ε-polylysine (ε-poly-L-lysine, ε-PL for short) is a homopolymer of L-lysine which is the essential amino acid for human body.
ε-polylysine can greatly inhibit the growth of Gram-positive bacteria, Gram-negative bacteria, yeasts, moulds, viruses etc. It has been widely used in food, daily chemical, pharmaceutical and other industries. ε-polylysine can be completely digested and absorbed by the body, and broken down into the essential lysine in human body without any side effects.

Function and Advantage:
1> ε-polylysine can greatly inhibit the growth of bacteria, yeasts and moulds bacteria, especially to the Gram+ bacteria which can’t easily inhibit by others.
2> As a good preservative, ε-PL 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> ε - PL can stop small intestine fat absorption through inhibiting pancreatic lipase activities, so it can be the diet therapy for obese patients.
5> Besides, ε - PL also can be used in cosmetics, disinfectant or cleaner for food machinery or hutch, etc..
