Abstract
The invention achieves control over mixing controlled atmosphere storage of fruit vegetables by preparing an air-conditioned cold store, selecting fruits and vegetables, precooling, and stacking. Fruits and vegetables, upon pickup. are precooled to 9-11° C. in a vacuum pre-cooler for 12-24 hours. They are then stacked in a controlled atmosphere storage house. O2, CO2, N2 and Ar with different proportions are used for modified atmosphere packaging. The invention can extend the storage of mixing storage of various kinds of typical fruits and vegetables to more than 50 days, during which the fruits and vegetables are maintained in good color and flavor and have higher peroxidase, superoxide dismutase, catalase and cellulose activity; also, accumulation of hazardous substances such as superoxide anion free radical, hydrogen peroxide and malonaldehyde is effectively reduced, the retention rate of Vc is up to 80%-90%, and the weight loss ratio can be controlled to be below 8%.
