CT, SO2 addition wine; HTB, synthetic hydroxytyrosol addition wine; HTG, hytolive addition wine. Analyses of variance, levels of significance (LS): *p < 0.05, **p < 0.01,
p < 0.001.
In bold odorants with maximum differences on olfactometric scores.
aIdentification based on coincidence of gas chromatography retention on capillary columns and mass spectrometric data with those of pure compounds available in the
laboratory or with NIST mass spectrometric library data.
bIdentification based on coincidence of chromatographic retention data on DB-WAX and DB-5 capillary columns and on the similarity of odor previously reported. n.i, not
identified compound; MF, modified frequency; DMF (%), differences in modified frequency between HT and CT wines.
1Linear retention index calculated on DB-WAX and DB-5capillary columns.
