Formulations of Rancid and Winey-Vinegary Artificial Olfactory Reference Materials (AORMs) for Virgin Olive Oil Sensory Evaluation [Dataset]; DIGITAL.CSIC; http://dx.doi.org/10.20350/digitalCSIC/13703 | Resumen: | This data set contains the underlying data of the scientific publication: Aparicio-Ruiz R., Barbieri S., Gallina Toschi T., García-González D.L. (2020). Formulations of Rancid and Winey-Vinegary Artificial Olfactory Reference Materials (AORMs) for Virgin Olive Oil Sensory Evaluation. Foods, 9 (12), 1870, https://doi.org/10.3390/foods9121870. Panel test is the only sensory method included in international regulations of virgin olive oils and its application is compulsory. At present, there is no reference material (RM), in the strict sense of the term, to be used as a validated standard for sensory defects of virgin olive oil with which tasters can be trained. Usually, real samples of virgin olive oils assessed by many panels for the International Olive Council (IOC) ring tests are used as materials of reference in panel training and control. These data correspond to the work carried out to formulate RM that emulate rancid and winey-vinegary defects found in virgin olive oils with the aim of providing reproducible RMs that can be prepared on demand. Under the criteria of representativeness, verified with the advice of the IOC, aroma persistence, and simplicity in formulation, two RMs for winey-vinegary and rancid were obtained by diluting acetic acid and ethanol (winey-vinegary defect) and hexanal (rancid defect) together with other compounds that are used to modify aroma and avoid non-natural sensory notes. | Descripción: | Content of the file OLEUM_Portable_ReferenceMaterials_VOO.xlsx/.ods: • Volatile markers: this sheet contains data of volatile markers of the virgin olive oils sensory defects winey-vinegary and rancid, sensory characteristics and corresponding odor threshold relating to an oil matrix. • Relative areas: this sheet contains data of relative areas of volatile compounds selected to emulate winey-vinegary and rancid defects in VOOs in a set of 60 samples and in RMs provided by the International Olive Council for each of the defects (RM IOC). • Formulations RM AV: this sheet contains data of the main formulations (volatile compounds and concentrations in mg/kg) emulating winey-vinegary aroma in virgin olive oil and evaluation by assessors in terms of suitability as possible RM. • Formulation RM R: this sheet contains the data of the main formulations (volatile compounds and concentrations in mg/kg) emulating rancid aroma in virgin olive oil and evaluation by assessors about their eligibility as possible RM. | URI: | http://hdl.handle.net/10261/227413 | DOI: | 10.20350/digitalCSIC/13703 | Referencias: | Aparicio-Ruiz, R. ; Barbieri, Sara; Gallina Toschi, Tullia; García-González, Diego L.
