ABSTRACT

IDD (Iodine deficiency disorders) are recognised as a major global public health problem; it is possible to root out this problem by universal salt iodisation. The study was designed to determine iodine concentration in different branded salt from different areas of India. All samples were from various states of India. Concentration of iodine in salt was determined by both titrimetrically and spectrophotometrically. The branded salts doesn’t contain adequate amount of iodine as per the indication mentioned in the sample. Additional iodine supplements should taken along with the diet to prevent iodine deficiency disorder. In our country, despite improvements in salt production and marketing technology, the quality of available salt is poor, or salt is incorrectly iodised, or may deteriorate due to excessive or long term exposure to moisture, light, heat and contaminants. So that the process of iodisation is essential for salts. The qualitative and quantitative analysis of iodine present in various brands of table salt helps to correct this problem for an extend. Since iodine plays an important role in the production of thyroid hormones in our body as well as it is the major factor that reduce the iodine deficiency disorders too.Various brands of table salt were collected and the quantitative estimation of iodine was done by both titrimetic analysis and uv spectroscopy. Iodometry is an important redox titration method where the iodine reacts directly, and quantitatively with the salts. Due to high sensitivity and less time consuming UV spectroscopy is also used for the iodine determination in table salt. Hence this study aims the determination of iodine content in different branded table salts in India. It also aims to compare quality of various branded salts and thus aware the people about iodine deficiency disorders.
