| berry density and size as factors related to the physicochemical characteristics of muscat hamburg table grapes (vitis vinifera l.). | the aim of this work was to determine the impact of using independently berry density and diameter as sorting methodologies on important physicochemical parameters affecting the grape quality, such as mechanical properties, phenolic composition and aromatic profile. muscat hamburg berries were classified according to the density by flotation in different salt solutions and to the diameter. the three most representative density (1081, 1088 and 1094 kg/m(3)) and diameter (16-17, 18-19 and 20-21 mm ... | 2015 | 25466001 |
| chemical composition, bioactive compounds, and volatiles of six table grape varieties (vitis vinifera l.). | six table grape cultivars (centennial seedless, chasselas, italia, italia rubi, alphonse lavallée, and muscat de hambourg) were analyzed for their levels of soluble solids, titratable acidity, sugars, organic acids, vitamin c and e, carotenoids, polyphenolics and volatile compounds during two successive years. descriptive sensory analyses of the six table grape varieties were also performed. mainly due to anthocyanins, black cultivars had the highest total phenolic contents. alphonse lavallée ha ... | 2018 | 28946307 |
