The reason why blueberries are processed and sold is that a large number of blueberries in the market are difficult to be digested by the market in a short time, and there are more and more processed blueberries. The planting area of blueberries is getting larger and larger, and the output is increasing. The added value of blueberries can be improved through deep processing, and the economic benefits of blueberries can be greatly improved by commercialization after harvest, and the price can be increased several times. Deep-processed blueberry food is located in the downstream of the industrial chain, which can exist independently of the main blueberry producing areas, providing favorable conditions for the overall development of the blueberry market.
