Multi-element Analysis of Food by Microwave Digestion and Inductively Coupled Plasma-Atomic Emission Spectrometry

Effects of Iron Enrichment of Adzuki Bean (Vigna angularis) Sprouts on Elemental Translocation, Concentrations of Proteins, Distribution of Fe-Metalloproteins, and Fe Bioaccessibility

“…In addition, the accumulation of Fe in the roots and cotyledons was less favored (500 and 1000 µg Fe) when compared to the enrichment via FeCl 3 and FeSO 4 . On the other hand, the highest enrichment potential of the edible part of the plant was observed after cultivation with Fe III -EDTA mass up to 3000 µg.…”

“…Solubility of a protein depends on amino acid composition and results from thermodynamic equilibrium between the protein-protein interaction and the protein-solvent interaction; the solubility is related to the hydrophilicity-hydrophobicity balance. 4,44 The enrichment via Fe III -EDTA altered the distribution of albumins, globulins, and glutelins in the stems, thus causing a significant increase in globulin (134%) and glutelin (48%) concentrations and 30% downregulation of albumins.…”

“…40% of the world population have Fe deficiency or low hemoglobin levels. 3 According to the US Food and Drug Administration (FDA) regulations, the recommended dietary allowance for Fe is 18 mg. 4 Leguminous plants have major social and economic importance, being one of the main sources of proteins, plant-derived micronutrients, and minerals for the population. 5 Furthermore, beans are the vegetable sources with the largest total Fe amount.…”

“…Therefore, in this work was (i) produced Fe-enriched adzuki bean sprouts; (ii) evaluated the Fe accumulation and translocation in plants in various culture media (FeCl 3 , FeSO 4 , and Fe III -ethylenediaminetetraacetic acid (Fe III -EDTA)) enriched with different Fe masses (500, 1000, 2000, and 3000 µg); and (iii) evaluated the effects of the enrichment by means of 3000 µg Fe III -EDTA: on the distribution of Ca, Cu, Fe, K, P, Mg, S, and Zn in different parts of the plant (roots, stems, and cotyledons); on protein concentrations (albumins, globulins, prolamins, and glutelins) and their association with Fe in the edible part of the plant (stems); and on Fe bioaccessibility in the edible part of the plant (stems).…”

Determination of Cu, Fe, Mn and Zn by flame atomic absorption spectrometry in multivitamin/multimineral dosage forms or tablets after an acidic extraction

“…Copper, Fe, Mn and Zn are essential elements present in most of multivitamin/multimineral formulations due to their physiological importance and biological roles [2,3]. The development of reliable methods for the determination of elements in these supplements is an important issue because of their widespread * Corresponding author.…”
