Description

Sodium Ascorbate is the sodium salt of ascorbic acid (Vitamin C), a vital water-soluble nutrient and antioxidant. This compound is prized for its superior stability and solubility in water compared to ascorbic acid, making it an essential ingredient for fortification and preservation. It serves as a critical functional additive for manufacturers in the food, pharmaceutical, nutraceutical, and cosmetic industries, where it acts as an antioxidant, acidity regulator, and nutrient source.

Application

• Food & Beverage Industry: Used as an antioxidant (E301) to prevent oxidation and browning in meats, canned fruits, and beverages; as a nutrient enhancer for Vitamin C fortification in juices, dairy products, and baked goods.
• Pharmaceutical & Nutraceutical Formulations: A key active ingredient and excipient in vitamin C supplements, effervescent tablets, syrups, and injectable solutions due to its high bioavailability and buffered nature.
• Cosmetics & Personal Care: Employed in anti-aging serums, creams, and lotions for its antioxidant properties, helping to protect the skin from free radical damage and support collagen synthesis.
• Animal Feed & Nutrition: Incorporated into premixes and feed for livestock, poultry, and aquaculture to boost immune function, reduce stress, and improve overall health.
• Technical & Industrial Uses: Functions as a reducing agent in various chemical processes, including photographic development and water treatment applications.
