Polyglutamic acid (γ-PGA), also known as natto gum and polyglutamic acid, is a water-soluble, biodegradable, non-toxic, biopolymer prepared by microbial fermentation. It has a white powder appearance and is a sticky substance. It was first discovered in "Natto". After fermentation, natto contains more vitamins (B2, B6, B12, E, K2) and more digestible protein than soybean itself. In addition, natto also contains a variety of digestive enzymes and special health benefits. Polysaccharides (Levan), thrombolytic enzymes (Nattokinase), and γ-polyglutamic acid (γ-PGA), etc., have excellent effects on promoting health and are widely used in the cosmetics and pharmaceutical fields.
