Sažetak
The objective of this preliminary study is to demonstrate that the combination of multi-element analysis, several isotopic ratios (13C/12C, 15N/14N, 18O/16O, 2H/1H) and selected chemical and physical parameters (fruit mass, antioxidant activity, content of ascorbic acid and total phenols) can be used to differentiate the varieties of Slovenian apples, the geographical location of their growth and agricultural practice. The stable isotope parameters in sugar, pulp, protein and water were shown to be the most significant variables in this regard. Botanical origin (cultivar) was found to have a major influence on the δ13C and δ15N values of proteins and the δ18O and δD values of water. Geographical regions were well separated based on the δ18O and δD values in water and the concentrations of Rb and S in fruit juice. The most significant variables to distinguish between organically and conventionally cultivated fruits were found to be 15N/14N ratio and antioxidant activity. In addition, significant differences were also observed in ascorbic acid content.
