description

Sodium propionate is a white crystalline solid, also known as sodium propanoate, which is the sodium salt of propionic acid. It is commonly utilized as a food preservative and flavoring agent due to its ability to inhibit the growth of mold and certain bacteria. Sodium propionate is recognized as generally recognized as safe (GRAS) by the FDA.
