Product description

Sodium propionate is a common food additive that is industrially manufactured but also occurs in nature. Since it is toxic to mold and some species of bacteria, it is an especially effective additive in baked goods or other products that are susceptible to spoilage. It is a safe compound when encountered at the low levels found in food.

Sodium propionate is the salt form of propionic acid, which is an organic acid that is produced during the chemical degradation of sugar. It is a compound that is produced naturally in the body when certain fatty acids and amino acids are metabolized.

Chemically synthesized sodium propionate is most commonly used as a preservative in the food industry. It prevents the growth of mold and some bacteria, thereby prolonging the shelf life of packaged baked goods. According to the Code of Federal Regulations, sodium propionate is generally recognized as safe when used as a food additive. It is also used to prevent mold growth in packaged and processed cheese products. In addition, ammonium propionate is used as an additive in animal feed to prevent overgrowth of unwanted bacteria in the stomachs of livestock.
