Determining the microelement composition of poppy seeds using solidphase spectrophotometry method
Journal Title: Восточно-Европейский журнал передовых технологий - Year 2018, Vol 2, Issue 11
Abstract
<p>Poppy seeds are one of the most important and oldest oil-bearing crops in the world. Therefore, quality control of poppy seeds and food products whose composition contains them as a food additive, is very important. To this end, we have applied procedures for solid-phase spectrophotometric and photometric determining of micro elements in food products.</p><p>It was established that in determining cadmium and zinc, the best ion exchanger for the group concentration of interfering metal ions is the ion exchanger with the immobilized KO.</p><p> made it possible to concentrate and determine in the solid phase the ions of Hg(II). Using <strong> </strong>enabled selective determining of Pb(II).</p><p>Selective determining of the Fe(III) ions at pH 3 was conducted using ammonium thiocyanate. Cu(II) was determined photometrically upon masking the ions of Fe(III) employing SPADNS. Based on the data acquired, we have developed a microelement analysis scheme for poppy seeds.</p><p>It was established that the sample contained, mg/kg: Cu(ІІ) – 5.0; Pb(ІІ) – 0.3, Zn(ІІ) – 50, P(V) – 1,600, K − 550, Na – 20, Ca – 1,500, Mg(II) – 450; Fe(ІІІ) −10; Cd(ІІ) and Hg(ІІ) are absent.</p><p>The proposed scheme for analysis of poppy seeds is universal and could be applied for microelement analysis of other food products.</p><p>The procedures employed are characterized by sensitivity and selectivity.</p><p>Ion exchangers with the immobilized dyes, as well as procedures for the solid-phase spectrophotometric determining, are environmentally safe. They do not require the use of toxic organic reagents.</p><p>The procedures applied are easy to use.</p><p>Relative standard deviation in the results does not exceed 0.10. This indicates good reproducibility of the results.</p>
