Introduction:
Nisin to lactic acid streptococci secreted peptide antibiotics, made up of 34 amino acids. Using yeast as raw material, under certain conditions, nisin fermentation. Fermentation broth by acidification after steam sterilization, concentration, filtration and fractionation and spray-dried products.
It is white crystalline powder. It tastes salty and it’s easily deliquescence. Relative density is 1.570. Melting point is 292℃. It’s easily soluble in water, ethanol and carbinol, but insoluble in aether.
Nisin, a peptide with 34 amio acids, can be digested into a variety of amino acids by proteinases on entering the human body with out residue. It does not develop any drug resistance or influence human probiotics, but effectively inhibit the groth, reproduction of many Gram positive bacteria, Clostridium botulinum and listeria.
Usuage:
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.
