Nisin, also known as nisin or transliterated as Nisin, is a polypeptide substance produced by nisin. It consists of 34 amino acid residues and has a molecular weight of about 3500 Da. Since nisin can inhibit most Gram-positive bacteria and has a strong inhibitory effect on the spores of Bacillus, it is widely used in the food industry as a food preservative. After eating, it is quickly hydrolyzed into amino acids under the physiological pH conditions of the human body and the action of α-chymotrypsin, which will not change the normal flora in the human intestine and produce resistance problems such as other antibiotics, and it will not interact with other antibiotics. It is a natural food preservative with high efficiency, non-toxicity, safety and no side effects due to cross-resistance.
