Calcium Propionate To Retain Freshness

Calcium propionate is a salt of propionic acid, a naturally occurring organic acid. It is produced industrially by reacting propionic acid with calcium carbonate or calcium hydroxide. This process yields a white crystalline powder.

Manufacturers add calcium propionate to foods as a preservative to inhibit the growth of mold and bacteria. It is most commonly found in baked goods such as breads, rolls, and pastries, helping to extend their shelf life and maintain freshness. It is also used in some cheeses and processed meats.

Calcium propionate is generally recognized as safe (GRAS) by the FDA for use as a food additive. It is metabolized by the body in a similar way to other carbohydrates. JECFA (Joint FAO/WHO Expert Committee on Food Additives) has evaluated calcium propionate and established an acceptable daily intake. Some studies have explored potential links between propionates and behavioral effects in children, but evidence is mixed and not conclusive.
