Nisin is a food preservative which is well-known around the world.
Vegetal Nisin, two natural types of Vegetal NisinA and Vegetal NisinZ, from Handary is made by fermenting the sauerkraut bacteria of Lactococcus lactis R5 andLactococcus lactis 22186. They have a similar structure but differ in a single amino acid residue at position 27;histidine in Vegetal Nisin A and a***ragine in Vegetal Nisin Z.
Both types of Vegetal Nisins are effective against Gram-positive bacteria and has also been shown to be effective against Gram-negative bacteria when applied as part of the hurdle technology approach (simultaneous application of several processes or barriers) to food safety and preservation. Since 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 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.
