Selenium content of chicken meat in Croatia

Abstract

The selenium content in dark muscle and liver was determined in chicken meat. All samples had been collected from three large meat producing companies in Croatia. The samples were wet digested with a mixture of nitric and perchloric acids. The selenium content was analyzed by hydride generation atomic absorption spectrometry with the recovery from 97.8 to 98.2%. The correlation coefficient of 0.976 was determined after comparison with results of the fluorimetric method. Mean +/- standard deviation of the selenium concentration (ng Se/g dry matter) was 1330 +/- 20, 2000 +/- 30 and 2090 +/- 30 in liver, and 560 +/- 50, 520 +/- 70 and 740 +/- 50 in dark muscle.

“…We can infer from the results that the highest concentrations of Se are found in the samples of kidney (1.186 µg/g, fresh weight), liver (0.638 µg/g) and chine (0.383 µg/g, fresh weight) of pork and the lowest in lamb (0.028 µg/g, fresh weight) and pork brain (0.033 µg/g, fresh weight). The greater capacity for accumulation of Se in animal viscera, mainly in liver and kidney, has been established by other authors (Beker et al, 1994;Caurant, 1994;Aro et al, 1994).…”

Comparison of Selenium Determination in Liver Samples by Atomic Absorption Spectroscopy and Inductively Coupled Plasma–Mass Spectrometry

“…This method allows minimum matrix interferences because of selective separation of Se from the matrix by generation of volatile covalent hydrides, although all the Se has to be converted to a form that will result in hydride formation. Detection of Se by HG-AAS has been used successfully for samples such as liver and muscle of cattle and chicken, 1,26 human lung tissue, 36 beef offal and fish, 20 a variety of meat products, 69 skin, 19 plants, soil, 26,44 and plasma. 50 New advances in ICP technology that combine the excellent ion source of an ICP with the ion-detection capabilities of MS suggest that ICP-MS can be used for reliable and sensitive detection of trace elements in biological samples.…”
