Core reading Future food is based on biotechnology and bio-industry, and is expanding to more abundant biological resources, requiring heat and protein from plant and animal microorganisms. The development trend of food in the future is the high integration of food technology, biotechnology and information technology. With the rapid economic and social development and the continuous improvement of people's living standards, China's food consumption has shifted from being full to eating well, and the pursuit of eating healthily and happily is increasing. At the same time, population growth, climate change, resources, environment, public health and other complex factors pose great challenges to the sustainable supply of food and nutritional health 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 understand the changing trend of food structure and meet the needs of the people, it is necessary to guarantee the food supply in quantity, improve the function and nutrition of food in quality, change the traditional food supply mode completely relying on planting and breeding, develop food resources in an all-round and multi-channel way, and realize the diversification of food sources. Based on biotechnology and bio-industry, food in the future is expanding to more abundant biological resources, requiring heat and protein from plant and animal microorganisms. Develop a more nutritious, delicious, safe and sustainable future food. How will the future food of mankind be different from today? This is a matter of concern to the people, and also a subject that scientists are constantly exploring. Future food is the development of traditional food and modern food, reflecting the change of production methods and lifestyle in the future. Its 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, the Internet of Things, artificial intelligence, additive manufacturing, nanotechnology and other technologies, food will be safer, more nutritious, more delicious and more sustainable in the future. As a high-tech industry, the development trend of food in the future 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. First, change the manufacturing mode of traditional food industry. Unlike planting and breeding, the future food can produce meat, eggs, milk, oil and other foods in the industrial workshop production mode through the combination of food and biotechnology, making the food production mode more efficient, green and sustainable. For example, using soybean and other plant proteins as raw materials, plant protein meat can be obtained through extrusion and tissue, or muscle stem cells can be extracted from animals, 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 structure is crucial to our health. Bad diet may cause health problems. Medical research shows that adding certain plant protein to the food structure to replace animal protein is beneficial to health. Replacing animal protein with plant protein is the representative development direction of food in the future. Different from traditional livestock and poultry breeding to obtain animal protein
