It is well known that the VOO volatile fraction depends strongly on different aspects, which encompass genetic, agronomic, processing, and post\u2010processing factors. In this research, we developed a method for the qualitative and semiquantitative determination of volatile components in VOOs subjected to thermal stress by headspace extraction online coupled to gas chromatography\u2013mass spectrometry (HS\u2013GC\u2013MS).<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>The method was applied to 100 extra\u2010virgin olive oil (EVOO) samples, which led to the tentative identification of 52 volatile components, including 12 alcohols, 17 aldehydes, three ketones, one ether, two furans, two carboxylic acids, and 15 hydrocarbons. The method was used to study the cultivar effect and the main biochemical pathways involved in the synthesis of volatile compounds, with special emphasis on those formed by degradation of unsaturated fatty acids (FAs). Principal component analysis (PCA), explaining 76.7% of the total variability, showed that the volatile profile of EVOOs subjected to thermal stress allowed discriminating samples from different cultivars.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>Volatiles detected in EVOOs subjected to thermal stress with the highest contribution to discrimination between the selected cultivars were correlated with the concentration of the three main FAs in VOO, namely oleic, linoleic, and linolenic acids. The FA profile seems to be especially relevant to explain the concentration of certain volatile compounds with direct incidence on the organoleptic properties. \u00a9 2021 Society of Chemical Industry<\/jats:p><\/jats:sec>","DOI":"10.1002\/jsfa.11129","type":"journal-article","created":{"date-parts":[[2021,1,27]],"date-time":"2021-01-27T09:27:14Z","timestamp":1611739634000},"page":"4829-4837","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Influence of the fatty acid profile on the volatile components of virgin olive oil subjected to thermal stress"],"prefix":"10.1002","volume":"101","author":[{"given":"Sonia","family":"Tom\u00e9\u2010Rodr\u00edguez","sequence":"first","affiliation":[{"name":"Maim\u00f3nides Institute for Biomedical Research (IMIBIC) Reina Sof\u00eda University Hospital  C\u00f3rdoba Spain"},{"name":"Department of Analytical Chemistry University of C\u00f3rdoba  C\u00f3rdoba Spain"},{"name":"Nanochemistry University Institute (IUNAN), Campus of Rabanales University of C\u00f3rdoba  C\u00f3rdoba Spain"},{"name":"CIBER Fragilidad y Envejecimiento Saludable (CIBERFES) Carlos III Health Institute  Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4658-8212","authenticated-orcid":false,"given":"Carlos A","family":"Ledesma\u2010Escobar","sequence":"additional","affiliation":[{"name":"Maim\u00f3nides Institute for Biomedical Research (IMIBIC) Reina Sof\u00eda University Hospital  C\u00f3rdoba Spain"},{"name":"Department of Analytical Chemistry University of C\u00f3rdoba  C\u00f3rdoba Spain"},{"name":"Nanochemistry University Institute (IUNAN), Campus of Rabanales University of C\u00f3rdoba  C\u00f3rdoba Spain"},{"name":"CIBER Fragilidad y Envejecimiento Saludable (CIBERFES) Carlos III Health Institute  Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 M","family":"Penco\u2010Valenzuela","sequence":"additional","affiliation":[{"name":"Spanish Association of Olive Producing Municipalities (AEMO), Campus Alameda del Obispo  C\u00f3rdoba Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0697-719X","authenticated-orcid":false,"given":"Feliciano","family":"Priego\u2010Capote","sequence":"additional","affiliation":[{"name":"Maim\u00f3nides Institute for Biomedical Research (IMIBIC) Reina Sof\u00eda University Hospital  C\u00f3rdoba Spain"},{"name":"Department of Analytical Chemistry University of C\u00f3rdoba  C\u00f3rdoba Spain"},{"name":"Nanochemistry University Institute (IUNAN), Campus of Rabanales University of C\u00f3rdoba  C\u00f3rdoba Spain"},{"name":"CIBER Fragilidad y Envejecimiento Saludable (CIBERFES) Carlos III Health Institute  Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,2,15]]},"reference":[{"key":"e_1_2_5_2_1","first-page":"29","article-title":"Amending regulation (EEC) No 2568\/91 on the characteristics of olive oil and olive\u2010residue oil and on the relevant methods of analysis","volume":"266","author":"Comission Delegated Regulation (EU)","year":"2015","journal-title":"Off J Eur Union"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/biof.1318"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.2174\/138161211795428885"},{"key":"e_1_2_5_5_1","unstructured":"IOC International Olive Council.Sensory analysis of olive oil: method for the organoleptic assessment of virgin olive oil COI\/T.20\/Doc.
