Description

Sodium Erythorbate is the sodium salt of erythorbic acid, a stereoisomer of ascorbic acid (Vitamin C). It serves as a highly effective antioxidant and preservative, primarily used to prevent oxidation and maintain the color, flavor, and freshness of various products. This compound is essential for manufacturers in the food and beverage, pharmaceutical, and cosmetic industries who require a safe, water-soluble, and potent antioxidant. Sodium Erythorbate CAS NO 7378-23-6 is a key ingredient for quality assurance and shelf-life extension.

Application

• Food & Beverage Industry: As a primary antioxidant in processed meats (bacon, ham, sausages) to fix color and inhibit nitrosamine formation, and in canned fruits, vegetables, and beverages to prevent browning and flavor loss.
• Pharmaceuticals: Used as an antioxidant in injectable solutions, topical formulations, and tablets to stabilize active pharmaceutical ingredients (APIs) susceptible to oxidative degradation.
• Cosmetics & Personal Care: Incorporated into creams, lotions, and serums to protect formulations from oxidative rancidity and enhance product stability.
• Industrial Applications: Acts as an oxygen scavenger in boiler water treatment and as a reducing agent in various chemical synthesis processes.
• Wine & Brewing: Utilized as an antioxidant to prevent oxidation and preserve flavor profiles during production and storage.

Quality Control

Our Sodium Erythorbate is manufactured under strict quality management systems. We supply grades compliant with major international standards, including FCC (Food Chemicals Codex) and Food Grade specifications, ensuring safety and efficacy for food and pharmaceutical applications. Every batch undergoes rigorous analytical testing. Certificates of Analysis (COA) documenting purity, identity, and safety parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and easily oxidized; therefore, containers must be kept tightly sealed after opening to minimize exposure to air and moisture. For long-term storage, consider using an inert atmosphere.
