Description

Erythorbic Acid is a stereoisomer of ascorbic acid (Vitamin C) widely valued as a highly effective food-grade antioxidant and preservative. Its primary commercial value lies in preventing oxidation, thereby maintaining color, flavor, and shelf life in a variety of perishable goods. This makes it an essential ingredient for manufacturers in the food and beverage industry, as well as a useful reducing agent in other technical applications.

Application

• Food Preservation: Primary use as an antioxidant in processed meats (like cured meats and sausages), canned fruits and vegetables, jams, and beverages to prevent browning and spoilage.
• Beverage Industry: Used in wines, beers, and fruit juices to inhibit oxidation, stabilize color, and prevent the formation of undesirable compounds.
• Pharmaceutical & Cosmetic Auxiliary: Acts as an antioxidant in certain pharmaceutical formulations and cosmetic products to enhance stability.
• Industrial Reducing Agent: Employed in various chemical processes, including photography and dye manufacturing, where a mild reducing agent is required.

Quality Control

Our Erythorbic Acid is produced and tested to meet stringent quality standards, including FCC (Food Chemicals Codex) grade specifications, ensuring its safety and suitability for food applications. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent caking and degradation. For long-term storage, consider using an inert atmosphere to minimize oxidation.
