ε-Polylysine

YOTABIO ε-Polylysine (ε-poly-L-lysine) is a fermentation-derived antimicrobial ingredient produced using Streptomyces albulus. Composed of linked L-lysine units, it helps food manufacturers manage microbial spoilage and develop effective shelf-life solutions. Yota Bio-Engineering Co., Ltd With activity against susceptible Gram-positive and Gram-negative bacteria, as well as selected yeasts and moulds, ε-Polylysine offers a broad-spectrum option for preservation-system development. Its positively charged structure interacts with microbial cell membranes, disrupting their integrity and inhibiting growth. Yota Bio-Engineering Co., Ltd Application areas include cooked rice and noodles, ready-to-eat meals, meat and poultry, seafood, sauces, bakery products and selected beverages, where authorised. It can be evaluated individually or alongside other preservation ingredients and processing controls to meet product-specific shelf-life requirements. Yota Bio-Engineering Co., Ltd Supplied as a water-soluble powder, YOTABIO ε-Polylysine supports convenient incorporation into aqueous formulations. Its thermal stability makes it a useful candidate for heat-processed foods, with performance confirmed under the customer’s actual production conditions. Compatibility should be assessed in complex formulations, particularly those containing proteins or negatively charged hydrocolloids. Yota Bio-Engineering Co., Ltd Final dosage should be established through application trials, considering the selected grade, target microorganisms, formulation, pH, processing and storage conditions. Permitted applications, use levels and labelling must be confirmed for the destination market.
