There are different types of preservatives, and the principle of anti-corrosion is different. The first one is the enzyme system that interferes with microorganisms, destroying its normal metabolism and inhibiting activity; the second is to coagulate and denature the proteins of microorganisms. Interfering with its survival and reproduction; the third is to change the permeability of the plasma membrane, inhibit the elimination of enzymes and metabolites in the body, leading to its inactivation.
When it comes to preservatives, people tend to pay more attention to their side effects. In fact, as long as they are safely used, they have no toxic side effects on the human body. As an agent that inhibits spoilage of a substance, it has a sustained inhibitory effect on the growth of a microorganism that uses a spoilage substance as a metabolic substrate. What is important is that it inhibits the most prone to spoilage under different conditions, especially when the general sterilization effect is insufficient.
The so-called preservative, its main function is to inhibit the growth and reproduction of microorganisms, which has a killing effect on the microbial propagules, and the spores can not develop into a propagule and gradually die. Of course, the action mechanism of different preservatives is not exactly the same.https://www.china-zhufengchem.com/
