Determination Of Iodine Concentration in Table Salt Consumed in Nigeria

Ezeh, JN, and Ikeyi, AP

Abstract

In Nigeria, the consumption of iodized salt plays a vital role in preventing iodine deficiency disorders, which are a significant public health concern. However, there is growing uncertainty about the actual iodine content in various salts produced and consumed across the country. This study analyzed the iodine concentrations in four salt samples (Uncle Palm Salt, Dangote Salt, Royal Salt and Sea Salt). The salt samples were collected from a commercial market in Enugu State, Nigeria. Accordingly, iodometric titration method was used to analyze the iodine content of the salt samples and from the result of the analysis, the salts showed varying concentrations of iodine ranging from Uncle Palm Salt (1.076 mg/g), Dangote Salt (1.633 mg/g), Royal Salt (1.473 mg/g), and Sea Salt (1.010 mg/g). This result reveals distinct variations crucial for public health. Dangote Salt met and slightly exceeded WHO's recommended iodine fortification range of 1.0– 1.5 mg/g, making it a reliable iodine source. Royal Salt also showed adequate levels, while Uncle Palm and Sea Salt had comparatively lower concentrations, potentially inadequate depending on intake. Variations are linked to environmental conditions, packaging quality and iodine formulation. The study underscores the need for stringent quality control and consistent iodine fortification practices to combat iodine deficiency disorders. Ongoing monitoring and further research into iodine stability during storage are recommended to enhance the effectiveness of iodized salt in public health strategies.
