Speciation of bioaccessible (heme, ferrous and ferric) iron from school menus

Abstract A spectrophotometric method using batho-phenantroline as reagent has been optimized for iron speciation [ionic Fe(II) and Fe(III)] in the mineral soluble (bioaccessible) fraction obtained from the in vitro digestion of food dishes. The effect of the precipitant and reducing reagents, and th...

520			\|a Abstract A spectrophotometric method using batho-phenantroline as reagent has been optimized for iron speciation [ionic Fe(II) and Fe(III)] in the mineral soluble (bioaccessible) fraction obtained from the in vitro digestion of food dishes. The effect of the precipitant and reducing reagents, and the amount of sodium nitrite added was studied. Heme-Fe was estimated by subtraction of ionic Fe from the total bioaccessible Fe (determined by atomic absorption spectrometry). The method was applied to 13 dishes included in school menus. Soluble Fe was mainly in ionic form (49–100%). With the exception of spinach and potato omelets, a significant linear correlation (r=0.92) was obtained between Fe(II) and bioaccessible Fe. The Fe(II)/Fe(III) ratio increased with increasing meat protein content in the dish. In the analyzed dishes, heme-Fe content depended on meat content and also on the processing procedure applied.

The effect of the precipitant and reducing reagents, and the amount of sodium nitrite added was studied. Heme-Fe was estimated by subtraction of ionic Fe from the total bioaccessible Fe (determined by atomic absorption spectrometry). The method was applied to 13 dishes included in school menus.

abstract	Abstract A spectrophotometric method using batho-phenantroline as reagent has been optimized for iron speciation [ionic Fe(II) and Fe(III)] in the mineral soluble (bioaccessible) fraction obtained from the in vitro digestion of food dishes. The effect of the precipitant and reducing reagents, and the amount of sodium nitrite added was studied. Heme-Fe was estimated by subtraction of ionic Fe from the total bioaccessible Fe (determined by atomic absorption spectrometry). The method was applied to 13 dishes included in school menus. Soluble Fe was mainly in ionic form (49–100%). With the exception of spinach and potato omelets, a significant linear correlation (r=0.92) was obtained between Fe(II) and bioaccessible Fe. The Fe(II)/Fe(III) ratio increased with increasing meat protein content in the dish. In the analyzed dishes, heme-Fe content depended on meat content and also on the processing procedure applied. © Springer-Verlag 2005

The effect of the precipitant and reducing reagents, and the amount of sodium nitrite added was studied. Heme-Fe was estimated by subtraction of ionic Fe from the total bioaccessible Fe (determined by atomic absorption spectrometry). The method was applied to 13 dishes included in school menus. Soluble Fe was mainly in ionic form (49–100%). With the exception of spinach and potato omelets, a significant linear correlation (r=0.92) was obtained between Fe(II) and bioaccessible Fe. The Fe(II)/Fe(III) ratio increased with increasing meat protein content in the dish. In the analyzed dishes, heme-Fe content depended on meat content and also on the processing procedure applied.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Iron speciation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Bioaccessibility</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Meals</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Dishes</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Amaro, Manuel Angel</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Barberá, Reyes</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Lagarda, María Jesús</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">European food research and technology</subfield><subfield code="d">Berlin : Springer, 1999</subfield><subfield code="g">221(2005), 6 vom: 10.
