Abstract: This study was conduct to identify the stability of salt double fortification with iron from NaFeEDTA and iodine from potassium iodate (KIO3) at different storage condition, open and closed condition. This research is pure experiment research use pre post with control design. There are 4 unit examinations (1 control group and 3 treatment groups). There are 4 concentration variation of NaFeEDTA 0%;0.02%; 0.05%; 0.1%. All examination units were stored for 1 month (28 days) at opened and closed storage. Iodine level was analyzed with iodometry titration method at day 0, 7, 14, 21, and 28.Results showed that Iodine retention after 28 days storage is decline. For close storage iodine retention on NaFeEDTA 0 %;0,02 %;0,05 %; dan 0,1 % are 83,40 %; 82,96 %; 84,33 %; 82,62 % constantly. For open storage are 61,76%, 60,59%, 69,48% and 76,76%. Statistic test show that there no efffect (p>0,05) on variation of NaFeEDTA concentration with stability of iodine.

Conclusions: Double fortification of salt with iodine and iron in the form of NaFeEDTA has an good stability especially if stored in a closed condition
