A mixture containing 14 ethyl esters at concentrations found in wine (V1) was prepared and kept as reference. Isointense and qualitatively similar aroma vectors with a reduced number of esters (V2-V7) were prepared. Those vectors were introduced in two reconstituted wines to assess whether simpler vectors could replace V1 without compromising wine quality. In the simpler young wine model, V1 could be replaced by a vector containing just 3 odorants (ethyl 2-methylbutyrate, ethyl butyrate and hexanoate). In the oaky model, a vector containing just ethyl 2-methylbutyrate (V7) could replace V1 without any discernible sensory change. Results also reveal that sub- or perithreshold odorants play outstanding roles on the overall odour intensity of the mixture and that aroma simplification concomitantly implies an increase in the amount of odorant required to keep the intensity of the aroma vector. info:eu-repo/grantAgreement/ES/DGA/T53 info:eu-repo/grantAgreement/ES/MINECO/AGL2014-59840 info:eu-repo/grantAgreement/ES/MINECO/AGL2017-87373-C3-1-R info:eu-repo/grantAgreement/ES/MINECO/IJCI-2015-23444 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 7.514 2020 CHEMISTRY, APPLIED 7 / 74 = 0.095 2020 Q1 T1 NUTRITION & DIETETICS 6 / 88 = 0.068 2020 Q1 T1 FOOD SCIENCE & TECHNOLOGY 7 / 144 = 0.049 2020 Q1 T1 1.772 2020 Analytical Chemistry 2020 Q1 Medicine (miscellaneous) 2020 Q1 Food Science 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Sáenz-Navajas, Maria-Pilar Universidad de Zaragoza (orcid)0000-0001-7225-2272 Valentin, Dominique Universidad de Zaragoza (orcid)0000-0002-4353-2483 Ferreira, Vicente 2009 750 Universidad de Zaragoza Dpto.
