Calcium propionate is a calcium salt of propionic acid, a carboxylic acid. It is used as a food additive for its preservation properties.
Function: Calcium propionate acts as a preservative by inhibiting the growth of molds and yeasts in foods. It thereby helps extend the shelf life of food products.
Applications: It is commonly used in the food industry, especially in the production of bakery products such as bread. It can also be used in other products like dairy, confectionery, cereals, and more.
Mode of Action: Calcium propionate works by releasing propionic acid into foods, creating an inhospitable environment for molds and yeasts, thus inhibiting their growth.
Safety: Calcium propionate is generally recognized as safe (GRAS) when used in accordance with good manufacturing practices. It has been evaluated by health authorities and approved as a food additive in many regions worldwide.
Labeling: When used in food products, calcium propionate must be listed in the ingredient list on the label.
Usage Limits: There are regulatory limits on the amount of calcium propionate that can be used in foods to ensure consumer safety.
Alternatives: Other food preservatives can also be used in combination with or as alternatives to calcium propionate, depending on the specific requirements of the product.
