Calcium propionate is a white powder(s) or monoclinic crystal(s), crystallizes as the monohydrate in monoclinic plates and as the trihydrate. The anhydrous salt dissolves up to 41.7 wt % in water and is insoluble in ethanol. The aqueous solutions can cause inflammation. It is used to mold-retardant additive for bread, tobacco, pharmaceuticals, antifungal agent.[HAW93]

개요Calcium propanoate or calcium propionate has the formula Ca(C2H5COO)2. It is the calcium salt of propanoic acid. It is a preservative commonly used in baked goods around the world, where it extends their shelf life by inhibiting the growth of spoilage microorganisms, namely mold and ropy bacteria.

용도Calcium Propionate is the salt of propionic acid which functions as a preservative. It is the most widely used antimycotic in breadmaking. it is effective against mold, has limited activity against bacteria, and no activity against yeast. it is soluble in water with a solubility of 49 g/100 ml of water at 0°c and insoluble in alcohol. it is less soluble than sodium propionate. its optimum effectiveness is up to ph 5.0 and it has reduced action above ph 6.0. It is often utilized at about 0.2%, flour basis; higher concentrations lead to flavor problems and begin to inhibit yeast fermentation. it is used in bakery products, breads, and pizza crust to protect against mold and “rope.” it is also used in cold-pack cheese food and pie fillings. typical usage level is 0.2–0.3% and 0.1–0.4% based on flour weight.

일반 설명Calcium propionate is generally used as a food preservative in bread. It has also been reported to reduce milk fever in dairy cows. Calcium propionate is the most effective below pH 5.5. Below this pH, the active component, propionic acid, is undissociated and becomes active. The dough pH needs to be below 5.5 and well controlled to effectively control mold.
