Water Ascorbic Acid

Ascorbic acid is a form of vitamin C, an essential nutrient for human health. It is a white or slightly yellow crystalline powder that is soluble in water. It can be produced commercially through a process that starts with glucose, often derived from corn.

Ascorbic acid is commonly added to foods as an antioxidant to prevent spoilage and maintain color, especially in fruits and vegetables. It also acts as an acidulant, contributing a tart flavor, and can be used to fortify foods with vitamin C. It is found in beverages, baked goods, and processed fruits.

Ascorbic acid is generally recognized as safe (GRAS) by the FDA when used as a nutrient or dietary supplement. It is an essential vitamin, and while very high doses can cause digestive upset, typical dietary intake is considered safe. JECFA has evaluated ascorbic acid and established an acceptable daily intake. No numeric limit was specified by JECFA.
