| Abstract: | This study examined the applicability of stable isotope and multi-element data for determining the geographical
origin of fresh apple juices. Samples included three apple cultivars (Idared, Golden Delicious
and Topaz) harvested in 2011 and 2012 from five different geographical regions of Slovenia. Regional discrimination
of the juice samples was most successful when using linear discriminant analysis (LDA) and
taking into account the following parameters: d2H and d18O content of juice water; d15N and d13C content
of the pulp, (D/H)I and (D/H)II in ethanol and the concentration of S, Cl, Fe, Cu, Zn and Sr. Overall prediction
ability was 83.9%. The factors that best distinguished the different types of cultivar were the d2H and
d18O content of fruit juice water; the d13C and (D/H)I content of ethanol; and the concentration of S, Mg, K,
Cu, and Ti. Prediction ability, taking into account all ten parameters, was 75.8%. |
