Sažetak
Chemical composition of the wine is a complex solution of various elements, organic and inorganic compounds and their complexes. It depends on many factors such as: region of production, winemaking practice, grape variety, soil, air, yeasts and procedures in the production of wine. Wine is complex medium in which macro and microelements have very important place, for positive but also potentially negative effects. Consumption of wine on a daily basis contributes to the needs of the human body for essential elements such as calcium, chromium, potassium, zinc. Aluminum, copper, iron, manganese, zinc depending on the concentration can have a detrimental effect on the stability of the wine and its commercial value, while cadmium, lead and bromine are potentially toxic. The aim was to determine macro-and microelements in „Graševina“ wine from different winegrowing sub-regions and zones of production for the purpose of linking macro and microelements to the geographical origin of wine. Inductively coupled plasma optical emission spectrometry (ICP–OES) technique was used. In the samples were determined values for macro and microelements. Based on the results the wine „Graševina“ from production zone CI have higher content of macro and microelements compared to wines from production zone B.
