E-Polylysine 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.
E-Polylysine is a high-efficiency antimicrobial agent or preservative. It is produced from a fermentation process using Streptomyces albulus under aerobic conditions. It has obvious inhibition to gram-positive bacteria and Gram-negative bacteria, yeast, mould, virus. In addition, it also has excellent safety, therefore it is widely used as an antistaling agent.
ε-Polylysine is pale yellow powder, strong hygroscopicity, slightly bitter; Easily soluble in water. Not in organic solvents such as alcohol,ether.

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.
Preserve your products safety with naturally fermented ε-Polylysine.
Antimicrobial agent Polylysine is an efficient preservative. It is fermented using Stretomyces albulus under microbic conditions. It inhibits gram-positive bacteria and electronegative bacteria, yeasts, moulds and viruses. It also has a great safety record and is widely used as a preservative in peanut butter, fried noodles,Japanese box lunch, cakes, pastry, snack foods , butter , salads, sauces, beverages, wine and meat products.
