What are the preservative principles of preservatives?
Preservatives are a kind of food additives that can inhibit microbial activity and prevent food spoilage. In order to make the food have a certain storage period, certain measures must be taken to prevent the infection and reproduction of microorganisms. The practice of preservative manufacturers has proved that the use of preservatives is one of the most economical, effective and simple ways to achieve the above purposes.
The anti-corrosion principle of preservatives is roughly as follows:
First, it interferes with the enzyme system of microorganisms, destroys their normal metabolism, and inhibits the activity of enzymes.
Second, it makes the protein of microorganisms coagulate and denature, interfering with their survival and reproduction.
Third, it changes the permeability of the serous membrane of the cell, inhibits the exclusion of enzymes and metabolites in the body, resulting in its inactivation.
