摘要: The unexpectedly low bioavailability in humans of elemental iron powder prompted us to search for other Fe compounds suitable fortification flour that fulfill the two requirements insolubility water (due high content flour) and good humans. Systematic studies compatibility, solubility, led this study a microcrystalline complex ferric orthophosphate (CFOP), Fe3H8(NH4)-(PO4)6.6H2O, well-defined compound. This compound was labeled with 59Fe, native meals 55FeCl3. ratio absorbed 59Fe 55Fe is direct measure fraction CFOP joins nonheme pool made potentially available absorption. relative varied from 30% 60% when wheat rolls were served different meals. meets practical an fortificant well, regard both compatibility
