Calcium Propanoate

Calcium propanoate is a salt of propanoic acid, a naturally occurring fatty acid found in some foods. It is typically produced industrially by reacting propanoic acid with calcium carbonate or calcium hydroxide.

Manufacturers add calcium propanoate to foods as a preservative to inhibit the growth of mold and bacteria. It is commonly found in baked goods such as bread, cakes, and pastries, as well as in processed cheeses and other food products where shelf life is important.

Calcium propanoate is generally recognized as safe (GRAS) by the FDA for use as a food additive. It is also approved in many other countries. JECFA has evaluated calcium propanoate and established an acceptable daily intake. Studies on propionates have not shown significant adverse health effects at typical consumption levels.
