Nisin is a food preservative which is well-known around the world
 

Features: 
1) Since nisin (also known as Str. lactic peptide) is a polypeptide, it is rapidly inactivated in the intestine by digestive enzymes after consumption

2) Extensive micro-biological tests have not shown any cross resistant between nisin and medical antibacterial drug

3) Nisin possesses anti-microbial activity against a wide range of Gram-positive bacteria and their spores which cause food spoilage, and especially inhibit the heat-resistant bacilli, such as B. Stearothermophilus, CI. Butyricum and L. Monocytogenes

4) It is a natural food preservative which is highly efficient, safe and has no side-effects

5) In addition, it has excellent solubility and stability in food. It is not effective against Gram-negative bacteria, yeasts or mould
