CAS 25513-46-6 Polyglutamic Acid γ-PGA Powder
What is Polyglutamic Acid?
Polyglutamic acid (γ-PGA) is a natural biopolymer produced by microbial fermentation. It is water-soluble, biodegradable, and non-toxic. It was first isolated from natto, a traditional Japanese fermented food, hence its nickname, natto gum. As a fermented soybean product, natto boasts significantly higher nutritional value than the raw soybeans. It is rich in B vitamins (B2, B6, B12), vitamins E and K2, and a more easily absorbed form of protein. Natto also contains a variety of functional ingredients, including digestive enzymes, fructans, the thrombolytic enzyme nattokinase, and γ-polyglutamic acid. The synergistic effects of these substances have made it a popular health food in recent years. γ-PGA, as the specific sticky component of natto, together with other active substances in natto, forms the basis for its health-promoting properties.
What are the benefits？
Skincare Benefits
1. Promotes Nutrient Absorption: Significantly improves the skin's mineral absorption and utilization efficiency.
2. Multi-Moisturizing and Repairing: Enhances skin elasticity, improves skin smoothness, locks in moisture for long-lasting hydration, and reduces wrinkle formation.
3. Comprehensive Beauty Benefits: Inhibits melanin production for a whitening effect, optimizes nutrient absorption, and maintains a healthy skin pH balance.
Agricultural Applications
1. Soil Improvement: Improves soil aggregate structure and enhances water and fertilizer retention, delivering a slow-release fertilizer four times more effective than traditional fertilizers.
2. Increases Yield and Improves Quality: Increases fertilizer utilization by 10%-30%, boosting crop yields by 8%-31% (particularly significant for staple crops like rice), and improving agricultural product quality.
3. Ecological Protection: Reduces fertilizer use by over 20% in poor soils, reduces agricultural pollution through microbial degradation, and improves the rural ecological environment.
4. Sustainable Development Significance: As a new biosynergist, it has important practical value in promoting ecological agriculture and achieving sustainable agricultural development, providing technical support for the rural revitalization strategy.
