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 propionate 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, typically at 0.1-0.4% (though animal feed may contain up to 1%).
