RESUMO
Iron deficiency is one of the most important nutritional problems in the world. The best method to overcome this problem is the fortification of foods with highly bioavailable iron. Fluid milk is a massive consumption food with an easy access and which is generally the only food intake during the first months of life. Therefore the fortification of fluid milk with highly biovalable iron and no detectable alterations of its sensorial characteristics was studied in the present work. This procedure was made possible using a new type of ferrous sulfate, stabilized and microencapsulated with soy lecithin (SFE-171). The iron concentration of the fortified milk is 12 mg per liter. In order study the iron absorption from milk fortifield with this product, SFE-171 was labeled with59 Fe and given to 29 volunteers with a normal iron status, each of which received an iron quantily of 3 mg in 250 ml of fluid milk. The average iron absorption was (10.2+4.7) per cent. This result shows that the iron given in this physiocochemical form has the advantage of a high biovailability and it is possible that this product will be the first attempt for an adequate solution of iron deficiency.
