Sodium Propionate USP
Sodium Propionate also known as Sodium Propanoate is the sodium salt of propionic acid. It occurs as a white crystalline solid that is deliquescent in moist air. It is produced by the reaction of propionic acid on sodium carbonate or sodium hydroxide.
Sodium propionate is used in bakery products as a mold inhibitor. Propionates prevent microbes from producing the energy they need, like benzoates do. It is used as a food additive to prevent the growth of molds in bakery and other products. It is represented by the food labeling E number E281.
