Polyglutamic Acid Powder for Dietary Supplement Industry

     Polyglutamic Acid Powder for Dietary Supplement Industry Overview Polyglutamic acid, commonly abbreviated as γ-PGA, is a naturally occurring biopolymer composed of repeating glutamic acid units linked through gamma-amide bonds. It is produced primarily through microbial fermentation, most commonly by strains of Bacillus subtilis. The resulting material is a water-soluble polymer widely used as a functional ingredient in food systems, nutritional products, and cosmetic formulations. Commercial polyglutamic acid ingredients are typically supplied as a white to off-white powder with defined molecular weight ranges. Unlike low-molecular-weight amino acids, γ-PGA is a high-molecular-weight polymer whose functional characteristics depend largely on its molecular size and polymer chain length. In industrial ingredient markets, polyglutamic acid products are standardized by molecular weight distribution rather than a single active compound percentage. Typical commercial materials range…
