Calcium Propionate (E282)

Calcium Propionate Calcium propionate is manufactured by reacting propionic acid with calcium hydroxide, used as an antimicrobial preservative, mold inhibitor, and dough conditioner (INS 282) that inhibits mold/yeast/bacterial growth through propionate ion disruption of microbial metabolism while providing calcium nutrition and buffering. In the food industry, food-grade forms excel at extending shelf life in yeast-leavened bakery without affecting fermentation or taste.
