inside information:

  Most of these areas are still equipped with the old zebra system, and only a few places, such as, can use Spot.0, which is still in the internal testing stage. It is conservatively estimated that the full coverage of the 2.0 system will not be upgraded until January 9.

  Everyone knows that the upgrade of zebra system is in the form of OTA (network download upgrade), which means that the change of system will not have any requirements for hardware, so students who are ready to start do not have to wait until the change of zebra system is completed. As for the size of the zebra system itself, you don’t need to worry about the traffic. This upgrade is free. At the same time, there is no need to worry about the lack of memory. The system itself has 8G cache and 32G memory, and watching more movies does not hinder it.

  However, it should be reminded that there will be two forms to upgrade the zebra system-one is that the user clicks and chooses to upgrade, which is fine; But another way to upgrade is to start the car, and the screen will be black and prompt for automatic upgrade. At this time, the car must not be extinguished, just like the mobile phone brushing machine, the program will turn brick in minutes.

  What will 2.0 Zebra add compared to the first generation Zebra system? First of all, wake-up and instructions can be output in one sentence, without waiting for the machine to respond after "Hello Zebra"; Secondly, the voices do not interfere with each other. If the co-pilot wakes up the system, the commands spoken by the main driver will be blocked. There are other details to upgrade here, but these two technologies are still quite awesome in the current human-computer voice interaction.

  The biggest highlight is undoubtedly that the zebra Zhixing system of 2.0 will be bound with Alipay. This function will complete the payment of gas stations, parking lots and toll intersections in the car, which is the rhythm of killing ETC and fuel cards … However! At present, this function of not getting out of the car can only be used in some places.

  The reason is that this in-car payment function needs the hardware cooperation of the payee. Just like the early WeChat payment, when the code scanner was not popular, the convenience of payment was simply not the same. So when will the in-car payment method be popularized? No one dares to say this. Just as a very humanized technology, this wave of attempts by Spot.0 is still of great value. If it can be as popular as WeChat payment, it will greatly reduce the payment time.

  Finally, talk about a black technology inherent in the zebra system. If you communicate with the zebra system of the same car for many times, the recognition and reaction speed of the machine will gradually improve, and even you can begin to understand your individual sentences with dialects, will you be terrified? In fact, this learning system that constantly adapts to the owner’s language is conclusive, and the coaches and market personnel at the scene have given a positive answer to this.

  In addition to language learning progress, it can record the driving habits of car owners, thus fine-tuning the control. For example, the zebra system can record and transmit this habit to the owner who violently steps on the accelerator, and has adapted to the more accelerated shift logic; According to the severity of the brakes, the zebra system will also classify them to adapt to different braking situations; In addition, memory settings such as temperature, volume and seat position are not to mention. From this point of view, the self-learning ability of artificial intelligence is displayed on the zebra system.

  In a word, after the understanding of this SAIC conference, I have a deeper understanding of Zebra Zhixing System 2.0-compared with the once simple instruction-telling operation, a rolling-level interactive system is being updated and iterated, which may change not only driving, but also a way of life.

  Back in the world, online celebrity, as a self-owned brand of Internet car, this wave of cooperation and exploration with Zebra system has also played a pioneering role. I hope this online celebrity can continue to spread positive energy, so that even the whole country’s car networking can step out of a more compelling new world next year.

Free clinic consultation

Free clinic consultation

Chu Liyun, female, born in July 1966, enlisted in the army in July 1981, with a level 5 professional skill. She is currently the chief nurse and head nurse of the Third Division of the Cadre Ward of the 401st Hospital of the People’s Liberation Army, and is the mother of Comrade Zhang Xuejiao at Qingdao Frontier Inspection Station. Since graduating from the military academy in 1984, this comrade has been rooted in the clinical front line for 33 years, showing the value of life by caring for patients, improving the quality of work by continuous exploration and enterprising, interpreting angel’s love with scientific human management, and silently doing nursing work in ordinary posts to the extreme, practicing the Nightingale spirit with practical actions of respecting every patient and being kind to every life. Because of outstanding work achievements, He has been rated as "Top Ten Nurses", "Excellent Nurses", "Excellent Head Nurse" and "Excellent Communist party member" in the hospital for many times, and has been awarded many honorary medals such as "Advanced Woman" and "Ideal Shines in the Post" by the Navy North Sea Fleet. For three years in a row, it has been rated as "excellent service star" in Qingdao health system, "civilized worker" in Qingdao health system, "good nurse satisfied by the people" in Qingdao, the fourth "Li Guimei’s good nurse" nursing outstanding contribution award in Qingdao, and Qingdao "Adhere to the clinical good nurse for 30 years and the "most beautiful head nurse" in Qingdao; He was awarded the title of "Excellent Nurse" and "Excellent Nursing Worker" in the Ninth Branch of jinan military area command for many times, and won the third-class merit three times.

Filial piety to parents-in-law, caring for husband and teaching daughter are the "wife’s help" in the neighborhood.

Shortly after Chu Liyun got married, his father-in-law was diagnosed with advanced esophageal cancer, and he could not eat through his mouth, so he could only maintain his life by intravenous infusion. Because her family agreed to hide her illness from her father-in-law and refused to send her father-in-law to the hospital, Chu Liyun took the initiative to assume the responsibility of home care. No matter whether she worked at night shift in the unit or worked at night shift, no matter whether it was windy or snowy, she took a trip every day and rode her bike to and from more than 20 kilometers. More than half a year after her father-in-law died, she never stopped. When my father-in-law died, he left a last wish that "her lover must apply for graduate school." To this end, she has undertaken almost all the housework and tried her best to support her lover to concentrate on studying for master’s and doctoral students. In six years, she spent a lot of time together. While working, she took care of her ailing mother-in-law, while taking care of her daughter’s preschool education, and cultivated her daughter’s interests in dance, calligraphy and painting. Her paintings and calligraphy won the first and second prizes in the National Children’s Painting and Calligraphy Competition. After enlisting in the army, Zhang Xuejiao gave full play to his literary and artistic expertise, and directed more than 10 special cultural programs such as dance and allegro, which were performed in the cultural performances of provincial offices, corps and Qingdao Cooperation Zone successively, and won unanimous praise from officers and men.

Benevolence and kindness nursing are recognized as "service stars" by doctors and patients.

As the head nurse in the cadre ward above the military level, I can’t remember how many different roles she played — Granddaughter, daughter, sister, comrade-in-arms … … In 2015, a 97-year-old veteran cadre was unconscious due to a sudden cerebral hemorrhage. She took meticulous care of her like a baby. She lived in the department for several days and guarded her bed. After the veteran cadre woke up, she heard about this and pointed to her wife. Emotionally said: "This is our own daughter!" . When she was discharged from the hospital, she was specially presented with a banner, which read "To Head Nurse Chu Liyun: She is extremely enthusiastic about her comrades and is active and responsible for her work". In addition, she insisted on visiting newly admitted patients within 12 hours, patrolling the ward at least twice a day on weekdays and at least once a day on holidays, keeping abreast of patients’ needs and doing her best to solve problems for patients; She insisted on taking the initiative to leave her mobile phone number for every hospitalized patient, and turned it on 24 hours a day, so as to be responsive, answer questions and be on call.

In 2002, as one of the first nurses sent abroad to study in the hospital, she went to Japan to study clinical nursing and nursing education. After returning home, she eagerly updated her knowledge, assiduously studied related rehabilitation skills, and applied the early rehabilitation concept of cerebrovascular disease to clinical work, which was highly recognized by her peers. In 2006, she was selected by the hospital and sent to the special training center of Run Run Run Shaw Hospital affiliated to Zhejiang University for venous catheterization technology. After strict examination, she successfully obtained PICC technical qualification certification, and now she has successfully placed catheters for more than 1,000 patients, improving the level of venous treatment in the hospital. A patient from Taiwan Province was in hemorrhagic shock due to sudden upper gastrointestinal bleeding, and her blood pressure could not be measured. She quickly and skillfully performed central venous catheterization for him through femoral vein, established a safe venous passage, and transfused 3000ML for 2 hours, saving the patient’s life. A patient with esophageal cancer survived for nine months after PICC intubation, and his family regarded PICC intubation as a life channel. The diligent pursuit of her career has yielded fruitful results. She once participated in the "First Naval Nursing Technology Competition" on behalf of the hospital and won many awards such as individual event, pentathlon and group. Also won the first prize in Qingdao vein indwelling needle competition. In addition, she has served as the coach and evaluation of nursing technology competitions organized by hospitals, logistics department of Qingdao base, Qingdao base, North Sea Fleet Air Force, North Sea Fleet and Qingdao for many times, and trained many nursing technical backbones for grass-roots health units of the army.He has published 20 professional papers and 5 monographs by the first author, and successively won one third prize for military medical achievements, four third prizes for military scientific and technological progress, one second prize for Qingdao scientific and technological progress, one third prize for Shandong scientific and technological progress, two national utility model patents and one national invention patent.

Chu Liyun’s selfless, selfless and conscientious professionalism has brought her a personal influence. Zhang Xuejiao worked hard in her post and worked hard for many years. In 2015, she was commended as an "advanced individual in law enforcement" by the Border Defense Bureau of the Ministry of Public Security.

Perseverance, courage and responsibility are the "loving elder sister" respected by officers and men.

During his 36-year military career, Chu Liyun has participated in military medical support tasks many times. In December 2015, she was nearly 50 years old. With the strong support of her family, she actively requested to participate in the 22nd escort mission of the Navy and served as the party branch secretary of the medical team. During the seven-month mission, he not only withstood the severe physical and mental tests of various complex sea conditions, but also took the lead, actively participated in various exercises, and always served every officer and soldier patiently and meticulously with full work enthusiasm. Take the initiative, carry out health knowledge teaching, and organize self-help and mutual rescue training and competitions for officers and men in war injuries. Actively participate in the rescue and care of the fishermen of the "Zhangyuan" in the Gulf of Aden. In every medical emergency, she always takes the lead and rushes to the front, showing the good image of female soldiers in China. Many media, such as People’s Navy Daily and Zhongxin. com, have given special reports, and the escorted officers and men are affectionately known as "loving big sisters". Mother and daughter always encourage each other tacitly, whether they are concerned about their daughters during the voyage across the equator or worried about their mothers in the Gulf of Aden mission area. They are both close friends and like-minded comrades-in-arms. Zhang Xuejiao proudly said: "Mom is escorted by one person, and our whole family is glorious. My mother has set a good example for me as a revolutionary soldier, and I will work harder like my mother. " Engaged in information legal work, often have to work overtime,Sometimes she works continuously until late at night. Zhang Xuejiao never complains that she is tired and full of energy.

Enthusiastic public welfare and selfless dedication are the "most beautiful head nurses" praised by the masses.

Years of work practice have made Chu Liyun feel that as a head nurse, it is far from enough to rely on one’s love, patience and compassion. Only by bringing out an excellent nursing team, cultivating a group of excellent nursing talents and creating a series of advanced nursing cultures with a responsible attitude, scientific management and innovative spirit can we be truly responsible for the nursing cause. And she is willing to devote her life to this great and beloved cause. The nursing group led by her has been rated as "advanced clinical teaching department", "excellent training department" and "advanced nursing unit" for many times. "Standardized nursing unit with high quality service", the "excellent nursing unit" of the ninth branch of the Joint Logistics Department, was jointly commended by the Ministry of Health of the People’s Liberation Army General Logistics Department and the Ministry of Health in 2010 as "demonstration ward with high quality nursing service". In 2014, it was named "Top Ten Outstanding Nursing Teams" in Qingdao. The "Rose in the Army" initiated by her — The Nightingale Nursing Volunteer Service Team of 401 Hospital often uses holidays to go deep into street communities to carry out free clinic activities for the people, carry out health education and rehabilitation guidance, and is welcomed by the masses. She has lived for decades,Leading nurses to regularly and voluntarily replace catheters, fistulas, nasal feeding tubes, PICC catheter maintenance, skin and wound care for patients with mobility difficulties after discharge. Many patients said in thank-you letters: "The head nurse thought of the front of the patient and did it in the patient’s heart!" Other patients’ families embroidered "meticulous care and consideration" on the banner. She also often uses her rest time to go to nursing homes for nursing business guidance, persistent dedication, and convey the warmth of angels with true love. In May this year, Comrade Chu Liyun won the title of "the most beautiful head nurse" in the activity of "Looking for the most beautiful head nurse" carried out by Qingdao News Network.

Voice interaction has been played with new tricks? !

Wisdom reported on April 2nd that on Monday, Baidu released the industry’s first end-to-end speech language model based on new Cross-Attention, which has been launched online for free.

Summarize the newly upgraded essays with several key words: voice interaction.Ultra-realistic, ultra-low delay and ultra-low cost.

Super-fidelity refers to the fact that Wen Xiaoyan, equipped with a large phonetic language model, can understand Chongqing, Guangxi, Henan, Guangdong, Shandong and so onCharacteristic dialect can also realize emotional dialogue.; Ultra-low latency means that the waiting time of users can be reduced from the common 3-5 seconds in the industry toAbout 1 second, almost the same as talking to real people; Ultra-low cost means that in the voice question-and-answer scenario of telephone voice channel, the call cost is about lower than the industry average.50%-90%。

Jia Lei, chief architect of Baidu Voice, revealed that the model can be deployed on L20 card, and under the condition of meeting the delay requirement of voice interaction,The concurrency of dual L20 cards can be more than several hundred.. At present, the training process of speech language model is convenient, which can be realized by optimizing hundreds of cards in one week based on Wenxin model, and the optimization work itself is not complicated.

Compared with the application of big model in voice interaction scene, what is the uniqueness of this big model of voice language? How to reduce the call cost to 90% at the highest? How to interpret the innovation behind it? Zhi Dongxi had an in-depth exchange with Jia Lei, chief architect of Baidu Voice, trying to find the answers to these questions.

First, the real-life dialogue experience, the upgraded version of the text Xiaoyan voice interaction is more silky

The development of large-scale model in voice interaction scene is evolving towards a more natural, low-delay and highly realistic voice interaction experience. And this more anthropomorphic interactive experience, we get a glimpse of the embryonic form in the newly upgraded Wen Xiaoyan, which is equipped with an end-to-end phonetic language model and has become an emotional companion and all-round assistant.

First of all, Wen Xiaoyan has integrated information query including weather query, calendar query, unit conversion, stock price and so on.38 vertical assistantsIt can be seen that the efficiency of voice interaction is much higher than that of text interaction in these special scenarios.

Secondly, Wen Xiaoyan is rightProblems of timeliness and non-timelinessCan cope with encyclopedic inquiry, timely question and answer content of current political knowledge, and Wen Xiaoyan can search in real time, and follow the instructions accurately to reduce hallucinations; Non-timeliness issues such as common sense questions and answers are not a problem.

Finally, it is also the biggest difference between voice interaction and text. Wen Xiaoyan can be carried out with users.Emotional and natural communication, and can respond to feedback quickly, and realize realistic and anthropomorphic interaction effect.

Not much to say, let’s take a look at the actual effect of Wen Xiaoyan.

A major difficulty in speech recognition is dialect recognition. The pronunciation characteristics of dialects are rich and varied. The same dialect may have different pronunciations in different regions, and even the same word may have different pronunciations in different contexts. This makes it difficult for speech recognition system to accurately capture and analyze all pronunciation variants, which increases the difficulty of recognition. At present, Wen Xiaoyan has been able to deal with the characteristic dialects in Chongqing, Guangxi, Henan, Guangdong and Shandong. He can not only understand them, but also reply with the corresponding dialects.

Another major feature of voice communication is the need for multiple rounds of interaction. For example, in the following example, Wen Xiaoyan not only gives a method to distinguish budgerigars from different dimensions of adulthood and childhood, but also gives correct feedback in time when users interrupt to ask new questions.

Even if the reply contains many elements such as distinguishing the budgerigar’s sex and distinguishing from a certain fixed feature, Wen Xiaoyan gives a concise answer, and at the end reminds the user that he can record while observing.

In addition, human-computer interaction is often interrupted in the middle, such as the user gets the core information he wants or is not satisfied with the current output content, etc. When the user interrupts the voice playback to input, the voice recognition system may be mistaken because of environmental noise, unclear pronunciation of the user or confusion with the previous voice content.

In the face of children’s repeated interruptions, Wen Xiaoyan can accurately identify their needs of "changing a story", and when children say "Mom has already told it", they don’t automatically choose to change the story, but give an emotional reply in time to create an atmosphere of natural dialogue.

Wen Xiaoyan, an emotional interactive form, also extends its application to companion scenes in assistant scenes such as knowledge quiz. When the user mentioned "I’m in a bad mood", Wen Xiaoyan’s voice was worried and so on, and guided the user to tell the reason why he was in a bad mood and further enlighten him.

Second, brand-new cross-related attention, to create a very low training cost advantage

Different from the language model, the core difference of the phonetic language model is that it can produce emotion.

Jia Lei said that the text model only produces words, while the phonetic language model can have emotions. The key is two special links in the architectural diagram of the phonetic language model.TN Rhythm and Emotion Control of Personality and StyleThis is prepared for speech synthesis, which allows the big model to have the emotion of adapting the content while generating the answer, which is also the key innovation of Baidu’s end-to-end speech model.

Specifically, there are four key innovations.

First of all, this is released by Baidu.The industry’s first cross-modal speech language model based on Cross-Attention; The second is the model.Combining Encoder with speech recognition, the calculation of KV is reduced to 1/10.; The third isEncoder is combined with speech synthesis, and the output content can be controlled emotionally.; Finally,Efficient full query attention EALLQA, so that the KV cache is reduced to a few tenths.

On this basis, the model realizesIntegration of text recognition and text synthesis.On the basis of systematic end-to-end communication, these coupled technologies enable the model to realize a natural, realistic and emotional interactive experience on the basis of quick question and answer and quick understanding.

Jia Lei explained that the acoustic model is also a phonetic model, but usually large language models are connected by words. Therefore, in the process of integrating speech recognition and large language model, researchers share the process of Encoder and speech recognition in large language model to achieve the purpose of reducing the hard delay of speech interaction, and innovatively introduce cross-modal modeling, switching from Self-Attention to Cross-Attention, thus completing the integration of speech recognition and large language model.

Baidu proposes to use Cross-Attention to solve the cross-modal problem of speech and language. In this process, due to the speed limitation of the existing Attention technology in Cross-Attention speech language modeling, Baidu developed the EALLQA technology suitable for Cross-Attention, adopting implicit RNN two-level position coding, training MHA in 128 space, and inferring MQA in 512 space shared by all layers of the model, so as to achieveMake full use of limited training resources and reduce reasoning cost..

In the basic training of the model, Baidu uses self-distillation post-train the end-to-end speech language model of Cross-Attention based on the pre-training model of Self-Attention mature Wenxin language.

In fact,In speech model, the pressure of KV cache and KV calculation is much greater than that of text model.. Jia Lei explained that the essential difference between speech recognition and text model is that the first token at the beginning of a sentence determines the delay of speech recognition. For the large text model, users can wait for 2-3 seconds to give an answer after entering a paragraph of text, while in the large speech language model, users are less tolerant of reply delay, and they hope to hear the answer within 0.5-1 second.

On this basis, the end-to-end speech language model realizes low-cost training and low-cost high-speed reasoning. In addition, the speech language model also needs quick response and emotional response, which is the scene where another key technology is exerted.Streaming word-for-word LLM-driven multi-emotional speech synthesis. Jia Lei said that many rounds of continuous communication with emotion can make people want to continue communication.

Based on the streaming word-for-word method, its speech synthesis is to see one word jumping one word at a time, and the large model can help the speech synthesis to output the text normalized output, prosodic pause output and emotional output it needs, making the speech synthesis process flow like when people speak, and its adaptive emotional coverage can reach 17 kinds according to the text output.

In addition, there is a big pain point in speech recognition, which is that it can’t judge the starting point and ending point of the user’s speech, butLarge model blessing can make it analyze whether the user’s words have ended based on semantics.The semantics are incomplete and we need to wait.

Jia Lei further explained that,The activation of voice scenes requires extremely interactive cost, extremely fast delivery speed, intelligent and emotional humanized question and answer.. Baidu integrates speech recognition with large model to solve the problems of pre-fetching, hesitation, content understanding and quick question and answer, and integrates text synthesis with large model to output prosodic emotion needed in speech summation, thus solving the problems of context understanding and emotion control in synthesis. This makes the application potential of voice scene greatly improved.

Third, directly attack the difficulty of voice interaction, and enlarge Baidu’s end-to-end voice language model.

The continuous optimization of large model has significantly improved the robustness, naturalness and speaker similarity of speech, butThere are still many pain points in the previous technical path.This is why Baidu focuses on the end-to-end speech language model.

Compared with the communication between people, the response speed of large language model is slow, and users need to wait for a while to get a reply. In addition, voice communication is often accompanied by multiple rounds of dialogue and interaction, and it is extremely difficult for models to complete colloquial multiple rounds of interaction. Compared with texts, users use more scenes of voice interaction, and the surge of interaction will lead to the increase in the application cost of large-scale models, and the difficulty of large-scale application popularization will also increase.

On the traditional voice interaction route, it will be limited by the accurate response between contextual memory, noisy occasions, hesitant questions and interruptions.

Therefore, this has become a core contradiction in the field of voice interaction.The convenience of voice interaction determines its potential for large-scale application, and these pain points are hindering its popularization.Jia Lei believes that,The chemical reaction between speech and text is the key to find a breakthrough in a specific field in the future..

The appearance of phonetic language model is qualitative change, and its innovative synthesis technology makes the model not need to see the whole text of a sentence, but can synthesize a word by seeing the text of a word. On this basis, Baidu has excavated a unique application scenario. He gave an example. For example, when asking about the weather, users can quickly interrupt the next question when they get the temperature range of the weather. Its advantage is that the use cost of the model is greatly reduced, while the text model needs powerful hardware to achieve such efficient application, but the speech language model can achieve efficient concurrency with low-cost hardware.

At the same time, from the perspective of the whole voice interaction field, the accuracy of the speech recognition part of the large model has been greatly improved. Jia Lei believes that it is more a competition of speed, cost and answer accuracy.Cost reduction is the key to large-scale use of multimodal voice interaction..

Jia Lei said: "Cost reduction is the inevitable way of technological progress." The extremely low cost of Baidu’s speech language model means the possibility of large-scale industrialization. The landing application of AI is the core of the development of the model industry in 2025, and this model is the key to solving the speech problem.

Baidu’s accumulation in the field of speech recognition has a long history.

In 2018, the Deep Peak 2 model released by Baidu Voice broke through the traditional model that has been used for more than ten years, greatly improving the recognition accuracy in various scenarios. At the beginning of 2019, Baidu voice technology team announced the world’s first streaming multi-level truncated attention model SMLTA in the field of online voice, with a relative accuracy rate of 15%. In 2021, Baidu released the streaming truncated conformer modeling technology based on historical information abstraction-SMLTA 2, which solved the problems faced when the Transformer model was applied to online speech recognition tasks.

These technological innovations have been applied in many fields such as automobiles, consumer electronics and mobile phones. This time, in order to promote the large-scale application of speech language model, at present,Baidu has launched its online Xiaoyan and opened it for free, and plans to launch it on the open platform in April, and then it will be connected to call centers, speakers and other business lines..

Jia Lei mentioned: "Science may have national boundaries, but it has no corporate boundaries." Subsequently, Baidu opened the end-to-end speech language model, just to promote the application of the big language model in the speech field, which is conducive to the development of the whole industry and ecology.

Conclusion: Baidu’s phonetic language model is unsheathed, opening a new chapter with low cost and high efficiency.

Convenient, efficient, natural and friendly voice interaction, which is widely used in multiple scenes, is very important in the digital age. However, from the current actual effect, voice interaction has greatly improved in recognition accuracy, and now the competition focus of the industry is on its recognition speed, cost and accuracy of answers.

In this context, the release of Baidu’s end-to-end speech language model further broke through the cost, and proposed a new technical path, which pushed the industry competition of voice interaction to a new height. At the same time, Baidu will launch it on an open platform, which will accelerate the application and popularization of large models in voice interaction scenarios.

How did 40 yuan’s shared charging treasure become a "price assassin"?

  Recently, the topic of sharing the price increase of charging treasures has rushed to the hot search. Beijing Youth Daily reporter saw that at present, the price of most charging treasures is 3-4 yuan per hour, and the highest is up to one hour in 10 yuan. Consumers said that they can’t see the price before renting, and hope that manufacturers can increase price transparency.

  High price and slow charging.

  Shared charging treasure was spit out.

  The reporter of Beiqing Daily learned that the price of most charging treasures in Beijing urban area is 3 yuan/hour, while the price of most charging treasures in Sanlitun business district is 4 yuan/hour, and one place reaches 6 yuan/hour. Some netizens reported that the shared charging treasure in some areas needs 10 yuan for one hour.

  The reporter of Beiqing Daily saw next to a vertical charging treasure cabinet in Sanlitun that seven or eight people were lending and returning charging treasures in front of the cabinet within five minutes.

  "When it was cheap a few years ago, it was one or two yuan an hour. In recent years, it seems to be three or four yuan." Many consumers said, "4 yuan’s charging treasure is expensive, and you can buy a charging treasure after renting it for ten times."

  Many users also said that the shared charging treasure is slow to charge. The reporter of Beiqing Daily randomly rented charging treasures from three different platforms, and the display of Meituan was 5V=2.4A, which is 12W;; Monster charging display 5.0V=2.0A, that is, 10W;; The display of small electricity is 5V=2.1A, which is 10.5W. At present, the charging interfaces of mainstream mobile phones are all at 67W and 120W. This means that if it can be fully charged in about half an hour, it will take at least 4 hours for the charging treasure to be fully charged with an ordinary capacity mobile phone battery. This means that it takes consumers about 12-40 yuan to fully charge the electricity once.

  Merchants set their own prices.

  The platform is still "burning money for the market"

  The reporter of Beiqing Daily found that there are mainly four shared charging treasure industries: Meituan, Monster Charging, Small Power and Street Power. Many platform operators have revealed that "the rental price of charging treasure is determined by the merchants, and the platform does not interfere much." When asked whether it is reasonable to price 5 yuan /30 minutes or 9 yuan/hour in busy areas, they all said that it is still within a reasonable range. Only when the price is too high and no one rents it, the platform will provide some suggestions to help merchants get profits.

  Chen Liteng, an e-commerce analyst of life service in the E-commerce Research Center of Netscape Society, said that the shared charging treasure in the past had unlimited scenery. However, the single profit model made it difficult for the shared charging treasure to develop further, and the market’s enthusiasm for the shared charging treasure was also declining.

  The reporter of Beiqing Daily learned that the financial report of Monster Charging in the first quarter of 2022 showed that the operating income in the first quarter of this year was 737.1 million yuan. From the operational data, the POI and the cumulative number of registered users of Monster Charging maintained a growing trend, and 12 million new users were added this quarter, with the cumulative number of registered users reaching 298.9 million and the number of online shared charging treasures reaching 5.7 million. However, in this case, its net loss reached 96.41 million yuan, compared with a profit of 15.1 million yuan in the same period last year. This is the third consecutive quarter that Monster Charge has suffered a loss, and the loss has an expanding trend.

  The listing plan of Xiaodian Technology has also run aground. According to its prospectus, Xiaodian Technology achieved net profit of-36 million yuan, 137 million yuan and-104 million yuan respectively from 2018 to 2020, and the adjusted net profit was-45 million yuan, 194 million yuan and-107 million yuan respectively. According to its prospectus, the incentive fees paid to point partners and channel partners are 105 million yuan, 715 million yuan and 1.013 billion yuan respectively, accounting for 25%, 44% and 53% of revenue respectively. A similar situation can be found in the financial report of monster charging. This means that platform companies are very dependent on channels and are still in the stage of "burning money" for market share.

  Single income restricts development

  The opaque charging standard affects the experience.

  "The shared charging treasure of the same brand has different charging standards in different scenarios, and there are no specific rules for publicity, which leads to the phenomenon that most users of the shared charging treasure are related to the unreasonable charging of products." Some people believe that "the problem of different charging standards will affect the user experience, which will lead to a decline in the reputation of the industry and the loss of users. The single profit model is the main problem facing the shared charging treasure, which restricts the further development of the industry."

  However, analysts believe that product leasing is still the core business model of the shared charging treasure industry due to the limited factors such as small competition barriers for enterprises and low switching costs for users. But at the same time, brands are actively exploring other business models, such as developing customized products and cross-border cooperation.

660,000 Mercedes-Benz oil spill owners made 8 demands. Mercedes-Benz issued a statement apologizing.

  CCTV News:Recently, a video of "Mercedes-Benz female car owners defending their rights" detonated the network. In the video, the female car owner cried that in order to celebrate her 30th birthday, she bought a new Mercedes-Benz car for 660,000 yuan in a 4S shop in Xi ‘an, but it was only 5 minutes before she signed the bill to pick up the car, and she found that the engine leaked oil.

  Since then, within 15 days, she has repeatedly communicated with the 4S shop to solve the problem, but was told that she could not refund or change the car, and she could only change the engine according to the "three guarantees policy for automobiles". In this regard, the female car owner could not accept it. In desperation, she had to sit on the roof of the Mercedes-Benz in the store and ask for a statement.

  The 4s shop said that it had reached a settlement with the owner privately, but the owner said that he had not received any reply. On April 13th, the High-tech Branch of Xi ‘an Market Supervision Bureau has set up a multi-department joint investigation team. The female car owner said that she has met with the investigation team and put forward eight major demands, including investigating the history of the vehicle, testing the vehicle, formally apologizing and giving mental compensation.

  The owner said that it took five minutes to pick up the car, and it was found that the vehicle leaked oil. Then, did this oil-leaking Mercedes-Benz have quality problems before the sale? Continue to understand.

  On April 12, the reporter learned from the High-tech Branch of Xi ‘an Municipal Market Supervision Bureau that on the afternoon of April 11, the industry and commerce in the jurisdiction had already got in touch with the owner, and confirmed that the owner bought an imported Mercedes-Benz CLS300 sports car on March 27, with a bare car price of more than 580,000, including loan fees and other expenses totaling about 60,000.

  The staff of Xi ‘an Lizhixing Mercedes-Benz 4S store said that all vehicles, each 4S store is the same, and will be tested by the manufacturer, including the test in the store.

  According to the 4S shop, according to the three-guarantee policy for family cars, only the engine can be replaced for the owner. So how is the three-guarantee policy for family cars stipulated?

  The reporter inquired about the "Provisions on Responsibility for Repair, Replacement and Return of Household Automobile Products" and found that the "Regulations" clarified that household automobile products have product quality problems during the warranty period and can be repaired free of charge. Within the "three guarantees validity period", you can go through the formalities of returning or exchanging goods. Among them, the warranty period is not less than 3 years and 60,000 kilometers, and the validity period of "Three Guarantees" is not less than 2 years or the mileage is 50,000 kilometers. As for the conditions for returning goods, the Provisions on Responsibility for Repairing, Replacing and Returning Household Automobile Products lists four specific situations: The first one is that if the steering system fails, the braking system fails, the car body cracks and the fuel leaks within 60 days after the seller issues the car purchase invoice or within 3,000 kilometers, you can choose to exchange or return the goods.

  Beijing Mercedes-Benz Sales Co., Ltd. issued a statement on the 13th, saying that the company has attached great importance to it since it recently learned about the unpleasant experience of its customers, and immediately launched an in-depth investigation on this matter to know the relevant details as much as possible. Anyway, I apologize for the customer’s experience. The company has sent a special working group to Xi ‘an, and will make an appointment with customers as soon as possible to communicate directly, and strive to reach a satisfactory solution on a reasonable basis.

I want to talk to you about sex tonight.

 

At what age did people all over the world have their first night?

Durex, the eldest brother, made a global survey and found that the average age of men and women’s first sexual experience was17.3 years old.

17.3 years oldThe age of ordinary high school students.

When you are still an ignorant problem solver, you have been abandoned by your peers.

Is it too early?

On the other hand, aboveboard sex education came too late.

On October 17 this year, the National People’s Congress will "for the first time"sex education"The word is written into the Law of People’s Republic of China (PRC) on the Protection of Minors.

Prior to this, the obscure "adolescent education" was still used in laws and policy documents.

This is a great progress, but it illustrates a long-standing problem-

We still dare not talk about sex boldly.

We are always coy about the elephant in this room.

Don’t talk about it, does it not exist?

People in the room won’t mistake the elephant leg for a pillar and get hurt by it?

Japanese TV series17.3 About SexThat’s what we talked about.

More than 4000 people in Douban scored 9.1.

Different from the hot American TV series [Sex Study Room] in recent two years, this drama fits the relatively conservative gender culture in Asia and looks more resonant.

It is also a story about girls wavering and growing up between sex and love. sisterhood, who knows and supports each other, is very powerful.

 

01

The main characters are three 17-year-old female high school students, all of whom have a little knowledge of sex.

Or, I don’t understand at all.

The girl Yuliang is one of them.

Her boyfriend of a month sent her an invitation:

"Do you want to come to my house the day after tomorrow? There is no one at home."

Even though she saw the age of her first night published on the website, she was not psychologically prepared.

"17.3 years old, don’t you think it’s too early?"

"Will it hurt the first time?"

"Glass into the body so painful? Certainly not. "

But on second thought, it’s good to be an adult at the age of 17.3.

She prepared according to the instructions on the web page:

Choose a complete set of light-colored underwear that boys will like, and even shave off the body hair of private parts.

When she arrived at her boyfriend’s house, as soon as Yun Liang sat down, her boyfriend drew the curtains without saying anything and pushed her down eagerly.

Regardless of her wishes, she rudely took off her carefully prepared underwear and threw it on the ground.

"I feel like an object."

Yun Liang was afraid and disappointed, so she picked up her underwear and fled.

When she came to school the next day, she found that everyone knew about it.

It turns out that everything is just a bet made by my boyfriend and friends, betting that he can get rid of Yun Liang within one month.

And told the story about her shaving her body hair.

In embarrassment, Yun Liang ran to the dark biological room and cried.

Suddenly the curtains in the room were pulled open and the sun shone in.

Asahi, a usually taciturn male classmate, came to comfort her, saying that those boys were idiots who learned sex from AV and didn’t know how to respect girls at all.

Also published some opinions about "why girls cater to boys":

"Even depilation, also the boy to do. After all, the taste is big and the hair is thick and hard. "

Wonderful!

Yun Liang seriously recalled the original idea of getting rid of it, not because he really wanted to do it.

Catering to boyfriends is also misleading because of reading strange web pages.

It turned out that everyone didn’t understand the noise, so she decided to learn more about sex.

02

The other two girls also have their own confusion.

"Do we have to have sex?"

Girls have never liked anyone since they were young, and being kissed by boys will disgust and vomit.

She entered her "symptoms" on the Internet, and the result was-

No sexual love.

She came to the school library to check the information, but she couldn’t find it at all.

Finally, the biology teacher found out her own book and lent it to her.

After popularizing the knowledge of asexual love, the teacher told her,"It’s nothing strange to be different from others.".

Contrary to Xiao, the girl Nai has dated five boyfriends, each of whom is the only thrill.

The fifth one she met on dating software, and her profile says "26-year-old, IT male".

After you nai was with him, he contracted a kind ofsexually transmitted disease.

It was Yun Liang who found it in the book according to her symptoms.

I didn’t know until I went to the hospital for examination that the disease might be contagious even if I wore a condom.

It turned out that this boyfriend used a fake identity, but he was actually izakaya’s little brother, and he was sleeping with several people at the same time.

Nai decisively broke up and continued to invest in the next love.

She made a decision that she would go to the health center for a check-up before going out with every boyfriend in the future.

When the three girls encounter sexual problems, they all rely on themselves or friends to solve them.

It turns out that girls can also enjoy sex.

It turns out that sex is as diverse as people, and it is not surprising that it is different from others.

It turns out that condoms are not absolutely safe.

The school didn’t teach them relevant knowledge and didn’t provide environmental support.

Contact without knowing it is likely to get hurt.

The three of them were lucky to get effective guidance and help in time.

But wouldn’t it be better if someone told them this common sense from the beginning?

If you are troubled, the way you think of is to explore and discuss with your friends. This is the real "sex study room".

 

03

Sex education in schools is completely blank, and parents are also silent.

Yun Liang’s idea of virginity had something to do with her mother.

Yun Liang’s mother forbade her puppy love, which was very strict.

When you come back from school later, you will be questioned if you send a message to your friends.

Put a bear’s mating image on TV, and immediately switch to the weather forecast with the remote control.

It’s very much like the experience when we watched TV with our parents when we were young, and we had to pour water when we met the kissing scene.

I don’t think Yuliang’s skirt is too short, so I pull it down by hand.

So when Yun Liang found out that such a mother could masturbate, the whole person was shocked.

In the drawer of her mother’s bedroom, she saw the vibrator that her friend said.

It was the first time that she knew that women would do such a thing, which was unacceptable at the moment.

My mother, who can’t even say the word "physiological period" at home, doesn’t know how to explain it to her.

The relationship between the two fell into an awkward freezing point.

Finally, the biology teacher took her to the "women’s products" store, and the history of popular science vibrators made her understand that female masturbation is a natural thing.

Yun Liang later went to the store by herself, bought a new vibrator for her mother and quietly put it back in the room.

I also took care of my mother’s face and helped her turn over the article lightly.

Are there many cases where sex is taboo at home and the result is a rollover?

There is no lack of such questions in Zhihu:

It is not wise to cover up the obvious things in daily life.

Things that children should not know will be known by them sooner or later.

Knowing is not terrible, but misunderstanding and a little knowledge.

Even when a child is hurt, the first reaction is to hide it from his parents.

The girl mentioned above, Nai, was afraid to swipe her medical insurance card at home when she was in the hospital.

Her medical expenses were paid by three girls together.

It’s good to have friends’ support, but isn’t home called harbor and backing?

At this time, can the family provide support?

This may be too difficult for some parents.

I dare not talk about sex at home, and I am not allowed to talk about it at school.

In 2017, a Hangzhou parent saw the sex education book issued by the school, and thought it was too explicit, so he sent Weibo to boycott it.

Some people also questioned,"Knowing sex so early will make children have sex too early?"

This is actually a misunderstanding of sex education.

The purpose of sex education is to protect.

Avoid boys and girls who don’t understand sex being pitied.

In the play, Yun Liang’s junior high school friend Cheng Mei had sex with her boyfriend during the "safety period" and accidentally got pregnant.

By the time the test came out, it had been more than 22 weeks.

In Japanese law, abortion is not allowed after 22 weeks of pregnancy.

The school forced her to drop out of school, which meant that she was farther away from her dream of being a teacher in college.

How hard can it be for an underage single mother?

In the final analysis, she became a victim because she failed to get the correct sexual knowledge.

Actually,The content of sex education is not only the knowledge of sex and reproductive health.

Also includes the rightPositive attitude, sincere communication, respect for others and learning to ask for help.And other skills.

beLife education based on sex.

Professor Liu Wenli, who compiled this controversial reading, said that people’s desire to explore the body is innate.

So sex has nothing to be ashamed of and can’t be said.

Give sex disenchantment and treat it as a normal thing like the weather.

Know it well enough so that you won’t be hurt by it and taste its sweetness.

All this starts with talking about sex boldly.

Ding ~ the oil circle "fragrance" is coming!

March vegetables bloom,

Rapeseed is ripe in June,

Seed oil pressed in August.

picture

After four seasons of sowing in autumn, storing in winter, growing in spring and harvesting in summer, a grain of rapeseed has matured, and through the processes of removing impurities, frying seeds, squeezing, filtering and settling, clear, transparent and mellow rapeseed has entered thousands of households.

Everyone has appreciated the beauty of rape blossoms and tasted the fragrance brought by rapeseed oil, so how much do you know about rapeseed oil? Today, small farmers invited Hu Qiong, a researcher from the Institute of Oilseed Crops, Chinese Academy of Agricultural Sciences, to listen to experts talk about rapeseed oil!

The name of rape

At the end of the Eastern Han Dynasty, Fu Qian wrote "Popular Wen", which recorded that "Brassica is called Hu Cai", and "Brassica" was the ancient rape in China, which was often used as a vegetable at that time.

Later, people gradually discovered that rape seeds can produce oil, so they bred Chinese cabbage rape which can extract oil through breeding and domestication. Rapeseed is also named after "oil".

How rapeseed becomes vegetable oil

Generally speaking, rapeseed oil extraction technology can be divided into "pressing" and "extraction".

"Squeezing" is the physical and mechanical squeezing of rapeseed by using squeezing equipment to produce oil, which can be divided into cold pressing and hot pressing, among which hot pressing is more commonly used.

"Hot pressing" means that rapeseed is heated by frying, steaming, etc., and then mechanically pressed to produce oil; "Cold pressing" means that rapeseed is pressed without baking or slightly heating, and the "crude oil" squeezed by cold pressing needs heating and dehydration before it can be filtered out into clear vegetable oil.

In contrast, hot pickled mustard tuber oil is rich in flavor because of the influence of high temperature; Cold mustard tuber oil is clear and beautiful in color, but light in fragrance.

"Extraction" is to soak or spray rapeseed with an organic solvent that can dissolve oil, so that the oil in the oil can be extracted.

In addition, it is popular to extract vegetable oil by "microwave pressing" on the market at present. This method uses microwave to heat rapeseed, which can better control the temperature and make the color of oil clear. At the same time, it is also conducive to the efficient release and dissolution of nutrients and oils in rapeseed, and plays a certain role in enhancing fragrance.

N reasons for choosing vegetable oil

In general, three kinds of rapeseed, Chinese cabbage rape, cabbage rape and mustard rape, can be used for oil extraction. However, because of the strong disease resistance and good quality of Brassica napus, most of them belong to double-low varieties (low erucic acid and glucosinolate content) and high oil yield, so they are mostly selected for oil extraction.

      Fatty acid composition balance: the fatty acid composition in rapeseed oil is relatively balanced, and the saturated fatty acid content in vegetable oil is the lowest, about 7%.

High oleic acid content: It is pointed out in the Dietary Guide for China Residents that oleic acid can reduce bad cholesterol and increase good cholesterol. In the eyes of experts, oleic acid is also an important indicator to measure whether an edible oil is more conducive to health. At present, the oleic acid content of most vegetable oils sold in the market can reach 60%, and the oleic acid content of rapeseed oil with high content can even reach more than 70%, which can well meet the public’s demand for oleic acid.

picture

Reasonable ratio of linoleic acid to linolenic acid: According to the Standard for Healthy Edible Oil issued by FAO, the ratio of linoleic acid to linolenic acid in essential fatty acids should be less than or equal to 4:1. Linoleic acid and linolenic acid are one kind of unsaturated fatty acids, which cannot be synthesized by human body. The proportion of rapeseed oil is reasonable.

Rich in nutrients: Rapeseed oil also contains major trace elements needed by human body, such as iron, copper and zinc, and the proportion of vitamin E in rapeseed oil is relatively appropriate.

Rapeseed oil is currently recognized as "the healthiest edible vegetable oil for the public".

What is unique about "low erucic acid vegetable oil"

"Low erucic acid rapeseed oil" refers to rapeseed oil with erucic acid content not exceeding 3%. It is made by squeezing low erucic acid rapeseed, and the erucic acid content is much lower than that of traditional rapeseed oil.

At present, the United Nations Food and Agriculture Organization (FAO) and WHO have put forward a limited standard for erucic acid in edible oil, requiring that the erucic acid content in edible oil should be less than 5%. The standard of erucic acid content in edible oil in some countries requires that it should not exceed 2% of total fatty acids.

picture

In the chemical molecular composition of oleic acid and linolenic acid, the carbon chain is short, while erucic acid is a long-chain unsaturated fatty acid, which consists of 22 carbon chains. The long carbon chain is difficult to digest and has poor absorption and utilization rate, which will reduce the nutritional value of vegetable oil. And high doses of erucic acid can also induce myocardial fat accumulation, congestive heart failure and other diseases.

Now, the vegetable oil brands advertised as "low erucic acid rapeseed oil" in Shangchao and grain and oil stores are generally up to standard in erucic acid content, so you can buy them with confidence.

Tips for eating vegetable oil

No.1: which onesPeople are not fit to eat vegetable oil?

Rapeseed oil is suitable for all ages. Under normal circumstances, as long as there is no allergic reaction to the ingredients of rapeseed oil, most people are suitable for eating rapeseed oil.

However, in view of acute gastroenteritis, diarrhea and other diseases, it is suggested to control the dosage of vegetable oil. Although there is an old saying that "too much oil will not spoil vegetables", it is important to remember that too much oil will spoil people, so it is not advisable to drink too much cooking oil every day, just in moderation.

No.2: how to preserve the vegetable oil after opening?

It is recommended to keep it away from light and heat. Rapeseed oil after daily opening can be stored in a glass bottle for sealing, away from the stove, and placed in a dark cabinet, so as to avoid the emission of effective components in the rapeseed oil and not affect the fragrance and taste of the oil.

No.3: what is the best way to eat vegetable oil?

The content of unstable fatty acids in rapeseed oil is less, so it will not form too many trans fatty acids harmful to human body after heating, and high-temperature cooking can release the fragrance of rapeseed oil well and enrich the taste of vegetables.

Rapeseed oil is listed as the first choice for making Chili oil because of its strong fragrance, bright oil and high temperature resistance. Stir-frying rapeseed oil and pepper at high temperature can effectively blend their unique flavors and increase the overall flavor of Chili oil.

If it is high oleic rapeseed oil, its stability is better. Compared with other types of vegetable oil, it can withstand high temperature heating and repeated frying. Suitable for making fried food, such as fried dough sticks, French fries and other foods.

In addition, the fragrance of normal temperature rapeseed oil itself is not as rich as sesame oil, and if it is used to mix cold dishes without heating, it may not taste particularly good. Therefore, if the heated vegetable oil is used to mix cold dishes, the oil fragrance will be more obvious.

Food is the most important thing for the people.
