Polyglutamic acid (γ-PGA), also known as natto gum and polyglutamic acid, is a water-soluble, biodegradable, non-toxic, sticky substance that is used in “natto” —First discovered in fermented beans. Polyglutamic acid (γ-PGA) is a macromolecular amino acid polymer produced by biological fermentation process and is available in two forms: powder and liquid.
Polyglutamic acid (γ-PGA) is a special anionic natural polymer, a homopolyamide composed of linear amide bonds of glutamic acid between α-amino groups and γ-carboxyl groups.
Polyglutamic acid (γ-PGA) is an amino acid polymer synthesized by microbial fermentation. It has excellent biocompatibility and biodegradability. It can be used as a biomedical material, sewage treatment material, and can also be used as a food thickener. , food antifreeze and preservation, cosmetics moisturizer and agriculture and other fields.
