Fortification of food
items such as wheat flour, bread, milk, sugar, drinking water and common salt
are in practice in different parts of the world.
Iodised salt: Common salt has been selected as a suitable vehicle for fortification of iodine to control IDD(Iodine Deficiency Disorder). The technology involved in fortification of salt with iodine involves either dry mixing or spray mixing of salt with iodine source mainly with potassium iodate. It is an economical, convenient and effective means of mass prophylaxis in endemic areas.
Double fortified salt:
disorders and iron deficiency anaemia are widely prevalent and often coexist in
the country. Fortification of food with iodine and iron is recommended as one
of the strategies to prevent and control these two deficiency disorders. NIN
has developed a suitable technology for dual fortification of common salt with
iodine and iron. The stability of iodine is satisfactory in double fortified
salt with very little loss of iodine in six months.
