1> ε-polylysine can greatly inhibit the growth of bacteria, yeasts and moulds bacteria, especially to the Gram- bacteria which can not easily inhibit by others.
2> As a good preservative, ε-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> ε-polylysine can stop small intestine fat absorption through inhibiting pancreatic lipase activities, so it can be the diet therapy for obese patients.
5> Besides, ε-polylysine also can be used in cosmetics, disinfectant or cleaner for food machinery or hutch, etc.
