[Introduction]

Epsilon-Polylysine is a polymer if L-Lysine, an essential amino acid required for human health. It is a natural polypeptide antimicrobial produced by bacterial fermentation from streptomyces strains. it has various functions such as preservative and surfactant.

[Usage]
E-Polylysine was generally recognized as safe as Food Preservative by FDA in October, 2003.
It is widely used as food preservation in rice, noodles, cakes, snacks, and ice creams, salad, canned foods and meat products.

[Characteristics]

1.High safety. Polylysine can be decomposed to lysine in the human body, and L-lysine is one of eight essential amino acids, and is the amino acid allowed strengthening in food allover the world. So polylysine is a nutritional antibacterial agent, and safer than other chemical preservatives.

2.Wide antibacterial spectrum---esp. to Gram+ and Gram- bacteria.The antibacterial spectrum of poly-L-lysine is broad, which has strong inhibitory effect to Candida, Phaffia rhodozyma, Pichia yeast, Sporobolomyces roseus; Gram-positive bacteria, Bacillus stearothermophilus, Bacillus coagulans, Bacillus subtilis; Gram-negative bacteria, Enterobacter, E. coli.

3.The optimal pH The antibacterial optimal pH of poly-L-lysine is 5-8, and possesses strong antibacterial activity in neutral and weak acid environment.

4.Thermal stability Polylysine has good thermal stability, which can withstand heat treatment process in general food processing, and sterilized together with the raw materials to prevent secondary pollution.
