Abstract: The present invention relates to stable and white iron fortification and iron+iodine double fortification agents, their preparation and use in fortification of salt. These agents help overcome the normal difficulties encountered in iron and iodine fortification such as low iodine stability on storage, development of colour and odour, and use of unwanted additives to impart stability. In one of the invented products, both iron and iodine coexist in stable manner in the same matrix which allow for a more uniform distribution of iodine. The process of preparation is demonstrated to be scalable and utilizes commonly available raw materials which would enable the products to be synthesized in affordable manner.

Abstract: A method for preparation of iodizing agent for the use in the formulation of iodized salt that offers excellent stability of iodine in iodized salt is developed and the unrefined salt iodized with this compound was tested for its stability in presence of moisture, temperature and metal salts at higher temperature. The hydrotalcite type layered compound was used to prepare such compound and part of carbonate was substituted with iodate anion. The iodizing agent exhibited excellent stability of iodine in iodized salt.
