Potassium Ascorbate is the potassium salt of ascorbic acid (Vitamin C), widely used as a food antioxidant, preservative, and nutritional fortifier. It helps prevent oxidation, extend shelf life, and maintain the color, flavor, and nutritional value of food products.
Compared with other vitamin C derivatives, Potassium Ascorbate offers a milder taste and better stability in certain formulations, making it suitable for beverages, functional foods, and dietary supplements.
