1. ε-polylysine Introduction

ε-polylysine is a naturally produced, cationic homopolymer of 25-35 L-lysine(due to Streptomyces 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. 

2. ε-polylysine Effect

1> ε-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, 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.

3. Hazard Identification
ε-Polylysine was found to be non-toxic at high levels in acute animal studies and was not mutagenic in bacterial reversion assays. ε-Polylysine is “Generally Recognized As Safe” (GRAS. GRN000315) by the FDA.
