Forty seven monovarietal olive oils were collected from four Western Greek islands during the 2007-2008 harvesting period. Samples were subjected to physicochemical parameter analysis including determination of acidity, peroxide value, K232, K270, Ξ”K indices, chlorophyll and carotenoid content, trace elements, fatty acids and Ξ΄18O and Ξ΄13C isotope ratios in an effort to classify olive oil samples according to geographical origin. Chemometric analysis including MANOVA and Linear Discriminant Analysis (LDA) showed that when all above (14 different physicochemical parameters) were combined, a correct classification rate of 94.5% and 82.6% was achieved using the original and cross validation method respectively.
