Calcium propionate

Calcium propionate (also known as E282 or calcium propanoate) is a common food additive and preservative used primarily to inhibit the growth of mold and bacteria, thus extending the shelf life of various products.
Applications: It is widely used in yeast-leavened bakery goods (like commercial bread, pastries, and rolls), as well as certain dairy products (cheeses, whey) and processed meats.
Form: It is typically found as a white powder or crystalline solid.
Production: Industrially, it is produced from the reaction of calcium oxide and propionic acid.
