Ascorbic Acid And Calcium Carbonate To Maintain Freshness

Ascorbic acid is a form of vitamin C, a nutrient naturally found in many fruits and vegetables. Calcium carbonate is a mineral, commonly known as chalk or limestone. In food processing, they are often used together to help keep sliced fruits and vegetables looking fresh by preventing browning.

Ascorbic acid and calcium carbonate are added to pre-packaged fruits and vegetables, like sliced apples, to act as an antioxidant and firming agent. This combination helps maintain the color and texture of the produce, making it more appealing to consumers. They can also be found in some wholesome snack products.

Ascorbic acid is recognized as safe (GRAS) by the FDA when used as a nutrient or for its functional properties. Calcium carbonate is also GRAS and is widely used as a calcium supplement and an antacid. Both are essential nutrients. International bodies like JECFA and EFSA have evaluated these substances. At typical intake levels found in food, they are not associated with adverse health effects.
