Sodium erythorbate chemical structure
What is Sodium Erythorbate Used for in Food?
It is used as an antioxidant, a preservative and a curing accelerator, let’s see each function:
Antioxidant: it keeps the food fresh (color, flavor and etc) as sodium erythorbate itself can be oxidized by scavenging oxygen and then inhibiting the oxidation of fruits and vegetables.
Preservative: it prevents microbial growth and therefore extends the shelf life of food.
Curing accelerator: it accelerates the curing process of meat and fish products by speed up the development of the pink color.
