  abstract = {{F}ortified rice holds great potential for bringing essential micronutrients to a large part of the world population. {T}he present study quantified the losses of three different micronutrients (vitamin {A}, iron, zinc) in fortified rice that were produced using three different techniques (hot extrusion, cold extrusion, and coating) and stored at two different environments (25 +/- 5 degrees {C} at a humidity of 60% and 40 +/- 5 degrees {C} at a humidity of 75%) for up to one year. {F}ortified rice premix from the different techniques was mixed with normal rice in a 1:100 ratio. {E}ach sample was analyzed in triplicate. {T}he study confirmed the high stability of iron and zinc during storage while the retention of vitamin {A} was significantly affected by storage and the type of techniques used to make rice premix. {L}osses for iron and zinc were typically < 10% for any type of rice premix. {A}fter 12 months at mild conditions (25 degrees {C} and humidity of 60%), losses for vitamin {A} ranged from 20% for cold extrusion, 30% for hot extruded rice 77% for coated rice premix. {A}t higher temperatures and humidity, losses of vitamin {A} were 40%-50% for extruded premix and 93% for coated premix after 6 months. {W}e conclude that storage does lead to a major loss of vitamin {A} and question whether rice is a suitable food vehicle to fortify with vitamin {A}. {F}or {C}ambodia, fortification of rice with iron and zinc could be an effective strategy to improve the micronutrient status of the population if no other food vehicles are available.},
