Abstract

The invention provides a food fresh-keeping system, which comprises an electrode device connected with an alternating-current power supply and to-be-stored food and used for forming a high-voltage electric field area, and the to-be-stored food is placed in the high-voltage electric field area. An electric field formed by the electrode device can induce polar molecules in the to-be-stored food to vibrate, the time for food materials to pass through the maximum ice crystal growth zone can be effectively shortened, the cell sap leakage is reduced, the freezing and thawing quality is improved, thehigh-voltage electric field can also improve the antioxidant enzyme activity in the to-be-stored food, the permeability of cell membranes is influenced, the long-term fresh-keeping effect is achieved, and the storage time of the to-be-stored food is prolonged.

Description

technical field [0001] The invention relates to the field of fresh-keeping of agricultural products, in particular to a food fresh-keeping system. Background technique [0002] After plants (including vegetables, fruits, etc.) are picked out of their original environment, they will face external stress from temperature, pressure, and humidity no matter they are stored in any environment, which will cause the accumulation of active oxygen and lead to peroxidation of membrane lipids, forming propane Aldehyde (MDA). MDA has a strong destructive effect on the plasma membrane and many biological functional molecules in the cell. It attacks the unsaturated fatty acids in the membrane lipid bilayer, damages the membrane system, and causes damage to the plant. It can interact with the membrane lipids. Protein amino acid residues or nucleic acid react to produce Shiff base, thereby reducing membrane stability, increasing membrane permeability, promoting membrane leakage, disordering...
