What it is

Calcium chloride is a salt that occurs naturally as the mineral nadorite. It is typically produced industrially from limestone and salt. It is a white crystalline solid that is highly soluble in water.

Why it's used

Calcium chloride is used to firm fruits and vegetables in canned goods, preventing them from becoming mushy. It is also used in pickling to maintain crispness and in cheesemaking to help coagulate milk proteins. It can be found in canned beans, pickles, olives, and relishes.

Health notes

Calcium chloride is Generally Recognized As Safe (GRAS) by the FDA for use in food. It is a source of calcium and chloride ions, which are essential nutrients. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated calcium chloride and established an acceptable daily intake. It is not known to cause adverse health effects at typical dietary levels.

Allergen info

Calcium chloride is not a major allergen and does not contain gluten.
