Description

Sodium Erythorbate is the sodium salt of erythorbic acid, a stereoisomer of ascorbic acid (Vitamin C). This highly effective antioxidant is crucial for preventing oxidation and color degradation in a wide range of processed products. It is an essential ingredient for manufacturers in the food, beverage, and pharmaceutical industries seeking to extend shelf life and maintain product quality. Sodium Erythorbate CAS NO 6381-77-7 offers superior water solubility compared to its acid form, making it ideal for various aqueous applications.

Application

• Food Preservation: Primary antioxidant in cured and processed meats (bacon, ham, sausages) to prevent rancidity and fix color.
• Beverage Industry: Used in soft drinks, beers, and wines to inhibit oxidation, preserve flavor, and prevent browning.
• Fruit & Vegetable Processing: Prevents enzymatic browning in canned, frozen, and dried products to maintain visual appeal.
• Seafood: Extends shelf life and prevents discoloration in frozen fish and shellfish.
• Bakery & Dairy: Improves dough stability and acts as an antioxidant in certain dairy-based products.
• Pharmaceuticals: Serves as an antioxidant in formulations to stabilize active ingredients susceptible to oxidation.
