Epsilon-polylysine Usage
At present, ε-polylysine has been widely used in various fields such as food, medicine, and cosmetics.
Food field: It can be used for antisepsis preservation of milk, beverages, rice, cakes, pastry, sauces, meat products, canned food, etc. When polylysine is used as a bacteriostatic agent in foods, it is usually used in combination with other substances to achieve synergistic and economical purposes, such as alcohol, organic acids, glycerides, and the like.
In the field of medicine: ε-polylysine is rich in cations, has strong electrostatic interaction with substances with anions and has good penetrating power to biofilms. Based on this property, polylysine can be used for certain drugs. The carrier is therefore widely used in medical and pharmaceutical applications. The polymerization of ε-polylysine and methotrexate (a drug for treating leukemia and tumor) can improve the efficacy of the drug.
Cosmetics: Cosmetics are highly susceptible to microbial contamination and cause spoilage during storage and use. ε-PL can effectively inhibit harmful bacteria in cosmetics and is a natural, efficient and safe preservative in cosmetics.
