The effect of meal composition, cooking, drying and fortification on in vitro iron availability from meals (50% meat, 50% vegetables) and meat was studied. Fortification was carried out with electrolytic iron powder. Unfortified samples were also studied. In fortified meals, iron availability (8.5% in raw sample) was not affected by cooking and drying processes. However, cooking and drying reduced chemical availability of iron in unfortified meals. Similar results were obtained with meat: upon cooking its iron availability showed a reduction of 26% and 4%, in unfortified and fortified samples, respectively. Therefore, fortification reduced losses due to processing. Presence of vegetables (50%) reduced dialyzable iron by 35%.
