What is Erythorbic Acid?

Erythorbic acid (D-isoascorbic acid) is a stereoisomer of ascorbic acid (Vitamin C) with similar antioxidant properties but minimal vitamin C activity. As a reducing agent and oxygen scavenger, it prevents lipid oxidation and colour degradation in food and feed ingredients. Because it provides antioxidant protection without contributing significant vitamin C activity, it is used specifically as a technological antioxidant additive rather than a nutritional supplement.

Role in Animal Nutrition

Erythorbic acid is effective as a feed-grade antioxidant for protecting rendered fats, fish meals, and other lipid-rich ingredients during storage and processing. It prevents rancidity, colour changes, and vitamin destruction by scavenging oxygen and interrupting oxidative chain reactions. In pet food manufacturing, erythorbic acid protects the lipid fraction and maintains product colour stability. It is also used in meat ingredient processing to prevent myoglobin oxidation and colour change. As a cost-effective alternative to ascorbic acid for purely antioxidant applications, it is widely used in industrial food and feed production.
