Abstract

Abstract: Taking blueberries, cherries, colored peppers, okra, fresh-cut apples and fresh-cut lotus roots as experimental objects, by measuring the Vitamin C content, anthocyanin content, total phenolic content, sensory score and total number of bacterial colonies, the quality changes of fruits and vegetables in the magnetic field fresh-keeping compartment and ordinary fresh-keeping compartment of the refrigerator were studied. The results showed that the loss of Vitamin C content in blueberries, cherries, bell peppers and okra was less in the magnetic field fresh-keeping compartment. The degradation of anthocyanin in blueberries and cherries was slower; the total phenolic content and sensory quality were decreased flatly, and the growth of the total number of colonies was inhibited. From the perspective of various indicators, the shelf life of fruits and vegetables under the condition of magnetic field refrigeration in the refrigerator was longer, and the preservation effect was significantly better than that of ordinary refrigeration.

Key words: Fruits and vegetables, Cold storage, Magnetic field, Fresh-keeping
