Abstract
The Natl. Inst. of Nutrition (NIN), Hyderabad, developed iodine and iron double-fortified salt (DFS) as "one intervention controlling two problems," namely, iodine deficiency disorders (IDDs) and iron deficiency anemia (IDA). NIN-DFS contains foodgrade common salt with low magnesium and high NaCl, potassium iodate, ferrous sulfate heptahydrate, and sodium hexametaphosphate(SHMP) as a stabilizer, and 30 ppm iodine and 1000 ppm iron. Large-scale production in factories is by dry-mixing powdered salt with iodine and iron compounds. The stability of iodine and iron in this salt has been shown to be more than 1 y. Organoleptic trials with commonly consumed Indian foods indicated good acceptability. Human metabolic studies showed excellent bioavailability of iron and iodine. Biosafety studies confirmed the safety of NIN-DFS. Epidemiological studies showed significant reduction in the prevalence of total goiter and anemia. The cost of 1 kg NIN-DFS works out to be 1 rupee (0.025 US$) more than that of iodized salt. A high-power committee, constituted by the Ministry of Health and Family Welfare, Government of India, recommended the introduction of NIN-DFS in nutrition programs. Establishment of the specifications under the Prevention of Food Adulteration Act (PFA; 2008), Government of India and the standards of the Bureau of Indian Standards (BIS) are in progress. A memorandum of understanding (MoU) is being signed for free technology transfer between NIN and salt manufacturers who would supply at least 20% of the produce to the Government for distribution through the public distribution system for the benefit of people living below the poverty line at a price fixed by the Government.
