Preservatives are used to keep food original quality and nutritional value for the purpose of food additive, it can inhibit the growth of microbial breeding, avoid food decaying and prolong shelf life.Corrosion principle of preservatives, roughly the following 3 kinds: one is interference of microbial enzymes, destroy the normal metabolism, inhibit the activity of enzyme.2 it is to make the microbial protein coagulation and degeneration, interfere with its survival and reproduction.3 it is to change the permeability of cell size, inhibit the body's enzymes and metabolic product of exclusion, causes the deactivation preservatives are used to keep food original quality and nutritional value for the purpose of food additive, it can inhibit the growth of microbial breeding, avoid food decaying and prolong shelf life.Corrosion principle of preservatives, roughly the following 3 kinds: one is interference of microbial enzymes, destroy the normal metabolism, inhibit the activity of enzyme.2 it is to make the microbial protein coagulation and degeneration, interfere with its survival and reproduction.3 it is to change the permeability of cell size, inhibit the body's enzymes and metabolic product product out, cause its inactivation
