Forty-nine virgin olive oil samples (VOOs) from six different locations of the western part of Turkey (Izmir, Manisa, Aydin, Mugla, Bursa and Edremit Bay) were analysed with ICP-MS and EA-IRMS. V, Mn, Ni, Cu, Ba, Na, K, Ca, Fe, Mg, Pb, As, Co, Cr and Zn were found in the olive oil samples and determined delta C-13 stable istope ratios. Data from the olive oil samples were compiled and classified with chemometric approach. The results showed that there is significant potential to successfully authenticate olive oils according to Fe and Zn on the Manisa and delta C-13 have dominant effect on the location of Edremit Bay. As a result, the outcome of this study could be used to identify the geographical origin of olive oils especially for the Manisa and Edremit Bay locations.en10.1007/s00217-017-2876-4info:eu-repo/semantics/closedAccessAuthenticationGeographical originTrace elementsStable isotope carbon ratioPrincipal component analysisHierarchical cluster analysisArticle2431017191727WOS:000410810100004Q2Q2
