bulk Nisin for food processing

Nisin (CAS 1414-45-5) is a natural antimicrobial peptide produced via fermentation by Lactococcus lactis, consisting of 34 amino acid residues. As a globally recognized safe, highly efficient, non-toxic natural food preservative (INS No. E234, GRAS certified), Nisin effectively inhibits the growth of most Gram-positive bacteria and their spores. It is widely used in meat products, dairy products, canned food, beverages, condiments and other food industry segments. In 1969, the Joint FAO/WHO Expert Committee on Food Additives (JECFA) officially confirmed the safety of Nisin for food application. In 1992, the Ministry of Health of the People's Republic of China formally approved Nisin as a legal food preservative. As a source manufacturer, we supply high-purity, high-activity Nisin products with stable bulk supply capacity for global customers.
