  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...
