CHEMICAL AND PHYSICAL PROPERTIES OF THE FORTIFIED WHEAT FLOUR WITH SYNTHETIC FENAEDTA COMPLEX

Abstract

This study includes fortification of two type of flour 70 and 80 % extraction with two sources of non-haem iron sodium iron EDTA (FeNaEDTA) which was synthesis in laboratory and ferrous sulfate in level of 30 mg iron/kg flour. The synthesis FeNaEDTA has been identified in several methods, infra red spectrophotometry, C.H.N analyzer and inductively coupled plasma optical emission spectrometry (ICP- OES). NaFeEDTA is the only non-haem source that has good bioavailability as it is relatively independent of flour composition and withstands the inhibitory effects of phytates.
Chemical analysis of the two type of the flour before and after fortification with FeNaEDTA was done (moisture, ash , protein , fat and wet gluten)% and the amount of iron as mg/100g.The falling number was not affected by the above fortificants.The values of falling Number of 70% extraction for non-fortified and fortified flour by FeNaEDTA and ferrous sulfate were ( 425,426,427) second respectively, while for 80% extracted flour were (445,446,448) second respectively.
The color test showed an increasing of color degree upon fortified by iron sulfate and decreasing of upon fortified by FeNaEDTA in both type of flour.
