Development and production of high-purity γ-polyglutamic acid technology

Nippon Koji Co., Ltd. uses a liquid culture technology-based process to complete the mass production of an amino acid polymer, γ-polyglutamic acid (γ-PGA). This process is innovative in the world and γ-PGA can be used as a cosmetic raw material. This achievement has been registered in the INCI (International Cosmetic Ingredient Glossary) edited by the American Cosmetics Industry Association. Since γ-PGA can increase the absorbent capacity of human skin at the mouth, it can be sold to cosmetic manufacturers as a component of skin care products.
City Maruko uses the superior characteristics of γ-PGA to engage in the development of mass production techniques for γ-PGA. These include transformation to a liquid culture process, ie, passage. The ?-amino acid and the γ-carboxyl group of glutamic acid are peptide-coupled to generate a large amount of high-purity γ-PGA, and microorganisms are used in the process. Unlike many other companies that produce gamma-PGA, the goal of the City Pill Corporation's development plan is to use the cosmetic component as an end-use.
Compared with other components widely used in skin care products such as sodium hyaluronale and water-soluble collagen, it can be found that when γ-PGA with high moisture absorption energy is applied to the skin, Increases the production of pyrrolidone carboxylic acid, which is a natural wetting factor and a major component of lactic acid.
Since γ-PGA has a wide range of valuable applications, it can be used not only as a raw material for cosmetics, but also as a component of paints, as well as for the purification of water, and as a raw material for biodegradable plastics.
