GAMMA-POLY-GLUTAMIC ACID
1. γ-PGA:
Gamma-poly-glutamic acid (γ-PGA) is an all natural, multi-functional, biodegradable biopolymer produced from L-glutamic acid through a fermentation process with a Bacillus subtilis sp..
γ-PGA has a molecular weight ranging from about 10,000 up to 2 millions, can be produced to meet the requirement of different applications.
γ-PGA is a food grade product, which can be used as a diet fiber in health food supplement, a thickener or stabilizer in food product, an excellent moisturizer in skin care preparations.
γ-PGA can be made into hydrogel, which has a super water-binding ability, and can absorb water up to 3500 times of its weight, is excellent for agricultural and environmental applications.
γ-PGA adds in calcium adsorption, and is an excellent health care supplement for controlling loss of calcium from bone for seniors, or facilitating the adsorption of calcium for juniors.
γ-PGA can be made into different ionic form, pH, and characteristic poly-anionic surface, which is an excellent medium for tissue culture and many other food, cosmetic, biomedical and industrial applications.
