Characterization of the key aroma compounds in a commercial Amontillado sherry wine by means of the sensomics approach.
J Agric Food Chem. 2015 May 20; 63(19):4761-70.JA

Abstract

An aroma extract dilution analysis (AEDA) carried out on the volatile fraction isolated by extraction/solvent-assisted flavor evaporation (SAFE) distillation from a commercial Amontillado sherry wine revealed 37 odor-active compounds with flavor dilution (FD) factors in the range of 16-4096. Among them, 2-phenylethanol (flowery, honey-like) and ethyl methylpropanoate (fruity) showed the highest FD factors, followed by ethyl (2S,3S)-2-hydroxy-3-methylpentanoate (fruity) reported for the first time in sherry wine. A total of 36 aroma-active compounds located by AEDA were then quantitated by a stable isotope dilution assay, and their odor activity values (OAVs; ratio of concentration to odor threshold) were calculated. The highest OAV was displayed by 1,1-diethoxyethane (2475; fruity), followed by 2- and 3-methylbutanals (574; malty) and methylpropanal (369; malty). Aroma reconstitution experiments and a comparative aroma profile analysis revealed that the entire orthonasal aroma profile of the Amontillado sherry wine could be closely mimicked.
