Analyses of metal concentrations in Croatian wines using IC and ICP-OES
Ion chromatography (IC) and inductively coupled plasma optical emission spectrometry (ICP-OES) were used to analyze concentrations of nine metals in three northwestern Croatian wines. Two Pinot grey wines from different wine regions (denominated as A and B) were produced in 2009. Blackberry wine (denominated as C) was produced in 2007. IC was used to analyze concentrations of sodium, potassium, magnesium and calcium. Levels of potassium and magnesium were significantly higher in blackberry wine. The most pronounced difference in all samples was detected for calcium, which was 17.6-23.6 times higher in blackberry wine. Concentrations of copper, iron, manganese, zinc, nickel and chromium were analyzed using ICP-OES. Concentrations of sodium and copper were almost similar in all three wines. The significant differences among wines were detected for iron and manganese. Concentration of iron in blackberry wine was five times lower, while manganese was 3.62-5.38 times higher, compared with Pinot grey wines. The highest level of zinc was found in Pinot grey wine denominated as A. Value of nickel in blackberry wine was up to nine times higher than in Pinot grey wines. According to the obtained data, levels of calcium, nickel, iron and manganese differed in all tested wines, while chromium was not detected.
