As a natural preservative, ε-polylysine has unique application conditions. It is similar to the benchmark nisin of natural preservatives. It is a polypeptide preservative, and ε-polylysine is more bacteriostatic than nisin. Wider. Most natural preservatives have a very good antibacterial effect on Gram-positive bacteria, but have no obvious effect on Gram-negative bacteria such as Escherichia coli. The emergence of ε-polylysine breaks this "potential". "Rules", it also has obvious antibacterial and killing effects on Gram-negative bacteria such as Escherichia coli and Arthrobacter products, and has outstanding broad-spectrum antibacterial effects.

A peptide which is a homopolymer of lysine.
ε-Polylysine is a light yellow powder with strong hygroscopicity and slightly bitter taste. It is a linear polymer of lysine. It is produced by streptomyces fermentation and has a broad-spectrum antibacterial effect. ε-polylysine is polymerized by 25-30 lysine groups, which is relatively stable to pH and heat. Its antibacterial effect is related to the degree of polymerization and the environment. The molecular weight of polylysine is between 3600-4300 which has the best antibacterial activity.
In 1977, Japanese scholars S. Shima and H. Sakai, in the process of screening Dragendo~Positive (DP) substances from microorganisms, discovered that a strain of actinomycete No.346 can produce a large amount of stable DP substances. The analysis and structural analysis of the hydrolysate confirmed that the DP substance is a homopolymer of 25-30 lysine residues. A homologous amino acid polymer formed by NH2 condensation, so it is called ε-Poly-L-lysine (ε-Poly-L-lysine for short ε-PL).
