• Description: Calcium propionate, also commonly known as calcium propanoate, is a white powder that has a faint smell. The compound is stable at room temperature. It is hygroscopic and incompatible with strong oxidizing agents. It has a melting point of 300°C and a pH value of 7 to 9. It is slightly soluble in alcohol and fully soluble in water.Calcium Propionate as the newer food antifungal agent, is the calcium salt of propanoic acid which is a antifungal agent. It appears as white crystalline or powder, odorless or having slight specific odor of propionic acid, stable under light and heat , hygroscopic, soluble in water while aqueous solution is alkaline, slightly soluble in methanol and ethanol, not soluble in benzene and acetone. It is deliquescent in moist air and loses crystal water when heated to 120°C .It changes phase at 200~210°C and decomposes to calcium carbonate at 330~340°C . Under acidic conditions, it generates free propanoic acid which is weaker than sorbic acid while stronger than acetic acid, and has an antibacterial effect on Aspergillus niger and gas bacillus rather than yeast . Calcium Propionate is a normal intermediate product of animal metabolism and is safe eaten by animals. It has a broad antibacterial activity to mold bacteria and yeast bacteria, inhibiting the propagation of microorganisms, preventing feed molding, which can be used as a fungicide on food and feed and a preservative for bread and pastries. As a feed additive ,it can effectively prevent feed molding and prolong shelf life of feed . If combined with other inorganic complexes, it can also improve the appetite of livestock, increase milk production in cows, and its dosage is less than 0.3% of the combined feed (use propionic acid to count). Calcium 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.
• Uses: In Food During dough preparation, calcium propionate is added with other ingredients as a preservative and nutritional supplement in food production such as bread, processed meat, other baked goods, dairy products, and whey.? Calcium propionate is mostly effective below pH 5.5, which is relatively equal to the pH required in the dough preparation to effectively control mold. Calcium propionate can assist in lowering the levels of sodium in bread.? Calcium propionate can be used as an browning agent in processed vegetables and fruits.? Other chemicals that can be used as alternatives to calcium propionate is sodium propionate.? In Beverage Calcium propionate is used in preventing the growth of microorganisms in beverages.? In Pharmaceuticals Calcium propionate powder is utilized as an anti-microbial agent.it is also used in retarding mold in key aloe vera holistic therapy for treating numerous infections. Large concentrations of aloe vera liquid that is normally added to feel pellets cannot be made without using calcium propionate to inhibit mold growth on the product.? In Agriculture Calcium propionate is used as a food supplement and in preventing milk fever in cows. The compound can also be used in poultry feed, animal feed, for instance cattle and dog food. It is also used as a pesticide.? In Cosmetics? Calcium propionate E282 inhibit or prevent bacterial growth, therefore protect cosmetic products from spoilage. The material is also used in controlling the pH of personal care and cosmetic products. Industrial Uses Calcium propionate is used in paint and coating additives. It is also used as plating and surface treating agents.? In Photography? Calcium propionate is used in making photo chemicals and photographic supplies. Calcium 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.
