Preservative Polylysine / Natural microbial fermented amino acids that contribute to food poisoning prevention.
Polylysine is a polyamino acid used as a food preservative. It contributes to the prevention of foodborne illnesses, which have become a problem in recent years.
ε-Polylysine (hereinafter referred to as Polylysine) is a homopolymer consisting of 25 to 35 units formed by the amine group at the ε-position and the carboxyl group at the α-position of the amino acid L-lysine, linked by amide bonds. It has over 30 years of manufacturing experience and is widely used as a food preservative derived from amino acids. By adding Polylysine, the growth of microorganisms that cause food poisoning can be prevented. Every year, food poisoning caused by microorganisms is a significant issue and is frequently reported in the news. Even foods that appear to be fresh can experience rapid microbial growth if the conditions are right, so caution is necessary. Even if the appearance is good, contamination by bacteria can progress, posing a risk of food poisoning. In addition to hygiene management during the manufacturing process and proper storage at appropriate temperatures, the effective use of the preservative Polylysine can help ensure food safety more effectively. 【Features】 ■ A safe material produced through fermentation by natural microorganisms (not genetically modified organisms) ■ Provides a positive image as a natural fermentation product ■ Listed in the existing additive registry as a food preservative ■ A safe domestic product
