Calcium Chloride Onion

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 powder.

Manufacturers add calcium chloride to foods as a firming agent, helping to maintain texture, especially in canned fruits and vegetables. It is also used to enhance flavor, such as in pickles and olives, and can be added to cheese making and beer brewing.

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