What it is
Calcium dioxide is a white powder made from calcium oxide, which is produced by heating calcium carbonate (limestone). It is a chemical compound that reacts with water to form calcium hydroxide. It is sometimes referred to as slaked lime.
Why it's used
Manufacturers use calcium dioxide as an acidity regulator and firming agent in foods. It helps control the pH of products and can improve the texture of fruits and vegetables during processing. It is found in baked goods, snacks, and frozen food items.
Health notes
In the United States, calcium dioxide is generally recognized as safe (GRAS) by the FDA when used for its intended purpose. It is a source of calcium, which is an essential nutrient. International bodies like JECFA have evaluated calcium dioxide and established acceptable daily intake levels. Evidence does not suggest adverse health effects at typical dietary levels.
Allergen info
Calcium dioxide is not derived from any of the nine major allergens recognized by the FDA. It does not contain gluten.
