Fruit and vegetable processing is processed through various processing technologies, so that it can be preserved for a long time, durable and edible at any time. Zui should preserve its nutritional components to a greater extent in the processing process, improve its edible value, make the processed products have complete color, flavor, more reasonable tissue morphology, and further improve the commercialization of fruit and vegetable processing products.

Our country is rich in fruit and vegetable resources. Among them, the annual output of nearly 70 million tons of fruit and vegetable products reaches about 500 million tons, ranking the first in the world. Fruit and vegetable industry is the second largest agricultural industry in China after food crops. The total output of fruits and vegetables in China is expected to reach 100 million tons and 600 million tons respectively by 2010. Fruits and vegetables are rich in resources, providing sufficient raw materials for the fruit and vegetable processing industry.

As an emerging industry, fruit and vegetable processing industry plays an increasingly prominent role in China's agricultural and rural economic development. It has become the main economic source and new economic growth point of China's rural areas and farmers. It has become an agricultural industry with regional characteristics and export potential and a pillar industry of China's agriculture.    

Based on the current fruit and vegetable yield and post harvest loss rate in China, if the fruit loss is reduced by about 15% after delivery, it is equivalent to increasing 10 million tons of fruits and vegetables and expanding the orchard area of 667000 mu; If the loss of vegetables is reduced by 10% after delivery, it is equivalent to an increase of 45 million tons of fruits and vegetables; If the fruit loss is about 10% after delivery, it is equivalent to increasing the direct economic benefits of 1.334 million tons of fruits and vegetables; If the fruit loss is reduced by about 10% after delivery, the direct economic benefit of 30 billion yuan can be increased.

It can be seen that, in view of China's current advantageous and characteristic agricultural industry, actively developing the fruit and vegetable processing industry can not only greatly improve the postpartum added value and enhance the export foreign exchange earning capacity, but also drive the rapid development of relevant industries, absorb a large number of rural surplus labor force, increase employment opportunities, and promote the healthy development of local economy and regional agricultural industry. It is of great strategic significance to fundamentally solve the "three rural" problems of agriculture, farmers and rural areas, increase farmers' income and agricultural efficiency, and promote the sustainable development of rural economy and society.

At present, China's fruit and vegetable production has begun to form a more reasonable regional distribution. After further strategic adjustment of industrial structure, especially accelerating the development of the western region, the "West shift" of China's fruit and vegetable industry has appeared. We will seriously grasp the opportunity of "fruit and vegetable industry transfer", actively promote the development of fruit and vegetable processing industry in the western region and promote the economic development of the western region.
