What it is

Ascorbic acid is a naturally occurring organic compound with antioxidant properties, commonly known as Vitamin C. It is found in many fruits and vegetables and can also be produced synthetically for use in food and supplements.

Why it's used

In foods, ascorbic acid is primarily used as an antioxidant to prevent spoilage, maintain freshness, and preserve the color of products. It also serves as a nutrient to fortify foods with Vitamin C, appearing often in cereals, processed fruits, and snack mixes.

Health notes

Ascorbic acid is generally recognized as safe (GRAS) by the FDA when used in accordance with good manufacturing practices. As an essential vitamin, it plays a vital role in human health. JECFA has evaluated ascorbic acid and did not set a numeric acceptable daily intake (ADI not specified), considering it safe for use as a food additive. EFSA has also evaluated its safety. There are no notable controversies regarding its safety at typical intake levels in food.
