EVALUATION OF THE CONTENTS OF COOPER, IRON DHE ZINC IN SELECTED WINES FROM WESTERN PART – KOSOVO

Abstract

Wine consumption delivers macro elements and microelements necessary for the proper metabolism, to perform different functions in the body. The concentrations of Cu, Fe and Zn were determined in nine brands of Kosovo white and red wines by flame atomic absorption spectrometer (FAAS) after digesting the wine samples with 0.1M HNO₃.

The Cu concentrations varied from 0.01 to 0.45 mg/L in wines, and the Fe concentrations fluctuated from 1.12 to 8.90 mg/L, while the Zn levels were in the range from 0.11 to 0.44 mg/L. The contents of Cu, Fe and Zn showed that Kosovo brands wines could serve as good dietary sources of the essential microelements, and the determined values were within the allowed metals levels in wines for human consumption.
