Nisin is a polypeptide antibiotic secreted by nisin and consists of thirty-four amino acids. Using yeast powder as raw material, it is fermented by lactic streptococcus under certain conditions. The fermentation broth is acidified, concentrated, filtered, salted out, and spray-dried after steam sterilization to obtain the finished product.

Product Application

Nisin is a natural anti-microbial agent used as a preservative in heat-processed and low-pH foods. Its anti-microbial activity is used against a wide range of gram-positive bacteria and their spores, which cause food spoilage. It especially inhibits heat-resistant bacilli, such as B.Stearothermophilus, C. Butyricum, and L. monocytogenes. Nisin alone is not effective against gram-negative bacteria or yeasts and molds. Research has shown that Nisin in combination with chelating agents such as EDTA or nonionic surfactants such as Polysorbate 20, shows potent bactericidal activity against gram-negative organisms.
