Description

Sodium Erythorbate Monohydrate is the sodium salt of erythorbic acid, a stereoisomer of ascorbic acid (Vitamin C). This high-purity antioxidant is essential for preserving color, flavor, and shelf life in a wide range of perishable goods. It is a critical ingredient for manufacturers in the food and beverage, pharmaceutical, and cosmetic industries seeking effective, food-grade solutions to prevent oxidation and spoilage. Its superior stability in aqueous systems makes it a preferred choice for water-based applications.

Application

• Food & Beverage Preservation: Primary antioxidant in cured and processed meats (bacon, ham, sausages) to prevent nitrosamine formation and maintain red color.
• Beverage Stabilization: Used in soft drinks, beers, and wines to inhibit oxidation, prevent browning, and protect flavor profiles.
• Fruit & Vegetable Processing: Prevents enzymatic browning in canned, frozen, and dried fruits and vegetables.
• Seafood & Poultry: Extends shelf life and maintains the fresh appearance of frozen and fresh products.
• Pharmaceutical Excipient: Acts as an antioxidant in certain pharmaceutical formulations to enhance stability.
• Cosmetic Formulations: Used in skincare products as an antioxidant to protect formulations from oxidative degradation.
