nisin e234

1. Nisin

Nisin, CAS 1414-45-5, E234, molecular formula C143H230N42O37S7, molecular weight 3354.0705.

It is a polypeptide produced by Streptococcus lactis, consisting of 34 amino acid residues, which is quickly hydrolyzed into amino acids under the action of human physiological pH conditions and α-tryptic rennet, and will not change the normal flora in the human intestinal tract and produce resistance problems such as other antimicrobials, not to mention cross-resistance with other antimicrobials, and is a highly effective, non-toxic, safe and non-side effect natural food. It is a natural food preservative with high efficiency, non-toxic, safe, and has no side effects.

Since nisin can inhibit most gram-positive bacteria and has a strong inhibitory effect on the spores of Bacillus, it is widely used as a food preservative in the food industry.

2. Mechanism of action of nisin

Nisin is a hydrophobic, positively charged small peptide, which can adsorb on the cell membrane of Gram-positive sensitive bacteria and interact with negatively charged substances in the cell wall (such as phosphopeptide, glyoxylate, acidic polysaccharide, or phospholipid), and can invade into the cell membrane through the C-terminus to form a permeable pore, inhibit the synthesis of the cell wall of Gram-positive bacteria, change the permeability of the cell membrane, and cause the small molecules in the cell At the same time, the influx of extracellular water molecules causes the cell to die by autolysis.

3. Application scope of nisin

It can be widely used in meat products, dairy products, canned food, seafood, beverages, juice drinks, liquid eggs, and egg products, spices, brewing process, baked food, convenience food, fragrance-based spices, cosmetic field, etc.
