Effect of Cultivar and Geographical Origin on the Volatile Composition of Greek Monovarietal Extra Virgin Olive Oils
نویسندگان
چکیده
Extra virgin olive oil (EVOO) is highly appreciated by consumers for its unique sensory characteristics that are directly related to volatile composition. The objective of this study was investigate the effect cultivar and geographical origin on composition Greek monovarietal EVOOs. Samples three local cultivars (Koroneiki, Kolovi Adramytini) originating from areas Greece (Crete, Lesvos Peloponnese), spanning two consecutive harvesting periods, were selected. Their components determined using headspace solid-phase microextraction combined with gas chromatography–mass spectrometry. More than 70 compounds identified. Alcohols dominant class (43–50%), followed ketones (12–24%), esters (12–18%) aldehydes (4–12%). most prominent (Z)-3-hexen-1-ol (6–11%), 1-penten-3-ol (7–11%), (E)-3-hexenyl acetate (0.5–11%) 3-pentanone (8–16%). Significant differences observed highlighted. Clear separations between samples different geographic provenances achieved multivariate analysis discriminating volatiles Additionally, receiver operating characteristic (ROC) curve analysis, a combination five chemical markers found superior (area under curve, AUC: 1.00; predictive accuracy: 100%) correct classification Koroneiki EVOOs according origin.

Two hundred twenty-one extra virgin olive oils (EVOO) were extracted from four olive mono-cultivars (Koroneiki, Tsounati, Adramitini, and Throubolia) originated from four divisions of Greece (Peloponnesus, Crete, Zakynthos, and Lesvos) and collected in five harvesting periods (2002-2006 and 2007-2008). All samples were chemically analysed by means of (1)H and (31)P NMR spectroscopy and characte...

متن کاملAntioxidants in Greek Virgin Olive Oils
Greece is ranked third after Spain and Italy in virgin olive oil production. The number of Greek olive cultivars-excluding clonal selections-is greater than 40; however, more than 90% of the acreage is cultivated with 20 cultivars, adapted to a wide range of environmental conditions. Greek virgin olive oils, produced mainly with traditional, non-intensive cultivation practices, are mostly of ex...
متن کاملEffect of Fatty Acid Composition on Thermal Stability of Extra Virgin Olive Oil
Background: Fatty acids are the main compounds in edible oils. Oil thermal stability depends on the composition of fatty acids. So, this study was conducted to investigate the effect of fatty acid composition on the oxidative stability of extra virgin olive oil during heating process. Methods: Totally, eight virgin olive oil samples, including five imported oils from market place of Ma...
