Innumerable percentage of the world population suffers from shortage of vitamins and minerals which is usually called malnutrition. Enough perception and access of such essential vitamins and minerals have close relationship with eternity, physical and mental developments, good health, general welfare of individuals and societies. In this research, the fortification of yogurt with iron has been studied. The kinds of iron used in this study include: FeCl3 (H2O)6, The whey protein-chelated iron (Fe-WP) and The Fe-Casein complex (Fe-CN) that each of them were evaluated in three quantities (10, 20 and 40 milligrams per one kilogram of milk). Then their chemical experiments and organoleptic specifications were studied after keeping 21 days in refrigerator and their results were reported. Results showed that all of these iron compounds were suitable for yogurt but two complexes of iron, including Fe-WP and Fe-CN, were better to be used.
