The behavior of two esters (ethyl hexanoate, ethyl decanoate) was studied in a control wine or in the same wine supplemented with the GSE in preconsumption (in vitro headspace-stir bar sorptive extraction-gas chromatography mass spectrometry (HS-SBSE-GC/MS) and orthonasal perception) and consumption (intraoral-HS-SBSE-GC/MS and dynamic retronasal perception) conditions. For the compound ethyl hexanoate, no significant differences (<i>p</i> > 0.05) among wines were observed in the in vitro analyses while they were observed in the three in vivo experiments (<i>p</i> < 0.05). Thus, the wine supplemented with the GSE showed lower (35%) in vivo release and ortho (36%) and retronasal (16%) perception scores than the control wine. Overall, this suggests that components of the GSE could interact with this compound, directly and/or through complexes with oral components, affecting its release and conditioning its perception. However, perceptual interactions and effects of polyphenols on oral esterases cannot be discarded. On the contrary, the compound ethyl decanoate was not significantly affected by the addition of GSE. In conclusion, the addition of tannin extracts to wines can modulate aroma perception in a compound-dependent manner. | Descripción: | This article belongs to the Special Issue Novel Analysis on Aroma Compounds of Wine, Vinegar and Derived Products. | Versión del editor: | https://doi.org/10.3390/foods10010093 | URI: | http://hdl.handle.net/10261/227865 | DOI: | 10.3390/foods10010093 | E-ISSN: | 2304-8158 | Identificadores: | doi: 10.3390/foods10010093 |
