Nisin (also known as Str. lactic peptide) is a polypeptide; it is rapidly inactivated in the intestine by digestive enzymes after consumption. Extensive micro-biological tests have not shown any cross resistant between nisin and medical antibacterial drug.
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. It is a natural food preservative which is highly efficient, safe and has no side-effects. In addition, it has excellent solubility and stability in food. It is not effective against Gram-negative bacteria, yeasts or mould.
