Epsilon Poly l lysineIntroduction
CAS No.: 28211-04-3 Epsilon polylysine is a naturally produced, cationic homopolymer of 25-30 L-lysine(due to Streptomyces albulus fermentation. ), which was connected by epsilon amido bond compounded by a e-amido of l-lysine and a e-carboxyl of another l-lysine. ITEM STANDARD Description Off white powder Polylysine Purity More than 99% Loss on drying Less than 10% Residue on ignition Less than 1% Heavy metals Less than 20ppm Arsenic Less than 4ppm Epsilon polylysine Effect 1. E-polylysine can greatly inhibit the growth of bacteria, yeasts and moulds bacteria, especially to the Gram+ bacteria which can't easily inhibit by others. 2. As a good preservative, E-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. 3. 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. 4. E- PL can stop small intestine fat absorption through inhibiting pancreatic lipase activities, so it can be the diet therapy for obese patients. 5. Besides, E - PL also can be used in cosmetics, disinfectant or cleaner for food machinery or hutch, etc...
