Assessment of total phenolic compounds, condensed tannins, anthocyanins, and carotenoids in samples of Syrah grapes, grape pomace, and lees.
| Analysis | Grape | Grape Pomace | Lees |
|---|---|---|---|
|
Total phenolic compounds (mg GAE/100 g sample) |
350.3 ± 8.3 | 895.5 ± 15.8 * | 102.43 ± 6.1 |
|
Condensed tannins (mg epicatechin/100 g sample) |
1098.3 ± 48.1 | 2211.6 ± 207.3 * | 295.60 ± 29.1 *,† |
|
Total monomeric anthocyanins (mg M-3-glc/100 g sample) |
20.84 ± 0.15 | 25.68 ± 1.6 * | 13.47 ± 0.36 *,† |
|
Total carotenoids (μg β-carotene/g sample) |
747.33 ± 12.7 | 782.45 ± 55 | 616.30 ± 21.3 *,† |
Values are presented as means ± SD (n = 3). Statistical comparisons were conducted using one-way analysis of variance (ANOVA), followed by Tukey’s post hoc test. * p < 0.05 vs. grapes; † p < 0.05 vs. grape pomace. Abbreviations: GAE, galic acid; M-3-glc, Myricetin-3-glucoside.
