ε- Polylysine Hydrochloride Powder Manufacturer

ε-Polylysine hydrochloride is a food additive obtained from the controlled fermentation broth of starch-amylase-producing Streptomyces through ion exchange resin adsorption, desorption, and purification. It is an amino acid with antibacterial properties, safe and eco-friendly, easy to blend with other products, and has been approved as a safe food preservative in countries such as the United States, Japan, South Korea, and China. Experiments in mice have confirmed that it does not produce toxic or side effects on organisms. ε-Polylysine hydrochloride powder is widely and effectively used in food preservation.

ε-Polylysine hydrochloride exhibits good inhibitory effects on the growth and reproduction of Gram-positive bacteria, Gram-negative bacteria, and fungi. It achieves antibacterial effects by electrostatically adsorbing onto cell membranes, altering membrane permeability, disrupting cell structure, and inhibiting cell metabolism.

ε-Polylysine hydrochloride has been used in post-harvest preservation studies of various fruits and vegetables such as apples, bamboo shoots, kiwifruits, carrots, and citrus fruits. It significantly reduces the decay rate and respiration intensity, delays browning, and maintains good quality of the produce.

In coconut juice beverages, the effect of using ε-polylysine hydrochloride alone is limited. However, when combined with other preservatives such as sodium benzoate and EDTA, the antibacterial effect is significantly enhanced. The recommended blending ratio is 0.08g/kg ε-polylysine hydrochloride, 0.3g/kg sodium benzoate, and 0.03g/kg EDTA, achieving antibacterial rates of 98% for bacteria and 96% for mold. The specific usage amount needs to be adjusted based on actual conditions. The recommended dosage in coconut juice beverages is 0.06-0.08g/kg. Combining it with other preservatives or preservation methods can significantly enhance its antibacterial activity through synergistic effects and reduce preservation costs.

As a natural, safe, and effective food preservative, ε-polylysine hydrochloride powder has broad application prospects in the field of food preservation. Its broad-spectrum antibacterial properties and good safety make it an ideal alternative to traditional chemical preservatives. In practical applications, the usage amount and blending ratio should be reasonably adjusted according to the type of food and preservation needs to achieve the best preservation effect.
