Sodium Propionate (E281) is the sodium salt of propionic acid, widely used as a food-grade preservative. It appears as a white crystalline powder or granule with a slightly hygroscopic nature and a faint odor of propionic acid. Sodium Propionate is easily soluble in water and ethanol, making it highly suitable for incorporation into different food formulations. Its primary function is to inhibit the growth of mold and certain bacteria, especially in bakery and dairy products.
Chemically stable, safe, and effective, Sodium Propionate meets international food additive standards and is recognized for its reliability in extending shelf life without altering the taste or texture of food products.
