Supply food-grade ε-polylysine hydrochloride


Food-grade ε-polylysine hydrochloride possesses a range of remarkable characteristics that make it widely used in the food industry.

ε-polylysine hydrochloride exhibits broad-spectrum antibacterial capabilities, effectively inhibiting the growth of a variety of microorganisms, including Gram-positive and Gram-negative bacteria, yeasts, molds, and even viruses. This strong antimicrobial function helps to extend the shelf life of food products, reducing the risk of spoilage and deterioration.

ε-polylysine hydrochloride also has excellent thermal stability. It maintains its antibacterial activity without decomposing even when exposed to high temperatures, such as 121°C for 30 minutes. This allows it to be heat-treated along with raw materials during food processing without losing its functionality.

Additionally, ε-polylysine hydrochloride is highly soluble in water, with a solubility of at least 500g/L, making it easy to distribute evenly in food and exert its antimicrobial effects. It exhibits strong antibacterial capabilities across a pH range of 2 to 9, compensating for the reduced activity of other preservatives under neutral and alkaline conditions.

The safety of ε-polylysine hydrochloride is extremely high. Acute toxicology tests show that its LD50 value is 5g/kg, comparable to table salt. Importantly, after ingestion, it can be digested, absorbed, and broken down into lysine, an essential amino acid for the human body, without side effects.

Furthermore, ε-polylysine hydrochloride exhibits excellent synergistic effects. It can be used alone or in combination with other food additives (such as vinegar, ethanol, and glycine), significantly enhancing its bactericidal effects.

ε-polylysine hydrochloride also has health-promoting functions. Studies have shown that it can effectively inhibit enzyme activity and fat absorption, helping to reduce the occurrence of obesity.

With its broad-spectrum antibacterial, thermally stable, highly soluble, safe, and synergistically enhancing properties, food-grade ε-polylysine hydrochloride plays a crucial role in the food industry, providing effective solutions for ensuring food safety and extending shelf life.
