Polylysine is widely used as a food additive and, thanks to its GRAS certification (Note) from the U.S. FDA, is recognized as a global standard food preservative. As of August 2, 2022, the only polylysine with FDA GRAS certification is the polylysine produced by JNC Corporation. Polylysine is a naturally occurring amino acid-derived substance produced by microbial fermentation, similar to miso, soy sauce, yogurt, and other products. Polylysine ionically adsorbs to microorganisms, inhibiting their growth. Due to its broad antibacterial properties and excellent flavor-preserving properties, it is primarily used to extend the shelf life of foods, and is used in a wide range of food products, including ekiben (boxed lunches), soraben (boxed lunches sold at supermarkets), and prepared meals. Note: GRAS (Generally Recognized as Safe) is a safety standard certification given to food additives by the U.S. Food and Drug Administration (FDA). To be generally recognized as safe through scientific procedures, quantitative and qualitative scientific evidence equivalent to that required for approval of a substance as a food additive is required. *For more information, please download the PDF or feel free to contact us.

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. Polylysine has excellent antibacterial properties on its own, but when added to food, its effectiveness may not be fully realized due to the influence of food components. Therefore, when used in food, it can be combined with other substances to mitigate the effects of food components or enhance its antibacterial effects. In particular, combining Polylysine with substances that suppress microorganisms through different mechanisms, such as ethanol, organic acids, glycine, and glycerol fatty acid esters, can yield excellent synergistic effects.

Bread making involves many processes, but if the dough can be frozen after shaping, it allows for the omission of steps prior to secondary fermentation, significantly reducing the time required for thawing, fermentation, and baking. However, freezing the dough can lead to the destruction of yeast cells and damage to the dough structure due to ice crystal formation, resulting in a decrease in volume. This volume reduction is one of the freezing injuries of bread dough. Polylysine is a safe fermented food that has been used as a preservative for many years and has the function of suppressing freezing injuries in bread. Bread with added Polylysine bakes up fluffier compared to bread without it. 【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

It has over 30 years of manufacturing history and is widely used as an amino acid-derived food preservative. The shelf life of typical pet food is 2 to 3 years, but wet-type pet foods, such as treats, often have a shorter shelf life of only about 1 year. Methods for extending shelf life include canning, pouch processing, and converting to dry food, but these are not suitable for flavorful pet foods like wet types. Additionally, some pet owners do not refrigerate after opening. This can lead to mold growth or spoilage during storage, potentially harming the pet's health. Polylysine is a food preservative used in bento, bread, and side dishes, and it is gaining attention as a food preservative that can help prevent spoilage in pet food. 【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 domestically produced product
