High Qurity ε- Polylysine Hydrochloride Supplier


ε-Polylysine hydrochloride is a biological preservative derived from Streptomyces bacteria through adsorption, elution, and purification. It is a natural, safe, and non-toxic antimicrobial substance that shows significant inhibitory effects on various microorganisms, including Gram-positive bacteria, Gram-negative bacteria, and yeasts. Additionally, it possesses good water solubility and thermal stability, which allows it to maintain stable antibacterial effects during food processing and storage. Consequently, ε-polylysine hydrochloride has broad applications in food preservation, primarily due to its excellent antibacterial and preservative properties.

In rice, adding 0.1g/kg of ε-polylysine hydrochloride can extend the shelf life from 1 day to 5 days. When combined with citric acid, acetic acid, and other compounds, the shelf life can be further extended to over a week. For rice products like rice cakes, soaking them in a 0.5-1g/kg ε-polylysine hydrochloride alcohol solution for 10 minutes can effectively inhibit microbial growth and extend the shelf life.

In soda beverages, adding 50mg/kg-70mg/kg of ε-polylysine hydrochloride can meet the 12-month shelf life requirement. When used in combination with preservatives like parabens, the amount of ε-polylysine hydrochloride needed can be reduced, improving taste and lowering preservation costs.

Adding 30mg/kg-50mg/kg of ε-polylysine hydrochloride can inhibit microbial growth, and when combined with heat sterilization processes, it can meet the shelf life requirements of such products.

ε-Polylysine hydrochloride is also suitable for preserving other foods. By inhibiting the growth and reproduction of microorganisms, it can extend the shelf life and maintain the freshness and taste of these foods.

For meat products, ε-polylysine hydrochloride is an ideal preservative. It can effectively inhibit the growth of spoilage bacteria and pathogens in meat, thereby extending the shelf life of meat products and enhancing their safety.
