Product Introduction:
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, and the molecular weight of PGA is usually between 100~1000 kDa. 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.
First recognized in Japanese food Natto, gamma-polyglutamic acid (y-PGA) is a natural multifunctional biopolymer
produced with Bacillus Subtilis by fermentation. Gamma PGA is a water soluble homo-polyamide. It consists of D-and L-glutamic acid monomers which are connected by amide linkages between amino and y-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.
