Iodine is naturally occurring, non-metallic diatomic heaviest stable halogens, essential for thyroid hormone biosynthesis. It also has several physiological and metabolic functions including in plant system. Although, consumption of iodized salt has been adopted universally to counter iodine deficiency disorder, seaweeds are also known as one of the richest reservoirs of it. In India currently, about 76.3% of households are consuming adequately iodized salt, while 14% of the population continues to consume inadequately iodized salt and 8% nil iodine salt. ‘Pradhan Mantri Matsya Sampada Yojana’ a flagship program of Ministry of Fisheries, Government of India has proposed to introduce seaweed-based diet, thus iodinophyte seaweeds assume significant importance. The literature review has reported range of iodine content among the Indian seaweeds between 2.54 and 740 mg 100 gm−1DW, nevertheless, 26 taxa reported > 100 mg 100 gm−1DW of iodine. The total biomass availability of 31,238.9 fresh tons for 50 iodinophyte taxa (25 belonging to Rhodophyceae, 11 to Phaeophyceae and 14 to Chlorophyceae) has been reported. This mini review also discusses about stability and toxicity of iodine. |
