Polyglutamic Acid Newgreen Supply Food Grade Amino Acids PGA Polyglutamic Acid Powder
Product Description
Polyglutamic acid (poly-γ-glutamic acid, English poly-γ-glutamic acid, abbreviated PGA) is a water-soluble polyamino acid produced by microbial fermentation in nature, and its structure is a high polymer in which glutamic acid units form peptide bonds through α-amino and γ-carboxyl groups.
The molecular weight ranges from 100kDa to 10000kDa. Poly - γ-glutamic acid has excellent water solubility, strong adsorption and biodegradability, degradation product for pollution-free glutamic acid, is an excellent environmental protection polymer material, can be used as water retention agent, heavy metal ion adsorbent, flocculant, sustained release agent and drug carrier, etc. It has great value in cosmetics, environmental protection, food, medicine, agriculture, desert management and other industries.

Function
Moisturizing effect: Polyglutamic acid can effectively absorb and retain water, help improve the moisturizing properties of food, and extend the shelf life of food.
Thickener: As a natural thickening agent, polyglutamic acid can improve the texture and mouthfeel of foods, making them thicker and smoother.
Improve flavor: Polyglutamic acid can enhance the flavor of food and enhance the overall taste experience.
Nutritional Enhancement: Due to its amino acid properties, polyglutamic acid may help improve the nutritional value of foods, especially in foods with low protein content.
Antioxidant properties: Polyglutamic acid may have a certain antioxidant effect, helping to delay the oxidation process of food and maintain the freshness of food.
Promote gut health: As a soluble fiber, polyglutamic acid may help promote intestinal health and improve digestive function.
Application
Thickener: Polyglutamic acid is widely used as a natural thickening agent in soups, sauces, dairy products and beverages to improve their texture and mouthfeel.
Moisturizer: In baked goods and meat products, polyglutamic acid can help retain moisture, extend the shelf life of food, and prevent drying out.
Flavor enhancers: Polyglutamic acid can enhance the flavor of food and improve the overall taste experience. It is often used in condiments and ready-to-eat foods.
