Gamma Polyglutamic Acid
Gamma Poly-glutamic acid (γ-PGA) is a natural occurring, multi-functional, and biodegradable biopolymer. It is produced through fermentation by Bacillus subtilis using glutamic acid. PGA is consists of glutamic acid monomers crosslinked between α-amino and γ-carboxyl groups. It is water-soluble, edible and non-toxictowards human, and is environment friendly. It has broad applications in the fields of medicine, food, cosmetics, and water treatment. Key Technical Parameters:

Applications: γ-PGA widely used in the Pharmaceutical,food industry, cosmetics,water treatment, hygienic products, agriculture and other Hi-tech industries. Gamma Polyglutamic Acid,first recognized in Japanese food ‘Natto’,it is a natural multifunctional Biopolymer,produced with Bacillus Subtilis by fermentation. Gamma Polyglutamic Acid(Gamma PGA) is a water soluble homopolymer,it consists of D-Glutamic Acid and L-Glutamic Aid monomers which are connected by amide linkages between α-amino and γ-Carboxyl groups. Large number of Carboxyl Groups along the molecule chain of Gamma PGA can form hydrogen bonding in a molecule or between different molecules.Thus it has high water absorbability and moisture retaining capability.Thanks to its unique properties, Gamma PGA can be used as thickener,filmogen,humcctant,retarder,cosolvent,binder and anti-freezer,therefore,the application prospect of Gamma PGA is promising.
