Epsilon Polylysine Epsilon Polylysine Introduction Epsilon Polylysine is a naturally produced, cationic homopolymer of 25-30 L-lysine(due to Streptomyces albulus fermentation.), which was connected by ε-amido bond compounded by a e-amido of l-lysine and a e-carboxyl of another l-lysine.

Epsilon Polylysine

Epsilon Polylysine Introduction

Epsilon Polylysine is a naturally produced, cationic homopolymer of 25-30 L-lysine(due to Streptomyces albulus fermentation.), which was connected by ε-amido bond compounded by a e-amido of l-lysine and a e-carboxyl of another l-lysine.

Characteristics

◆Various functions: Polylysine molecules are cationic, surface active agents in water due to their positively charged amino groups. This property imports many benefits when used as an ingredient in cosmetics.

◆Very safe.

◆Easy to use: readily soluble in water, highly heat-stable and useable over a wide pH range (5-8).

As can be seen, ε-PL has wide range of antimicrobial spectrum with minimum inhibitory concentration of bacteria less than 100μg/ml, and to Fungi, the MIC is higher.

Ε-PL can effectively inhibit the growth of undesirable microorganisms in foods, such as bakery food( bread , cake etc.), beverage( soybean milk, fruit beverage) and meat products.
