About half of consumers think canned food contains preservatives, according to a survey of nearly 6,000 consumers conducted by the Canning Association of China. It is not fresh, and the more educated the consumers, the deeper the misunderstanding, which has affected the development of canning profession.

Liang Zhongkang, chairman of China canning Association, said that canned food refers to a kind of food that reaches commercial asepsis by thermal sterilization after being canned and sealed, and does not need to increase preservatives. Besides, at present, the food produced by China's canning production line is mainly used for export. Japan, North America, Europe and other developed countries are the primary importers of cans, so their safety standards are becoming more severe and harsh. Therefore, in the production process and management level, canning enterprises are very strict control. Can not only peel to nuclear, eliminate the residual pesticide on the skin, making cans sealing, high temperature heat treatment and vacuum preservation technology, reach the sterilization effect is the most complete, therefore canned fruit base don't need to add any preservatives, completely depends on the container seal and high pressure sterilization of food save don't change for a long time, The high vacuum in the container keeps the flavor and nutrients of the food to the utmost.
