Abstract

The amount of iodine necessary for our body can be achieved by the consumption of iodized salt.   This study aimed to determine the iodine content and its exposure to the commercially available iodized salt product in the supermarkets of Woldia town, Ethiopia. The study was conducted by collecting five different salt products from the supermarket and the iodine content was determined by both iodometric and UV-Vis spectrophotometric methods. The iodine content of salt samples measured with the UV-Vis Spectrophotometric and Iodometric titration method were found to be in the ranges of 11.33±2.588 to 31.73±1.726 ppm. From all salt products 60% (brand 2, brand 3, and brand 5) were adequately iodated (15- 45 ppm) while 40% (brand 1 and brand 4) were under the standard limit (<15 ppm). The iodine exposure at low level of consumption during cooking ranged from 68.03±15.62 to 190.35±12.69 μg/day while 90.61±25.36 to 253.8±16.92 μg/day for medium consumption, 113.43±31.97 to 162.15±12.21 μg/day for moderate high salt consumption and 135.92±38.04 to 194.82±14.86 μg/day for high salt consumption. In this study, UV-Vis Spectrophotometer was successful applied for iodine analysis in salt sample.
