Determining the Content of Iodine in National Agency of Food and Drugs Administration and Control (NAFDAC) Approved Table Salts

Abstract

The study was aimed at determining the content of iodine in NAFDAC approved Table Salts used in Nigeria. Three Table Salts brands namely: Dangote fine edible salt, Royal edible salt and Mr. Chef edible salt were purchased from retailer level in Makurdi, Benue State, Nigeria. Salt iodine content is one of the indicators which is used for a sustainable elimination of iodine deficiency as a public health problem. The iodine content of each of the three brands of salt sample were carried out using the titrimetric method. Potassium Iodide (KI) was used for salt iodization. Results showed that the Dangote fine edible salt contain 39.6 ppm  of iodine while the Royal edible salt contain 41.8 ppm  and the Mr. Chef edible salt contain 42.9 ppm. The result confirms that each of the three samples met the iodine content requirements approved by NAFDAC. However, the results obtained were generally lower than the value found at the production level (50 ppm) for each table salt. The results were within the acceptable range for human consumption 50 ppm to 30ppm.
