Calcium propionate or calcium propanoate has the formula Ca(C2H5COO)2. It is the calcium salt of propionic acid.
Purity:99.0%min
Stamdard:FCC IV
Packing : 25kg/bag.
Application: As a food additive, it is listed as E number 282 in the Codex Alimentarius. Calcium propionate is used as a preservative in a wide variety of products, including but not limited to bread, other baked goods, processed meat, whey, and other dairy products. In agriculture, it is used, amongst other things, to prevent milk fever in cows and as a feed supplement Propionates prevent microbes from producing the energy they need, like benzoates do. However, unlike benzoates, propionates do not require an acidic environment.
Calcium propionate is used in bakery products as a mold inhibitor. Mold contamination is considered a serious problem amongst bakers, and conditions commonly found in baking present near-optimal conditions for mold growth.
