Epsilon Polylysine
General product information
description:?-polylysine is a naturally produced, cationic homopolymer of 25-30 L-lysine(due to Streptomyces albulus fermentation.), which was connected by ?-amido bond compounded by a e-amido of l-lysine and a e-carboxyl of another l-lysine.
?-polylysine can greatly inhibit the growth of bacteria, yeasts and moulds bacteria, especially to the Gram+ bacteria which can't easily inhibit by others. As a good preservative, ?-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. 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.
? - PL can stop small intestine fat absorption through inhibiting pancreatic lipase activities, so it can be the dietotherapy for obese *des, ? - PL also can be used in cosmetics, disinfectant or cleaner for food machinery or hutch, etc.
