Epsilon-Polylysine is a natural substance from microbial metabolism. It is widely used as food preservative. It is slightly bitter, hygroscopic, light yellow power. And it is soluble in water, slightly soluble in ethanol. The molecular of E-Polylysine is a straight chain polymer of L-lysine. Its activity is not affected by pH, and stable when heated (120C for 20 min). Epsilon-Polylysine can inhibit the growth of Gram(+) and Gram(-) bacteria such as E. Coli and Bacillus subtilis, yeast, lactic acid bacteria, Staphlacoccus aureus and so on.
