Lactic acid peptide (Nisin) also called lactic streptococcus streptococcus element or transliteration as solzhenitsyn, is a kind of polypeptide produced by lactic acid streptococcus material, is composed of 34 amino acid residues, the molecular weight is about 3500 Da. Due to streptococcus inhibits most gram-positive bacteria, and the spores of bacillus had strong inhibitory effect, therefore was used as a food preservative is widely used in food industry. After eating in the body's physiological pH conditions and under the action of alpha - chymotrypsin hydrolysis into amino acids, soon will not change the human intestinal normal flora and produce as other antimicrobial resistance problems, not other antibiotics and cross resistance, is a highly efficient, non-toxic, safe, no side effects of natural food preservatives

Used in meat products, dairy products, canned, seafood, drinks, juice drinks, liquid egg and egg products, spices, wine making, baking food, convenience food, sweet spices, cosmetics, etc.
