Iodine deficiency disorders (IDD) and iron deficiency anemia (IDA) often coexist. Double fortification with iodine and iron can be applied for coping those two major micromineral deficiencies. Unfortunately iodine is easily oxidized. This study was conducted to identify the stability of double fortification of salt with iron (NaFeEDTA) and iodine (potassium iodate/KIO3) in different storage conditions. The concentration variations were 0 (control) 0.0002 0.0005 and 0.1 of NaFeEDTA in fortified salt. All samples were stored for 28 days in opened and closed storage. Iodine concentration was analyzed with iodometric titration method at day of 0 7 14 21 and 28. The results showed iodine retention after 28 days of storage declined. In opened storage iodine retention in NaFeEDTA 0 0.02; 0.05 and 0.1 was 61.76 60 0.59 69.48 and 76.76 respectively from baseline iodine content. Meanwhile in closed storage the iodine retention on the same concentrations was higher namely 83.40 0.8296 0.8433 and 82 0.62 respectively. Both of storage conditions showed there was no effect of concentration variations of NaFeEDTA on iodine stability (p0.05). Double fortification with iodine and iron in form of NaFeEDTA had good stability especially if salt was stored in closed condition.

Abstract

Iodine deficiency disorders (IDD) and iron deficiency anemia (IDA) often coexist. Double fortification with iodine and iron can be applied for coping those two major micromineral deficiencies. Unfortunately iodine is easily oxidized. This study was conducted to identify the stability of double fortification of salt with iron (NaFeEDTA) and iodine (potassium iodate/KIO3) in different storage conditions. The concentration variations were 0 (control) 0.0002 0.0005 and 0.1 of NaFeEDTA in fortified salt. All samples were stored for 28 days in opened and closed storage. Iodine concentration was analyzed with iodometric titration method at day of 0 7 14 21 and 28. The results showed iodine retention after 28 days of storage declined. In opened storage iodine retention in NaFeEDTA 0 0.02; 0.05 and 0.1 was 61.76 60 0.59 69.48 and 76.76 respectively from baseline iodine content. Meanwhile in closed storage the iodine retention on the same concentrations was higher namely 83.40 0.8296 0.8433 and 82 0.62 respectively. Both of storage conditions showed there was no effect of concentration variations of NaFeEDTA on iodine stability (p0.05). Double fortification with iodine and iron in form of NaFeEDTA had good stability especially if salt was stored in closed condition.
