Estimation of copper intake in moderate wine consumers in Croatia

Abstract

To estimate Cu exposure level from wine consumption and to assess possible health risk for moderate wine consumers, wine samples were collected from different wine-growing areas of Croatia. Median concentrations were 180 μg L -1, range (76 to 292) μg L -1, in commercial wines and 258 μg L -1, range (115 to 7600) μg L -1, in homemade wines (P>0.05). Maximum permitted level of 1000 μg L -1 was exceeded in three homemade wines. However, daily intake of Cu from wine (in the range from 0.02 mg d -1 to 1.52 mg d -1) estimated from Cu concentration in all wine samples is lower than the tolerable upper intake level of 5 mg d -1 proposed by the EU Scientific Committee on Food and does not present a risk to moderate wine consumers.
