The safety of ε-polylysine hydrochloride has been widely recognized. Its acute toxicity test (LD50) is 5g/kg, which is comparable to table salt. After ingestion, it degrades into lysine, a nutrient that can be absorbed and utilized by the body without any toxic or side effects. Additionally, it has been approved as a legal food additive by several countries and is widely used in the food industry.
Application of ε-Polylysine Hydrochloride in Food
·As a Preservative: ε-Polylysine hydrochloride has broad-spectrum antibacterial properties and can inhibit Gram-positive bacteria, Gram-negative bacteria, fungi, and some heat-resistant spore-forming bacteria. Therefore, it is widely used as a food preservative. It can be used in various foods, including fruits, vegetables, beans, edible fungi, rice and rice products, wheat flour and its products, grains, meat and meat products, seasonings, beverages, etc., to extend the shelf life of food.
·Improving Shelf Life: ε-Polylysine hydrochloride effectively inhibits the growth of microorganisms, thereby increasing the shelf life of food. It can be applied to foods like instant rice and fast food to maintain freshness and texture.
·Combined Use with Other Substances: ε-Polylysine hydrochloride can be combined with other substances (such as alcohol, organic acids, glycerides, etc.) to achieve better preservation and fresh-keeping effects. For instance, mixing it with glycine can extend the shelf life of milk.
