Consumer Advice ​

Sodium propionate is the sodium salt of propionic acid, used as a preservative in baked goods and cheeses to prevent mould and microbial growth. In the body it breaks down into propionic acid (a normal metabolite) and sodium, so it is safe at authorised levels. Most people experience no discomfort; those monitoring sodium intake should simply count its sodium content.
