A survey of selected minerals in ready-to-eat pastırma types from different regions of Turkey using-ICP/OES


Abstract: The aim of this study was to assess the content of selected minerals (Ca, K, Na, Mg, S, P, Pb, Zn, Mn, Fe, and Ni) and moisture values in types of pastırma (sırt, kuşgömü, bohça, and şekerpare), a dry-cured meat product. Forty-four samples of pastırma were collected from Turkey and analyzed using inductively coupled plasma-optical emission spectrometry (ICP/OES) for quantitative determination. Na content was the highest out of all the other minerals in all the pastırma types (31.9-47.7 g kg^{-1} dry weight). The determined mean ranges of heavy metals were 2.6 ± 0.5 to 3.6 ± 0.8 Pb, 245.3 ± 102 to 323.4 ± 92 Zn, 2.8 ± 2.4 to 3.9 ± 1.8 Mn, 69.7 ± 25 to 81.6 ± 15 Fe, and 0.9 ± 0.3 to 1.2 ± 0.5 Ni mg kg^{-1} dry weight. Significant differences among the types of pastırma were observed in Ca (P < 0.05), K (P < 0.05), Mg (P < 0.05), Na (P < 0.01), Pb (P < 0.01), S (P < 0.05), and Zn (P < 0.01), while there was no difference in the amounts of Fe, Mn, Ni, and P among types of pastırma (P > 0.05). Moisture values of kuşgömü were lower than those of the other types of pastırma (P < 0.05).
