physical properties

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 for lysine within the human body, and can be completely digested absorption by the human body,not only doesnt have any poisonous side-effect, but also can be regard as the source of one kind of lyisine.

 

ε-Polylysine can inhibit the growth of Gram(+) and Gram(-) bacteria , yeast, mould, virus, ect., especially inhibit the Gram(-) bacteria which cant easily inhibit by other preservatives,such as E.coli, Salmonella, and also can inhibit the thermophilics, such as B,stearothermophilus.
