Abstract: This paper discusses the development trend of deep processing technology of fruits and vegetables and drying technology of new fruits and vegetables. The characteristics of vacuum freeze drying, microwave drying equipment and vacuum frying drying technology are compared. Finally, the characteristics of variable temperature and temperature differential expansion drying technology and the development trend at home and abroad are introduced. It is expected to provide some reference for the research and development of fruit and vegetable drying technology.
Key words: microwave drying of fruits and vegetables; drying technology; temperature difference
At present, countries such as the United States, Western Europe and Japan use fresh fruit and vegetable juices to formulate or process fruit juice beverages, which have a good effect on maintaining normal metabolism, preventing disease and inhibiting the formation and development of cancer cells. The results of modern epidemiological studies have confirmed that the intake of fresh fruits and vegetables is negatively correlated with the incidence of cancer.
