Introduction of the preservative polylysine / fermented polyamino acids that contribute to food poisoning prevention.
We provide easy-to-understand materials explaining the natural preservative polylysine, which prevents food poisoning. ε-Polylysine (hereafter referred to as polylysine) is an amino acid-derived preservative widely used as a food preservative. 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 do not appear to be spoiled can rapidly proliferate microorganisms if the growth environment is suitable, so caution is necessary. Even if something looks clean, contamination by bacteria can progress, posing a risk of food poisoning. By ensuring hygiene management during the manufacturing process, proper storage at appropriate temperatures, and the appropriate use of the preservative polylysine, food safety can be more effectively protected. 【Features】 ■ A safe material produced through fermentation by natural microorganisms (not genetically modified organisms) ■ Provides a good image as a natural fermented product ■ Listed in the existing additive registry as a food preservative ■ A safe domestic product *Please feel free to contact us.
