What it is

Ascorbic acid is a synthetic form of Vitamin C. It is typically made by combining glucose (a sugar) with other chemicals in a multi-step process.

Why it's used

Ascorbic acid is added to foods as an antioxidant to prevent spoilage and maintain color. It's commonly found in processed meats, baked goods, sauces, and beverages.

Health notes

The U.S. Food and Drug Administration (FDA) recognizes ascorbic acid as Generally Recognized As Safe (GRAS) when used as a food additive. It is an essential nutrient for human health, but high doses can cause digestive upset. International bodies like the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated ascorbic acid, and it is widely used globally.

Allergen info

Ascorbic acid is not derived from any of the nine FDA major allergens. It does not contain gluten.
