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.
