Polylysine Introduction
Polylysine (ε-poly-L-lysine) is a natural food preservative produced through natural fermentation using the bacteria Streptomyces and more specifically Streptomyces albulus under aerobic conditions . Polylysine consists as a small natural homo-polymer (25-30 L-lysine residues) of the essential amino acid, L-lysine. Its application includes cakes, rice, cheese and other dairy foods and meats.
A dvantages
1. Broad antibacterial spectrum: it has obvious inhibition to gram-positive bacteria and gram-negative bacteria, yeast, mould, virus and many other micro-organisms.
2. Good thermal stability: below high temperature ( 120 o C for 20 min ) . Polylysine does not decompose, nor experience inactivation, and is suitable for cooked food.
3. Good water-solubility: Polylysine has good water-solubility, Polylysine spreads evenly in food; colorless, odorless and natural, does not affect overall food flavor.
4. Wide pH range: broad anti-bacterial spectrum (pH 2 to 9), to supplement the weakness with most common preservatives; poor effects in neutral and alkaline conditions.
5. Strong blends: As a natural preservative, ε- PL can be used alone. In addition, it has a synergistic effect when blending with Potassium Sorbate, Citric acid, Malic Acid, Glycine and Nisin. After blending, its bactericidal action will be improved greatly.
6. Safe for human consumption: after eating, Polylysine does not accumulate inside the human body. It partly breaks down into L-lysine, an essential amino acid for human health. L –lysine is non-toxic, and known as th e "pharmaceutical & nutrient preservative".
7. Health function: Recent studies show that ε-Polylysine can inhibit the enzyme activity and the
fat absorption in the small intestine ester, has curative effect against, with obesity.
