描述

Nisin is a polypeptide antibiotic substance produced by Streptococcus lactis, consisting of 34 amino acids. When it enters the human body, it will be decomposed into various amino acids by enzymes, leaving no residue, no drug resistance, and no effect on human probiotics. It can effectively inhibit the growth and reproduction of many Gram-positive bacteria that cause food rot, especially has a strong inhibitory effect on heat-resistant Bacillus, Clostridium botulinum and Listeria. It is a natural food preservative that is toxic, safe, and has no side effects, and has good solubility and stability.
