Alternative Methods of Producing Iodized Salt

Abstract

Due to the high incidence of iodine deficiency diseases (IDD) in the Philippines, iodized salt has become quite popular on the market. The aim of this research project is to discover different methods of making cheap and accessible iodized salt. Different gadgets were designed to mix the salt and potassium iodate (KIO3) adequately. The iodometric titration method was used to test for the iodine content of the manufactured salt. To prove the efficiency and consistency of the gadget, the Analysis of Variance (ANOVA) test was performed. It has been shown that the iodine has been evenly distributed at 100 ppm, which is the standard amount. Thus, satisfactory results have been obtained. However, ways to improve the appearance and stability of the salt under storage may still be pursued.

Introduction

Iodine deficiency diseases (IDD) are very common in the Philippines, especially in the mountainous regions and in regions located in inland areas without direct access to the sea. In 1987, about 3.5 percent of the population was affected with IDD, according to the goiter prevalence survey done by Food and Nutrition Research Institute (FNRI).
