Nisin Introduction
Nisin is a natural polypeptide food preservative produced through fermentation by Lactococcus lactis. Nisin has good antibacterial activity against a wide range of Gram positive bacteria and their spores, especially for heat resistant bacilli, such as Bacillus stearothermophilus,
Clostridium butyricum and Listeria monocytogenes. It also shows inhibition activity against some Gram negative bacteria under certain conditions.
Nisin is a natural food preservative which is highly efficient, safe and has no side-effects. Nisin was awarded the Generally Regarded as Safe
(GRAS) designation in the U.S. Federal Register and is approved as a natural food preservative in the U.S., the FAO/WHO and the E.U.
Advantages
Extend product shelf-life
Improve safety a variety of foods by suppressing Gram-positive spoilage and pathogenic bacteria（replace chemical preservatives）
Cost effective，high efficiency at low dosages
Enable reduced processing timeshare and temperature
Useable in fermented products (No effect on bacteria)
Reduced heat treatment and processing times
Suppresses post-acidification in cheese
No apparent cross-resistance related to therapeutic antibiotics
Stable heating at low pH

Direction of Usage:
Safety
Nisin is non-toxic, the producer strains of L. lactis are regarded as safe (food-grade); it is not used clinically; there is no apparent cross-resistance in bacteria that may effect antibiotic therapeutics; and it is quickly digested into amino acids by enzymes in human intestines and stomach.
ADI: 33000 IU/kg (FAO/WHO, 1994)
