ε-Polylysine Hydrochloride Manufacturer,High Safety

ε-Polylysine hydrochloride is regarded as a guardian of food safety, primarily due to its broad-spectrum antibacterial properties, high safety, good thermal stability, and strong water solubility.ε-Polylysine hydrochloride has excellent antibacterial effects against various microorganisms, including Gram-positive bacteria, Gram-negative bacteria, yeasts, and molds. Additionally, it can inhibit some heat-resistant spore-forming bacteria and viruses. It shows significant inhibitory effects on bacteria that cause food poisoning and spoilage, such as Escherichia coli, Salmonella, Aerobacter, Pseudomonas putida, Pseudomonas aeruginosa, and even some viruses like bacteriophages.

Reportedly, ε-polylysine hydrochloride was approved by the U.S. Food and Drug Administration (FDA) in 2003 and by the National Health and Family Planning Commission of China as a new food additive in 2014, further proving its safety. When ingested by the human body, ε-polylysine hydrochloride can be degraded into L-lysine, which is an essential amino acid for humans, further used for protein synthesis or continued metabolism, with no toxicity.

ε-Polylysine hydrochloride exhibits good stability under high-temperature conditions. For example, its aqueous solution maintains the minimum inhibitory concentration against Escherichia coli after being treated at 80°C for 60 minutes, 100°C for 30 minutes, and 120°C for 20 minutes, indicating that it does not decompose or lose activity under high temperatures. This allows it to undergo sterilization with raw materials and adapt to various food processing processes. Additionally, the good water solubility of ε-polylysine hydrochloride makes it easy to add to food, facilitating food production operations.

ε-Polylysine hydrochloride is widely used in various foods such as cakes, pastries, fast food, butter, salad dressings, beverages, alcoholic drinks, meat products, and canned foods. Its usage varies depending on the type and form of food but generally serves as an excellent preservative. Besides the food industry, it is also used in the daily chemical and pharmaceutical industries. For example, it can be used as a preservative in daily chemical products and as a drug carrier in the pharmaceutical field or in combination with other drugs to enhance efficacy.

With its broad-spectrum antibacterial properties, high safety, good thermal stability, and strong water solubility, ε-polylysine hydrochloride plays an important role in ensuring food safety. Therefore, it is aptly named the guardian of food safety.
