Calcium propionate (C6H10O4Ca) is a white crystalline organic salt that is soluble in water, ethanol, and acetone. It works by disrupting the cellular metabolism of microorganisms and preventing their growth and reproduction. It is a food preservative that inhibits the growth of mold, bacteria, algae, viruses, and fungi in various food products. It preserves the nutritional value of food products by reducing the need for higher heat treatments or other preservation methods that can degrade nutrient content. It helps in maintaining the freshness, texture, and appearance of food products to improve their overall quality. It also aids in enhancing food safety, extending shelf life, preventing spoilage, minimizing food waste, and reducing the risk of developing food borne illness.
