Effect of Polylysine on the Inactivation of Microorganisms
Natural amino acid 'Polylysine' as an additive in food preservatives, hygiene materials, and daily necessities. Introducing the inactivation effect of polylisine against microorganisms.
ε-Polylysine (hereinafter referred to as Polylysine) is a substance formally known as ε-Poly-L-lysine. It is a homopolymer consisting of 25 to 35 units linked by amide bonds, formed from the ε-amino group and the α-carboxyl group of the essential amino acid L-lysine. Since 1989, it has over 30 years of manufacturing history and is widely used as a food preservative amino acid. It demonstrates inactivation effects against various microorganisms. Polylysine not only suppresses the growth of microorganisms but also has the effect of inactivating them. It similarly shows inactivation effects against enterohemorrhagic Escherichia coli O157:H7 and O111:H8. From the perspective of suppressing food spoilage, it is important to keep the initial bacterial count low, and Polylysine, which inactivates microorganisms and reduces the initial bacterial count, has excellent properties as a preservative. *For more details, please download the PDF or feel free to contact us.
