摘要：In this study, oil samples of Ayvalik and Memecik, domestic olive cultivars of Aegean region providing aproximately 65 % of virgin olive oil production of Turkey, were analysed and classified by using common spectroscopic (FTNIR, FTIR-ATR, Excitation-Emission [EX-EM] Fluorescence Spectroscopy and Synchronous [SYN] Fluorescence Spectroscopy) methods. The analysed oil samples consisted of totally 9 samples – except 1 mixed organic oil sample – taken from North Aegean [ Ayvalık olive cultivar] (n=4) and South Aegean [Memecik olive cultivar] (n=4) subzones. The samples were stored in PET glass at room temperature and they were divide into two groups including exposed to diffused day ligth and covered with aluminium folios [dark]. The classification of Ayvalık ve Memecik olive oil samples were carried out by the most used chemometric (Principal Component Analysis, PCA and Hierarchical Cluster Analysis, HCA) techniques. Ayvalık and Memecik oil samples were classified noticeable according to cultivars, origin district or processing applications (exposed to ligth or dark and store conditions) based on the results of spectroscopic methods. In additon, the spectroscopic methods could be exhibited promising effects for the correct classification – also, information on possible store conditions and adulterations – of virgin olive oil was seen.
