In developing countries, electrolytic iron and zinc oxide are often used in fortification-mixes (Allen, De Benoist, Dary, & Hurrell, 2006). This is because the effects of these compounds on the sensory quality of the food are low due to poor solubility, but it is possible to add more fortificant due to their low cost. However, this means fortified food contains large amounts iron that cannot be absorbed, but might increase the growth and virulence of pathogenic bacteria. Ferric sodium ethylenediaminetetraacetate (NaFeEDTA) is a popular fortificant because the iron is highly bioavailable, even in high phytate foods, so less has to be added. Also, addition of NaFeEDTA could increase zinc availability, but results from the limited research is contradictory with outcomes depending on the food vehicle (Bothwell & MacPhail, 2004).
