Folic acid fortification of double fortified salt

Abstract The addition of folic acid to Double Fortified Salt (with iron and iodine) aims simultaneously ameliorate three major micronutrient deficiencies in vulnerable populations. To make Triple Salt, we added the iodine solution (first method) premix (second that are used fortify salt with iodine. When through solution, sodium carbonate was needed dissolve adjust pH. Alternately, either core or sandwiched between TiO 2 layer premix. Folic were stable all cases, retaining more than 70% micronutrients after six months at 45 °C/60–70% relative hu. Adding premix's is preferred as retention slightly higher, did not impact salt's colour. additional cost for adding about 27¢/person per year. fortified made method cooking affect selected cooked foods' sensory properties. technology a cost-effective approach combating iron, iodine, deficiencies.
