ε-Polylysine is a homopolymer of L-lysine, one of the essential amino acids. It is linked by peptide bond formed with α-carboxyl of L-lysine and ε-azyl from other L-lysine.
ε-Polylysine ?molecular weight is between 3200~4500 g/mol (degree of polymerization = 25~35).ε-Polylysine is hygroscopic, light yellow power. It is soluble in water, slightly soluble in ethanol, insoluble in organic solvent such as ethyl acetate, ether, ect.. The molecular of ε-Polylysine is a straight chain polymer of lysine. It can decompose to lysine in human body, and can be completely digested to absorption by the human body. ε-Polylysine can inhibit the growth of G+ and G- bacteria , yeast, mould, virus and ect, especially inhibit the G- bacteria which can’t be easily inhibited by other preservatives, such as E.coli, Salmonella, and also can inhibit the thermophilics, such as B,stearothermophilus. Its activity is not affected by PH, and stable when heated (120℃ for 20min). Therefore, it can be sterilized along with the raw material.
