[ The character of Nisin ]
  Since Nisin (also known as Streptococcus 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 causes food spoilage, and especially inhibits 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.
