Sažetak
The aim of this study was to investigate the differences in macro- (Ca, Na, Mg) and microelement (Co, Cr, Cu, Fe, Mn, Mo, Se, Zn) concentrations in processed cow milk samples. Sterilized UHT milk with 2.8% milk fat produced by five different milk producers in Croatia and one milk producer in the European Union (EU) were randomly purchased from large marketplaces in the Croatian capital, Zagreb. Element concentrations were analysed by inductively coupled plasma mass spectrometry (ICP-MS). Mean element concentrations were in the range (mg/kg): Ca 1111–1285, Na 361.1–453.3, Mg 101.2–113.7, Zn 3.85–4.33 ; (µg/kg): Fe 180.7–269.1, Cu 36.2–45.1, Mo 33.3–47.7, Mn 22.9–31.1, Se 14.7–26.4, Cr 1.91–5.24, Co 0.19–0.32. Significant differences in the content of Ca, Cr, Na, Mn, Mo, Se and Zn were determined between milk samples of different producers. There were no significant differences in the concentrations of Cu or Co. Milk of Croatian producers showed significant differences in Mg, Fe, Mo, Mn, Se and Cr levels compared to milk from the EU producer. The highest concentrations of Fe, Cr and Co were found in the EU milk. Given the importance and frequency of use of processed cow's milk as a foodstuff, the measurement of macro- and microelement contents plays an important role in the evaluation of its nutritional value.
