Introduction:
Calcium propionate is an organic salt formed by the reaction of calcium hydroxide with propionic acid (also known as propanoic acid). Its chemical formula is Ca(OOCCH2CH3)2. The compound occurs in either crystalline or powder form. It is soluble in water and only very slightly soluble in alcohol.
Calcium propionate is used as a food preservative in breads and other baked goods because of its ability to inhibit the growth of molds and other microorganisms. It is not toxic to these organisms, but does prevent them from reproducing and posing a health risk to humans.
Propionic acid occurs naturally in some foods and acts as a preservative in those foods. Some types of cheese, for example, contain as much as 1% natural propionic acid.
