Product Description

What is Poly-L-Lysine?

Polylysine (ε-poly-L-lysine, EPL) is a small natural homopolymer of the essential amino acid L-lysine that is produced by
bacterial fermentation. ε-Poly-L-lysine is used as a natural preservative in food products.ε-Polylysine belongs to the group of cationic polymers. In water, ε-polylysine contains a positively charged hydrophilic amino group . According to research, ε-polylysine is adsorbed electrostatically to the cell surface of the bacteria, followed by a stripping of the outer membrane.This eventually leads to the abnormal distribution of the causing damage to the bacterial cell.
ε-Polylysine is recognized as a very safe substance in the scientific community. ε-Polylysine was generally recognized as safe as food preservative in October, 2003.It had been approved for use as an antimicrobial agent in cooked rice or sushi rice at levels up to 50 milligrams per kilogram (mg/kg) of rice. The results of an acute toxicity study and bacterial assays for mutagenicity shows that ε-Polylysine was non-toxic and there was no evidence for mutagenic activity of ε-Polylysine. So ε-Polylysine is absolutely safe to be used as food preservative.

Function of Poly-L-Lysine:

 

* 1. Epsilon-Polylysine can greatly inhibit the growth of bacteria, yeasts and moulds bacteria, especially to the Gram- bacteria which can not easily inhibit by others.
* 2. As a good preservative, Epsilon-Polylysine is characterized as being high safety, water-soluble, stable at high
temperatures, widely usage, non prejudice to the taste, antibacterial in neutral or subacidity conditions.
* 3. Because of the stability at high temperatures, it can inhibit some heat-resistant bacillus after heat treatment and some tadpole-form noncontractile siphovirus as well.
* 4. Epsilon-Polylysine can stop small intestine fat absorption through inhibiting pancreatic lipase activities, so it can be the diet therapy for obese patients.
* 5. Besides, Epsilon-Polylysine also can be used in cosmetics, disinfectant or cleaner for food machinery or hutch, etc.
