Calcium Propionate A Preservative

Calcium propionate is a salt of propionic acid, a naturally occurring fatty acid found in some foods. It is manufactured industrially by reacting propionic acid with calcium carbonate or calcium hydroxide. It appears as a white powder or crystals.

Manufacturers add calcium propionate to foods primarily as a preservative to inhibit the growth of mold and bacteria. It is commonly found in baked goods such as breads, cakes, and pastries, helping to extend their shelf life.

In the United States, calcium propionate is generally recognized as safe (GRAS) by the FDA when used as a food preservative. Regulatory bodies like JECFA and EFSA have evaluated it. Studies on the effects of calcium propionate at typical dietary intake levels have not shown adverse health effects in most people. Some research has explored its potential role in behavior in children, but evidence is mixed and not conclusive.
