Calcium propionate is the salt of propionic acid and calcium. this product also commonly known as calcium propanoate and is used as a food preservative and found in very food such as commercial bread, processed meat, whey & etc.

It is added to the dough to prevent bread mold in the bread production process. By prohibiting mold and bacterial growth, calcium propionate extends the normal shelf-life of bread and baked goods.

The use of this material, especially in industrial food products, which is offered in large-scale production in stores, helps to maintain them and prevents the growth of mold.

Although the use of calcium propionate increases the shelf life by preventing the growth of mold and bacteria, it is better to use it in the case of bakery products with yeast because calcium ions interfere with the chemical agents in bakery products without yeast.

 Reactions and production

Calcium propionate is used as a mold inhibitor in various dairy products, animal feed as well as in agricultural applications. It is a natural salt available in small quantities in many food items. It is formed by reacting calcium hydroxide and propionic acid. Calcium propionate is available in powder, liquid and compressed form.



Calcium propionate used as a food additive E282. also, its used as a food preservative to help preserve various food products, including

  • Baked goods: breads, pastries, muffins, etc.
  • Dairy products: cheeses, powdered milk, whey, yogurt, etc.
  • Beverages: soft drinks, fruit drinks, etc.
  • Alcoholic drinks: beers, malt beverages, wine, cider, etc.
  • Processed meats: hot dogs, ham, lunch meats, etc.

It is added during the dough production phase and concentration is dependent on the item and desired shelf life. This compound is often used in bakery products as a mold inhibitor, as much as 0.1 to 0.4%  based on the relative weight of the flour (although animal feed may contain 1%).

Calcium propanoate in BREAD

Is it Vegan?

Yes. calcium propionate made from the chemical reaction. And the raw materials without of animal origin.


Various studies have been conducted to investigate the potential toxicity and the possibility of cancer on this substance. In most cases, laboratory findings were negative.

“There is no evidence in the available information on propionic acid, calcium propionate, and sodium propionate that demonstrates or suggests reasonable grounds to suspect a hazard to the public when they are used at levels that are now current or that might reasonably be expected in the future.”

Calcium propionate is not stored in the cells of the body. The digestive system of the human body separates calcium from propionic acid when digesting food, which, like other fatty acids, is easily absorbed and metabolized, and then your body destroys it.

In rare situations, it may cause adverse effects, such as headaches and migraines .
