title: Dry mixing technique for the large scale production of iodine fortified salt in India.
abstract: Dry mixing technique was used successfully in three factories in India for the manufacture of iodine fortified salt. Permitted food additives, calcium carbonate and magnesium carbonate, were used with potassium iodate. The technology was smooth and free from any problem. Since the formerly conventional, but now superceded on analytical performance criteria, spray-mixing system was not used in the study, plants of the economics either batch mixing or continuous processes were more in evidence, and could be compared with avoidable spray mixing production performance data. The iodine fortified salt was free-flowing and retained the colour of the common salt. The iodine distribution was uniform (about 30 ppm). Long distance road transportation did not affect the iodine stability and its consistency. Storage studies showed satisfactory stability and the fortified salt had prolonged shelf-life beyond one year.
