Abstract: The effect of electric field on the fresh-keeping effect of refrigerator fruits and vegetables was studied, and the optimal field distribution area of fruit and vegetable preservation was explored. The experimental results show that the electric field environment of the refrigerator has a significant effect on the storage loss, respiratory intensity and color change during the storage of rapeseed and tomatoes. In general, the second layer of the electric field refrigerator fresh-keeping layer (S2, about 40cm away from the electric field preservation power supply, the electric field intensity distribution range is about 50~300v/m), the sample has the best fresh-keeping effect, and is more suitable for storing fruits and vegetables in a short period of time.
