DOUBLE FORTIFIED SALT
The double fortification of salt with iron and iodine for simultaneous prevention of iron deficiency anemia and iodine deficiency disorders has been a goal of researchers for at least 20 years. Salt fortified with ferrous fumarate and potassium, iodide was reasonably stable and maintained its organoleptic properties, making it more likely to be acceptable to consumers.
