What it is

Erythorbic acid is a food additive that is an isomer of ascorbic acid (Vitamin C). It is produced commercially by the fermentation of a sugar source, typically glucose, using specific microorganisms.

Why it's used

Manufacturers use erythorbic acid primarily as an antioxidant to preserve color and flavor in foods. It helps prevent spoilage and maintain the desired appearance in products like cured meats, beverages, baked goods, and processed fruits and vegetables.

Health notes

Erythorbic acid is generally recognized as safe (GRAS) by the FDA for use as a food additive. It is metabolized differently than Vitamin C and does not provide the same vitamin activity. International bodies like JECFA and EFSA have evaluated erythorbic acid and its salts, and have established acceptable daily intakes. Evidence does not suggest adverse health effects at typical dietary levels.

Allergen info

Erythorbic acid is not derived from any of the major allergens recognized by the FDA. It does not contain gluten.
