Three stages

Food processing industry has a long history of development. Food industry refers to an industrial system with continuous and organized economic activities, which takes the products or semi-finished products of agriculture, fishery, animal husbandry, forestry or chemical industry as the main raw materials and is manufactured, extracted and processed into food or semi-finished products. With the continuous progress of science and technology, the modern food industry is developing rapidly, the scope and depth of food processing are expanding, and the science and technology used are becoming more and more advanced.

China's food industry started late, and residents' food consumption has always been dominated by direct consumption of agricultural products. The food industry in China has developed by leaps and bounds, and its development has mainly gone through three stages.

First, steady and slow growth At this stage, China's food industry is in an "import" state.

At present, the development of China's food industry is relatively slow, the labor rate of the whole industry is relatively low, the technical production level is heavily dependent on foreign imports, and the absorption level of imported technology is also very low. On the other hand, influenced by the national development policy, heavy industry is neglected and insufficient attention is paid to the development of food industry.

Second, the awakening stage of food industry.

From 65438 to 0978, China carried out reform and opening-up, and its economy showed a comprehensive revitalization trend. Reform and opening up have brought opportunities for the development of food industry and promoted the introduction of advanced technology. However, due to "a long illness is difficult to heal, and it is difficult to return to the past", the rapid development momentum did not break out in the beginning of the year. Two years later, the technology introduction and new investment in the food industry began to play a role, that is, from the 1990s, the food industry in China showed an awakening trend, and the overall development level suddenly reached a new level.

Third, the rapid development stage of food industry.

2 1 century, China has gradually attached importance to the development of food industry in policy, especially in the Tenth Five-Year Plan, which has increased policy support and financial support for scientific research and development of food industry, making the development of China's food industry show a steady and rapid development trend. Since 2003, the development speed of China food industry has been significantly higher than the previous stage, with an average annual growth rate of 20.44%. On the existing basis, the annual output value has increased by more than 400 billion yuan. Judging from the growth of total output value of food industry, the development of food industry in China has reached a new level. With the development of national economy and the improvement of people's living standards, people put forward higher requirements for food industry. Modern food has developed towards nutritious, green, convenient and functional food.
