What it is

Calcium chloride is a salt made from chlorine and calcium. It is often produced industrially from limestone or as a byproduct of the Solvay process for making soda ash. It appears as white crystals or granules and dissolves easily in water.

Why it's used

Manufacturers add calcium chloride to foods to help maintain firmness, especially in canned fruits and vegetables. It can also be used as a flavor enhancer in some products, such as pickles and olives, and in cheesemaking to help coagulate milk proteins. It is commonly found in canned vegetables, frozen dinners, and pickled products.

Health notes

Calcium chloride is generally recognized as safe (GRAS) by the FDA for use in food. It is a source of calcium, an essential nutrient. International bodies like JECFA have evaluated calcium chloride. At typical dietary levels, it is not associated with adverse health effects.

Allergen info

Calcium chloride is not derived from any of the nine FDA major allergens. It does not contain gluten.
