Poly-L-lysine (ε-poly-L-lysine, EPL) is a small natural homopolymer of the essential amino acid L-lysine that is produced by bacterial fermentation. ε-Poly-L-lysine is used as a natural preservative in food products.
Function: ε-Polylysine belongs to the group of cationic polymers. In water, ε-polylysine contains a positively charged hydrophilic amino group. According to research, ε-polylysine is adsorbed electrostatically to the cell surface of the bacteria, followed by a stripping of the outer membrane. This eventually leads to the abnormal distribution of the cytoplasm causing damage to the bacterial cell.
Polylysine has a light yellow appearance and is slightly bitter in taste whether in powder or liquid form. It is soluble in water, slightly soluble in ethanol, insoluble in organic solvent such as ethyl acetate, ether, ect.. Its activity is not affected by PH, and stable when heated (120°C for 20min). Therefore, it can be sterilized along with the raw material. It is a food preservative which is highly efficient, safe, and has no side-effects. Quality standard; FAO/WHO,1992
Application: ε-Polylysine was generally recognized as a safe food preservative by FDA in October,2003. It is widely used in food preservation. In food application, it is usually applied with alcohol, organic acids, or glyceride, etc.. It can be used in cooked rice, cakes, snacks, noodles, drinks, brewing, meat products, canned food, etc.
You may confect the 5-10%ε-Polylysine solution with cold boiled water or distilled water, then put it into the food and mix fully. If it is used together with other food preservatives, can attain better effect.
