What it is

Ascorbic acid, also known as Vitamin C, is a naturally occurring nutrient found in many fruits and vegetables. It is typically produced industrially through a process that begins with glucose, often derived from corn.

Why it's used

Ascorbic acid is added to foods as an antioxidant to prevent spoilage and maintain color, especially in processed fruits and vegetables. It also functions as an acidity regulator and is commonly found in beverages, baked goods, and frozen foods.

Health notes

Ascorbic acid is generally recognized as safe (GRAS) by the FDA for use in food. It is an essential nutrient for human health. International bodies like JECFA and EFSA have evaluated ascorbic acid. While high doses can cause digestive upset in some individuals, it is not associated with significant health concerns at typical dietary intake levels.

Allergen info

Ascorbic acid is not one of the FDA's nine major allergens and does not contain gluten.
