Contribution of specific volatile markers to green and ripe fruity attributes in extra virgin olive oils studied with three analytical methods. Food Chemistry, 399. https://doi.org/10.1016/j.foodchem.2022.133942.0308-81461873-7072https://hdl.handle.net/11441/145627An objective sensory evaluation of extra virgin olive oil (EVOO), involving the chemical characterization of positive attributes, is of interest. These attributes are objectively divided, according to fruitiness, into “green” and “ripe” fruity. This work studied the differentiation in the volatile profile of EVOOs into these two classes, obtained by three analytical methods, including different extraction techniques and detectors and two data processing strategies, and their relation with sensory results. According to the results, each method allowed the characterization of the two classes, providing information on different volatile compounds, which increased in number through PARADISe software (14 more than the conventional processing). Moreover, some volatile compounds showed significant differences between the two classes, 16 highlighted by the variables with importance in projection (VIP) for green fruity (e.g. (Z)-3-hexen-1-ol, methyl ether) and 23 for ripe fruity EVOOs (e.g. (Z)-2-hexen-1-ol), which could be considered as useful markers to complement quality assessment.application/pdf13 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Extraction methodsGas-chromatographyGreen fruityRipe fruityVirgin olive oilVolatile profileinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1016/j.foodchem.2022.133942
