What it is

Calcium propionate is a salt of propionic acid. It is a white crystalline powder that is soluble in water. It is produced commercially by the reaction of calcium hydroxide with propionic acid.

Why it's used

Calcium propionate is used as a preservative in baked goods to prevent the growth of mold and bacteria. It helps extend the shelf life of bread, cakes, and other bakery products. It is commonly found in breads, rolls, and pastries.

Health notes

Calcium propionate is generally recognized as safe (GRAS) by the FDA for use as a food additive. It is also approved for use in the European Union. JECFA has evaluated calcium propionate and established an acceptable daily intake. Some studies suggest it may affect behavior in children, but the evidence is mixed and more research is needed. At typical consumption levels found in food, it is not considered harmful.

Allergen info

Calcium propionate is not derived from any of the nine FDA major allergens. It does not contain gluten.
