and the total volatile compounds concentration was 41.8 mg/L.
Moreover, the odor activity values (OAV) of volatile compounds are
also presented in Table 1. To some extent, OAV can reflect the contribution
of each aroma compound to the sample characteristic flavor.
While the threshold values for 18 compounds remained
unknown, 19 compounds with OAV > 1, and 21 compounds with
OAV < 1 are listed in Table 1. Generally, compounds with OAV > 1
contributed to the overall aroma significantly, while the compounds
with OAV < 1 may still affect wine aroma through an additive
effect of the compound with a similar structure or odor
(Francis & Newton, 2005; González Álvarez et al., 2011).
