Product Description
Biological natural preservatives in medicines
ε-polylysine is a naturally produced, cationic homopolymer of 25-35 L-lysine(due toStreptomyces albulus fermentation.), which was connected by ε-amido bond compounded by a ε-amido of l-lysine and a a-carboxyl of another l-lysine.
Advantages
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 (120oC 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 the "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.
