Sažetak
Strawberries (Fragaria × ananassa) are fruits which represent a good source of ascorbic acid, anthocyanins and flavonols and which have a high antioxidant activity. Thus they are a useful contributor to healthy nutrition. However not the organic components are of great importance, but also the trace and ultratrace elements contained in the berries. On the one hand the concentrations of toxic elements have to be controlled, on the other hand the amount of essential elements is of interest. In this research work strawberries grown in Croatia and in Austria were analyzed for their trace elemental content. After a microwave assisted digestion procedure the concentrations of 27 elements, namely Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Mo, Na, Ni, Pb, Sc, Se, Si, Sm, Sn, Sr, Tl, and Zn were determined by inductively coupled plasma – optical emission spectrometry (ICP-OES). Reference ranges for the elements investigated were established. The results for the strawberries from Croatia were compared to those from Austria in order to see geographical differences.
