Multi-micronutrient (MN)-fortified fish cracker could be used as a means to improve iodine, iron (Fe) and zinc (Zn) status. We evaluated iodine stability as well as the quality and sensory properties of MNfortified fish cracker, at the fortification levels of 5.3 mg per 100 g for Fe and Zn and 260 lg per 100 g for iodine in the dough. On average, the overall retention of iodine after processing and storage for 4 months was~65%. Fortification with KIO 3 + ZnO, or KIO 3 + ZnO + ferrous fumarate, significantly increased the loss of iodine during processing. The Fe compounds tended to promote iodine instability during storage and contributed to thiobarbituric reactive substances. Fortification did not affect linear expansion of the cracker. Triple-fortified fish cracker with KIO 3 , ferric pyrophosphate and ZnO exhibited both high iodine retention (92.7% for steaming + drying and 72.7% for storage) in the tropical conditions (30 AE 1°C, 80 AE 5% R.H.) and achieved overall desirable sensory scores. Thus, such fortification of fish cracker might successfully supplement iodine, zinc and iron, while at the same time contributing to the palatability of cracker.
