Tsinghua is a chip veteran who specializes in GPGPU! Seize the domestic gap

  Aspect: GPGPU processor developed by Denglin Technology adopts software and hardware co-design and will be used by customers for testing at the end of this year.

  Lead: The new concept of "AI chip" has gradually gone through the stage of popularization in the past year and is more and more familiar to the public. In the process that the industry has gone through barbaric growth and started to accelerate its landing and integration, more AI chip companies have also begun to step out of their own differentiated routes.

  After the first season of previous AI chip series reports, Zhidongxi set out again, and further conducted differentiated in-depth follow-up reports on nearly 100 core enterprises in the whole AI chip industry chain. This is one of the second seasons of the series of reports on the AI chip industry in Zhidongxi.

  When it comes to universal AI chips, no one will ignore NVIDIA.

  With the super parallel processing capability of GPU, NVIDIA got on the high-speed train of artificial intelligence (AI), and in recent years, its market value soared by more than ten times, making it invincible in the field of AI chips in data centers and becoming an unshakable cloud AI overlord.

  The outbreak of computing power provides the cornerstone for the accelerated development and landing of AI technology. The hot AI market has spawned a number of emerging AI chip entrepreneurs at home and abroad.

  In the past, chip giants such as NVIDIA and Intel dominated the cloud AI market, and most AI chip startups chose to avoid its edge and specialize in the field of terminal AI-specific chips.

  However, one company named "Denglin Technology" has a unique vision, aiming at GPGPU, which is now controlled by NVIDIA. GPGPU is the full name of general purpose computing on graphics processing unit, that is, a graphics processor (GPU) capable of general computing. It extends the application scope of GPU beyond graphics, and has been widely used in large-scale parallel computing in scientific research, education, financial computing, industry and other fields.

  At present, only NVIDIA has realized the large-scale commercialization of GPGPU in the world, and the gap in this field in China is still obvious, but several players have been working hard to develop it.

  ▲ Li Jianwen, founder and CEO of Denglin Technology

  On a warm morning, Zhi Dongxi chatted with Li Jianwen, the founder and CEO of Denglin Technology, to see how this veteran who has been deeply involved in GPU for 20 or 30 years led the team to develop innovative GPGPU architecture with versatility and high efficiency, and moved towards the vision of "becoming the NVIDIA of China".

  GPU veterans have been in business for a year and a half, and more than a dozen patents are in hand.

  As the mainstay of AI development, the opportunities for the underlying hardware of AI are undoubtedly extremely broad, but looking around, most of the solutions for cloud AI training in the world are provided by American company NVIDIA.

  The design of high-performance processor is facing many challenges such as high complexity, technical difficulty and deep technical barriers. It is a key field in the field of integrated circuit design, and the relevant talent pool is very limited, even in Silicon Valley, where many IC elites gather.

  Li Jianwen studied in Tsinghua University Institute of Microelectronics with a bachelor’s degree, and obtained a master’s degree from the Circuit Teaching and Research Group of Tsinghua Radio Department in 1990.

  As early as 2017, Li Jianwen began to think, why don’t we build Chinese’s own server AI chip?

  This idea became the bud of Li Jianwen’s founding of Denglin Technology.

  Before the establishment of Denglin Technology, Li Jianwen had twenty or thirty years’ experience in GPU field. He served as the vice president of TUxin Technology (founded in 2004), and the GPU/GPGPU IP products he was in charge of were sold to famous semiconductor and technology companies such as Freescale, Intel, Meiman, Google, Samsung, Nokia and Dahua.

  At first, Li Jianwen was also attracted by Google TPU, and wanted to have a try on special AI chips. However, during his time as a consultant of Northern Lights Venture Capital, Li Jianwen found that in the face of the rapid evolution of algorithms and the emergence of new applications, the special AI chip similar to Google TPU does not have the versatility needed by the market. Maybe after investing a lot of money and time to make the chip, the market no longer needs this thing.

  After seeing the bottleneck of dedicated AI chip, based on years of accumulated industry experience, Li Jianwen is determined to make some achievements in the construction of heterogeneous general computing platform with GPGPU as the core, and make GPGPU solutions with better performance than NVIDIA.

  In November 2017, Li Jianwen established Denglin Technology in Shanghai, which was hatched by the well-known high-tech venture capital institution "Northern Lights". The Angel Round and Pre-A Round of financing were completed at the end of 2017 and the first half of 2018 respectively, with a total financing amount of about 150 million RMB.

  The core founding team of Denglin Technology consists of eight people, seven of whom have been deeply involved in the GPU field for a long time, and one has rich experience in network processors.

  According to Li Jianwen, other members have worked for many years in world-renowned semiconductor, system and Internet companies such as TUX, NVIDIA, AMD, Cisco and Acacia. Each member not only has more than 20 years’ experience in high-tech industry, but also has the achievements of successful streaming and mass production in advanced technology from 28nm to 7nm, and comprehensively covers the parallel processor system architecture, software and hardware, core IP, processor verification platform construction, and the development of the overall SoC chip.

  After a year and a half of development, there are about 60 people in the company now, most of whom have at least a master’s degree, no less than 78 years of work experience and very rich industry experience. At present, Denglin Technology has obtained more than a dozen patents, and dozens of core patents are being applied at home and abroad.

  Software and hardware combined with innovative GPGPU will be delivered to customers at the end of this year.

  With NVIDIA GPGPU Zhuyu in the front, if a startup wants its products to be recognized by the market, it usually chooses to cut prices and earn less money.

  But Li Jianwen wants to do more than that. He hopes to do something different. He can not only inherit the advantages of NVIDIA, but also be as good as NVIDIA’s GPU in universality. At the same time, he has made some innovations in technology, which makes the calculation density higher, the efficiency further improved, and the demand for external bandwidth greatly reduced.

  In people’s traditional cognition, NVIDIA’s GPGPU core is mainly oriented to graphics acceleration and high-performance computing, but in order to take into account the characteristics of all these applications, his hardware structure is fixed, the execution mode is based on instruction set, and the storage is centralized data storage based on the traditional von Neumann architecture, which limits the efficiency of hardware to some extent and is not the optimal solution for AI applications.

  Therefore, Li Jianwen chose to adopt the concept of software and hardware co-design in the system architecture design, so as to solve the problem of both universality and high efficiency of AI computing.

  Different from the customized AI processing chips provided by other manufacturers, the "boarding -Minsky" architecture (software-defined heterogeneous AI computing platform) independently innovated by Denglin Technology has higher flexibility in architecture design.

  The software can predict the final application of customers. Through feature analysis at a higher application level, various hardware designs including pipeline, control model and storage model can be optimized according to the characteristics of tasks.

  Through this architectural innovation, Denglin Technology can make the computing density and efficiency of AI processor hardware higher, the power consumption and area lower, and the requirements for bandwidth are much lower.

  "It turns out that it’s like handing over the task to the right hand after the left hand has done something, and the way of software and hardware collaboration is that the two hands work together." Li Jianwen vividly metaphor.

  According to him, compared with Tesla V100 and Tesla T4, the latest mainstream products in NVIDIA, the products of Denglin Technology have improved their performance by 5-10 times on the basis of lower-cost mature technology and reducing the chip area by more than 50%.

  At the same time, it is unrealistic for a startup company to re-create a set of software ecology directly before it grows up. Therefore, Li Jianwen chose to inherit the ecology with NVIDIA as the main body and provide better solutions.

  Li Jianwen revealed that the GPGPU processor at the core of Denglin Technology has passed the FPGA verification, and the design of the first generation product Goldwasser has also been completed, which is being fully verified before streaming. The product is planned to be available for customer testing before the end of this year.

  Startups need to see three directions clearly.

  Li Jianwen believes that it is very important for a new company to understand three aspects: one is the market, the other is the technology and product route, and the third is that the market and technology direction should be consistent with the team’s ability.

  First of all, the AI hardware market is developing rapidly, which is recognized by everyone. According to the report of American research institute Tractica, by 2025, the market of cloud AI chips is expected to reach $14.6 billion.

  At this time, the choice of technology and product route is particularly important. Because the iteration speed of the current AI algorithm is still very fast, Li Jianwen thinks that the risk of developing a special AI chip will be greater. Relatively speaking, the route of a general AI chip is more secure and feasible.

  Even if you see the market opportunity and find the potential technology and product direction, you need to have the ability to be good at this field. Similarly, taking Denglin as an example, most of their members have mature experience in the GPU field, and they have practitioners with excellent professional and technical skills from software and hardware, IP to SoC, so they have the ability to solve problems quickly and develop products.

  Previously, with the increasingly hot AI chips, a large number of fans poured into this market. However, as the capital market became calm, people began to question whether there was a bubble behind this carnival.

  For this phenomenon, Li Jianwen thinks that the market is a little overheated. Some people and capital who jumped in underestimated the difficulty of cloud AI processors, but PPT can’t make chips. The ultimate winner must be someone who can have a deeper understanding of customers’ ideas and make products that truly solve customers’ core problems.

  Conclusion: The landing tide of large-scale AI chips has not yet arrived.

  Last year, it can be said that the domestic and international science and technology circles were involved in a frenzy of AI chips. Both traditional semiconductor companies and AI chip entrepreneurs stood their ground, and various cloud computing companies, AI algorithm companies and traditional industry giants poured in across borders, vying to announce their own research on AI chips.

  They chose different technologies and product paths to meet the needs of different application scenarios such as data center, security and voice.

  According to the AI chip plans announced by various companies before, there will be a number of products of AI chip companies at home and abroad one after another this year and next. From the underlying hardware to the adaptive solutions, the competition in the field of AI chips will become more intense. The bursting of any bubble will be accompanied by the disappearance of a large number of start-ups, but after the strong wind blows, the start-ups that really grasp the market needs and solve customer problems will stand out.

Wang Baoqiang visited the group performance with "New king of comedy" to cheer for "drifting"

       The film "New king of comedy", directed by Stephen Chow and starring Wang Baoqiang and E Jingwen, has been scheduled for release on New Year’s Day. On January 24th, Wang Baoqiang came to Hengdian with New king of comedy and visited the gathering place of extras. At the meeting, Wang Baoqiang connected the "drifting" family on the spot, hoping that the family would give them more encouragement and support, and encouraged the "drifting" people. "Although the process will be cruel, as long as you work hard and don’t surrender, you will be successful!"

  When Wang Baoqiang came to Hengdian this time, he recalled his career as an extra actor. He admitted that it was Yin Tianchou in king of comedy that supported him through the years of "walk-on". This year coincides with the 20th anniversary of the release of king of comedy, and I hope that the new king of comedy starring myself can bring some spiritual strength to today’s "drifters".

  At the first stop of Hengdian, Wang Baoqiang came to the training room of the Actors’ Guild to cheer up the new people who just came to Hengdian to be actors, share their experiences, and sent the first introductory lesson to pursue their dreams. "At first, it was the hardest. Without fame, we had to rely on our own efforts". Recalling his own struggle process, Wang Baoqiang said: "I am often hungry, but even if I am hungry, I have to print materials and run the crew." Facing the new "drifters", Wang Baoqiang said that he kept telling himself that the word "the masses" would be removed from the actors one day, and finally he succeeded.

  Wang Baoqiang also rushed to Hengdian Film and Television City, the shooting base, to give red envelopes and send blessings to the "drifting" who went to work. The "drifting" people are scrambling to learn from their predecessors. A "drift" who has been in Hengdian for seven years said: "I haven’t called home for a long time, for fear that my family won’t support me." Wang Baoqiang bluntly said: "You should always call your family to let them know that you are safe outside, and the encouragement and support of your relatives can make you go further and better." In the connection with another "drifting" relative, Wang Baoqiang said: "I hope you can give him more encouragement and support, and I hope that one day he can bring you a better life through his own efforts." Wang Baoqiang also said: "The walk-on road is very difficult, and many people don’t understand and support it. You can take your family and friends to the cinema to watch" New king of comedy "on the first day of the New Year’s Day, which is your hardship and difficulty. I believe that through intuitive understanding, your family and friends will feel your efforts and value."

  "Laughing with tears" is a major feature of Stephen Chow’s comedy films, and the struggle history of little people is the core of his films. Wang Baoqiang said: Although this is a "walk-on movie", no one is a small role. Everyone is a real actor and has their own bright spots. "This story is about the struggle of ordinary people. I believe everyone will get some positive and positive feelings, which can also bring you a lot of confidence and strength."

"Eavesdropping Wind and Cloud 3" exposes MV Liu Qingyun Gu Tianle singing the song of local tyrants

  The film is about to hit the big screen on May 29. The film is produced by Er Dongsheng and Huang Bin, co-directed by Mai Zhaohui and Zhuang Wenqiang, and starred by Liu Qingyun, Gu Tianle, Wu Yanzu, Zhou Xun and other powerful superstars. The gorgeous main cast can be said to have made the film popular before the film was released.
 
  Recently, the film released the MV for the theme song "Wind and Cloud" of "Eavesdropping on Wind and Cloud 3". In the film, the five members of the "New Territories Local Tyrant Alliance" Liu Qingyun, Koo Tianle, Fang Zhongxin, Lam Ka Tong and Lam Ka Wah formed the most powerful "Hong Kong Island’s No. 1 Men’s Sky Troupe" and turned into the lead singer of the group to perform together. Liu Qingyun, the "Captain" of the self-appointed band, introduced that the MV "Wind and Cloud" was the first single released after their team was established. "Although this song is an old song, it has been sung by a few of us local tyrants with a new feeling. It can be said that it has become a model of the’local tyrant song ‘in the new era."

After 30 years of old golden songs, Mai Zhaohui still leads the fashion, and uses "Wind and Cloud" to place his feelings
 
  The song "Wind and Cloud" was written by Gu Jiahui and composed by Huang Zhan. It was originally the theme song of the 1980 TVB TV drama of the same name in Hong Kong. The song was performed by Sendura that year and was widely sung. It became one of the golden songs of the 1980s in Hong Kong that cannot be ignored. Although it has been more than 30 years since the song was written, Liu Qingyun, Gu Tianle and other five people were still deeply moved by the lyrics of "Wind and Cloud" when they sang it. "In fact, every time I sing this song, I will feel a lot of feelings in my heart," Gu Tianle believes that "Wind and Cloud" is a song that can still lead the trend even today. "It talks about the changes in the vicissitudes of life and the unwavering emotion. These things will never go out of style."
 
  The two directors, Mai Zhaohui and Zhuang Wenqiang, also said that the reason why they chose an old song as the theme song of the movie was not only that the TV series that also talked about the land theme gave them a lot of creative inspiration, but also because "The Wind and Cloud" could place their most sincere feelings in their hearts. "In the era of globalization, people’s lives have changed greatly," Mai Zhaohui said. He often wonders whether he should stop and reflect on the past occasionally in the fast-paced present. "So in the movie, I used this song to express my nostalgia for the country, home and brotherhood." 
 
"The Strongest Sky Group on Hong Kong Island" group, the captain Liu Qingyun "Division of Labor" for Gu Tianle Fang CITIC
 
  In order to make this re-enactment of "Wind and Cloud" a new classic, Liu Qingyun, Gu Tianle, Fang Zhongxin, Lam Ka-tung and Lam Ka-wah formed a singing group on the set of "Eavesdropping Wind and Cloud 3" to form a singing group and complete the cover of the song together. Several local tyrants in the film joined forces, and this group was naturally "proud" and different. As the "chief local tyrant", Liu Qingyun declared domineering, "How can I find a group like us who are handsome and rich, can act and sing well? If we say we are the second-ranked boy band in Hong Kong, will anyone dare to claim the first position?"
 
  Due to his experience in singing theme songs with Gu Tianle and Zhang Jiahui, Liu Qingyun volunteered to be the captain of "The Strongest Men on Hong Kong Island" in "Eavesdropping 3", and also arranged the division of labor for the team members. "Gu Zai has already released records before, so I made him the lead singer," while Fang Zhongxin was appointed "image responsibility" by "Captain" Liu Qingyun for his cool "Beatles" style. "Brother Jiahua and Jiadong also sang very well," Liu Qingyun revealed that the five of them sang as well as their acting skills. "In" Eavesdropping 3 ", we played and sang again, and the wonderful guarantee was beyond imagination."

[World Talk] US media: It is difficult for the United States to make up for its "digital divide" by implementing global cyber hegemony.

  China Daily Online, September 21st According to comprehensive US media reports, the US Congress is moving towards the possibility that the government will shut down as early as next month. At present, there is no indication that the persistent differences between the two parties on the budget issue will end soon. At the same time, according to a report on the US Capitol Hill website on the 20th, the funds for an American Affordable Connectivity Program (ACP) aimed at ensuring that all Americans can connect to the fast Internet, thus narrowing the "digital divide" are expected to run out in the spring of 2024.

  Kathryn de Wit, the author of the article and director of the broadband access project of Pew Charity Trust Fund, pointed out that the two parties must find opportunities for cooperation without delay and bring tangible benefits to the public. One of the important projects is the ACP project, which was previously supported by politicians and voters of both parties. If the funds of this plan are allowed to dry up, millions of low-income families will suddenly lose the network connection that they now rely on for work, school and medical treatment. If the plan is stopped, the pockets of at least 20 million Americans will be immediately affected.

  According to previous reports, the United States has been monitoring the calls of European leaders all the year round, and the military leak incident has also exposed the large-scale monitoring of its allies by the United States, and it is even more "not to mention" to obtain user privacy data on social networks. The United States has a bad track record in the field of network security, and the "matrix" and "network hegemony" are worthy of the name. According to the data of the Federal Communications Commission, there are 8.5 million "unserved" areas and 3.6 million "underserved" areas in the United States.

  If the US Congress does not continue to provide funds for ACP after next spring, it means that the promise of broadband access in the Bipartisan Infrastructure Construction Act and other federal broadband plans will be broken, and the progress made over the years will come to nothing. According to a survey by the Digital Progress Institute, a bipartisan NGO, 78% of Americans support continuing to fund the program. But Congress did little to ensure that the plan continued.

  The New York Times reported on 19th that the lack and uneven distribution of high-speed Internet had a great impact on American people’s study, work and life. The article writes that due to the lack of high-speed internet service, residents in the southeastern edge of Oklahoma are distressed every day. Wanda Finley, a resident of Sawyer, the state, is a fourth-grade teacher. She said that the satellite service at home is often too slow to use, and sometimes it is even interrupted for several days. Before going to work, she can’t arrange medical appointments, apply for prescription refills or pay bills online. Almost every weekend, she has to drive to school for about 40 minutes to prepare lesson plans, because the internet speed at home can’t be loaded at all.

  The lack of broadband infrastructure is particularly serious in rural areas of the state, where Internet services are usually unavailable or limited. According to the definition of the new plan, about 24% of Americans in rural areas lack high-speed Internet service, while the proportion in urban areas is only 1.7%.

  However, Evan Feinman, director of the National Telecommunications and Information Administration’s $42.5 billion project (ACP), said that they believe that federal and state funds will be enough to cover every unserviced and underserved area.

  For Americans who lack high-speed internet access for a long time, the coverage of this fund will be crucial. Finley said that she wanted to assign more online research assignments to speed up her study. But among the 20 students in her class, only three students have enough internet access at home, and the rest can’t finish it.

  A few miles away, there are about 600 residents in Towsenburg, Oklahoma. The mayor Tami Barnes said that the slow internet speed has had a "great impact" on the local economy. Although online bills have added a burden to many families, if there is a high-speed internet, more residents may see a doctor through the internet, instead of spending three hours to see a specialist.

  Other states with low population density, such as Montana, may also face more challenges. In broadwater County, Montana in the northwest, many families are separated by large grasslands, while others are located in mountainous areas. Residents say it is difficult for them to work from home because of the lack of quick service. In southeastern Florida, many people still lack reliable broadband access. The U.S. Census Bureau even pointed out that among the 10 counties with the lowest per capita income in the state, 7 counties have the lowest broadband access rate. According to recent data, the number of registered ACP programs in Florida is about 1.4 million, accounting for 38% of eligible families in the state.

  According to the related report of The Minnesota Daily)19 website on 19th, most of the courses of the University of Minnesota are completed through Canvas, which requires the internet to access. Students who live in the campus can use the free network of the university, but many students who live in off-campus dormitories cannot access the internet, and the internet cost is very high.

  According to the data of American Midwest Higher Education Compact, 16% to 19% of students lack Internet-related assets. Baraka Aswan, a sophomore who lives off campus, said that they had considered reducing water and electricity bills through the ACP plan. Aswan shared a room with friends. He said that in the first week of college, his house could not use any wireless network, which made their first few days back to school very difficult. Aswan added that cheaper Internet can leave more room for other expenses such as groceries and rent.

Future food, "nutrition" and a better life (open books to learn new things)

Core reading
Based on biotechnology and bio-industry, food in the future is expanding to richer biological resources, requiring heat and protein from plants and animals. The development trend of food in the future is the high integration of food technology, biotechnology and information technology.
In his important speech at the Central Rural Work Conference, General Secretary of the Supreme Leader stressed: "We should establish a big food concept, build a diversified food supply system and develop food sources in multiple ways." Bread is the staff of life. With the rapid development of economy and society and the continuous improvement of people’s living standards, China’s food consumption has shifted from full to good, and it is increasingly pursuing healthy and happy eating. At the same time, population growth, climate change, resources, environment, public health and many other complex factors pose great challenges to the sustainable supply and nutritional health of food in the future.
The "big food concept" has defined the direction for the high-quality development of food technology and industry in the future. To deeply grasp the changing trend of food structure and meet people’s needs, we should ensure food supply in quantity, improve the function and nutrition of food in quality, change the traditional food supply mode that depends entirely on planting and breeding, develop food resources in all directions and in many ways, and realize the diversification of food sources. Based on biotechnology and bio-industry, food in the future is expanding to richer biological resources, requiring heat and protein from plants and animals.
Develop more nutritious, delicious, safer and sustainable future food.
How will human food in the future be different from today? This is a problem that people are concerned about, and it is also a subject that scientists are exploring unremittingly. Future food is the development of traditional food and modern food, which embodies the change of future production methods and lifestyles. The main task is to solve the problems of food supply and quality, food safety and nutrition, diet and spiritual enjoyment. From the perspective of scientific development, based on synthetic biology, Internet of Things, artificial intelligence, additive manufacturing and nanotechnology, food will be safer, more nutritious, more delicious and more sustainable in the future.
As a high-tech industry, the future development trend of food is the high integration of food technology (FT), biotechnology (BT) and information technology (IT). Compared with today’s food industry, the future food industry has three main characteristics.
The first is to change the manufacturing mode of the traditional food industry. Different from planting and breeding, in the future, food can be made into meat, eggs, milk, oil and other foods by combining food with biotechnology, making the food production mode more efficient, green and sustainable. For example, soybean and other plant proteins are used as raw materials to obtain plant protein meat through extrusion and texturing, or muscle stem cells are extracted from animals, which are expanded and cultured into muscle cells, and then differentiated into muscle fibers to form cell culture meat. These technologies are gradually maturing.
The second is to make people healthier and the earth healthier. A reasonable diet is very important to our health, and a bad diet may lead to health problems. Medical research shows that adding certain plant protein to food structure instead of animal protein is beneficial to health. It is the representative development direction of food in the future that plant protein replaces animal protein. Different from the traditional way of obtaining animal protein by livestock and poultry breeding, the future food will obtain protein by means of plants and microorganisms, which will produce less greenhouse gases, occupy less cultivated land, be more efficient and environmentally friendly in terms of resource consumption and environmental impact, and make the earth healthier.
The third is to be able to cope with the food challenges facing mankind. According to relevant statistics of the United Nations, the global demand for protein will greatly increase by 2050. Therefore, improving the production efficiency of food protein and seeking alternative protein have become an important topic for food in the future. The protein obtained by animal cell culture, microbial fermentation and plant cultivation not only has obvious advantages in production efficiency, but also can meet the needs of different food protein functions and properties more easily.
Explore new possibilities of food in the future through scientific and technological innovation
In the future, food has broad prospects in basic research and frontier technology innovation, key common technology development, systematic product manufacturing, industrial chain technology integration and so on, and has achieved certain results. Plant-based food and substitute protein are typical representatives, reflecting the important trend of food science and technology innovation and future food industry development.
Plant-based food is a kind of food with texture, flavor, shape and other characteristics similar to animal food, which takes plant raw materials or its products as the source of protein, fat and so on, with or without other ingredients. In layman’s terms, it is a new type of food with similar taste to meat, eggs and milk with plants such as soybeans, peas and wheat as the main raw materials through processing. Plant-based foods can be divided into plant-based meat products, plant-based dairy products and plant-based egg products. People are familiar with traditional vegetarian foods such as vegetarian chicken and duck, which are the primary forms of plant-based meat products. However, plant-based foods are significantly different from traditional vegetarian foods in reducing the intake of saturated fatty acids and cholesterol and providing high-quality protein. In recent years, plant-based meat products have been applied in hamburger stuffing, and domestic enterprises have jointly launched whole plant beef, pork and other products that meet the taste of China population, and their shape, flavor and taste are closer to traditional meat products. Oat milk, almond milk and other products on the market are typical plant-based dairy products with the characteristics of low calorie, low fat and high dietary fiber.
With the breakthrough of design and manufacturing technology, especially the application of synthetic biology technology and advanced manufacturing equipment, plant-based food will become more nutritious and healthy. Taking plant meat as an example, by changing the structural characteristics of plant protein, adding hemoglobin, glutamine transaminase, vitamins and other substances, and using technologies such as hemoglobin synthesis and scientific compounding, plant meat not only has almost the same appearance, color and taste as traditional meat, but also has more reasonable amino acid composition and is easier to digest, which can reduce the intake of salt, sugar and oil and provide more choices for people’s healthy lifestyle.
Substitute proteins involve emerging protein industries such as microbial fermentation proteins and microalgae proteins. We often hear the suggestion of "supplementing protein". The scientific reason behind this is that food protein is an important nutrient for human beings, which has the functions of constructing and repairing human tissues, transporting various substances, maintaining nervous system function and providing energy. Innovative development of sustainable and high-quality protein production methods has become one of the key directions of food research in the future. Substitute proteins came into being.
Among the substitute proteins, microbial fermentation proteins are representative. With the help of biotechnology, microorganisms are programmed to convert raw materials into protein needed by human beings through specific metabolic pathways. The efficiency of protein synthesis is thousands of times that of traditional aquaculture, and it can significantly improve the efficiency of protein production and reduce carbon dioxide emissions. It is pointed out that if microbial protein replaces 20% of the global beef consumption by 2050, it is estimated that the global annual carbon dioxide emissions will be reduced by 56%, and the amount of deforestation will also be reduced. In the production and application, there has been a workshop to obtain high-quality protein with high fiber and low saturated fat by Fusarium oxysporum fermentation. The fermentation tank with industrial scale of 165 cubic meters can produce 250,000 sausages at a time. In addition, microbial fermented protein has certain advantages in nutrition, taste and so on. For example, yeast protein contains all the essential amino acids of human body, which is a complete protein with rich nutrition, can meet the nutritional needs of human body, has no beany smell and no allergenic components, and is suitable for a wide range of people.
There are three synthetic processes of microbial fermentation protein. Firstly, starch resources (such as corn) are used as raw materials, and sugar which can be used for fermentation is obtained through microbial liquefaction and saccharification, and then used as substrate for cell growth and protein synthesis. This method has the characteristics of mature raw material treatment process and stable fermentation process control. Second, organic wastes generated in production and life are used as raw materials. This method has low raw material cost, realizes the recycling of wastes and promotes the development of circular bio-economy. Thirdly, carbon compounds are directly used as raw materials, such as carbon dioxide, methanol or methane, which are rich in nature, as substrates, to create a microbial cell factory with efficient coordinated metabolism and transformation of carbon and nitrogen, complete the transformation from carbon compounds and inorganic nitrogen to microbial protein, and finally realize the efficient and green manufacturing of microbial protein.
Food is closely related to human survival and development. Behind the delicious food, the strength of food technology is condensed. Under the guidance of the "big food concept", researchers are exploring new possibilities of food in the future, contributing scientific and technological strength to ensure the self-control of China’s food industry chain and building a diversified food supply system, striving to achieve high-level self-reliance and self-reliance in China’s food science and technology, promoting residents’ nutrition and health, and creating a better "China on the tip of the tongue".
