Content of Essential and Toxic Elements in Fruit of Raspberry Cultivar ‘Meeker’

Abstract

Raspberries are one of the most important export products from Serbia. In order to evaluate the fruit quality of raspberry cultivar ‘Meeker’, in this study, contents of essential and toxic elements were analysed by means of inductively coupled plasma–optical emission spectrometry (ICP–OES) The most abundant essential elements in the fruit were K, Ca and Mg (2019.86, 310.28 and 275.37 mg kg-1, respectively). To assess the safety of dietary intake of elements through the consumption of ‘Meeker’ fruits, the estimated weekly intake (EWI) for Al, Cu, Mn, Ni, Pb and Zn was calculated and compared with the provisional tolerable weekly intake (PTWI). EWI for Ni (0.033) was on the upper limit value.

Maline su jedan od najvažnijih izvoznih proizvoda iz Srbije. U ovom radu analiziran je sadržaj esencijalnih i toksičnih elemenata primenom induktivno spregnute plazme sa optičkom emisionom spektrometrijom (eng. ICP-OES), kako bi se procenio kvalitet plodova maline sorte Meeker. Najzastupljeniji esencijalni elementi u plodu bili su K, Ca i Mg (2019,86, 310,28 i 275,37 mg kg-1, respektivno). Da bi se procenila dijetetska bezbednost unosa elemenata konzumiranjem maline Meeker, procenjen je nedeljni unos (PNU) za Al, Cu, Mn, Ni, Pb i Zn i upoređen je sa tolerantnim nedeljnim unosom (TNU). Procenjeni nedeljni unos (PNU) za Ni (0,033) bio je na gornjoj graničnoj vrednosti.
