What it is

Ascorbic acid is a naturally occurring vitamin (Vitamin C) found in many fruits and vegetables. It is often produced commercially through a chemical synthesis process involving the fermentation of sugars.

Why it's used

Ascorbic acid is primarily used to maintain color in foods, preventing browning in fruits and vegetables. It also acts as an antioxidant, protecting fats and flavors from spoilage. It is commonly found in fruit juices, baked goods, cured meats, and processed fruits.

Health notes

Ascorbic acid is widely recognized as an essential nutrient (Vitamin C) for human health. The FDA lists it as Generally Recognized As Safe (GRAS) for use in food. While it is vital for immune function and collagen production, high doses can cause digestive upset in some individuals. International bodies like JECFA have evaluated its safety.

Allergen info

Ascorbic acid is not derived from any of the 9 FDA major allergens. It does not contain gluten.
