• Brillante, Luca; De Rosso, Mirko; Dalla Vedova, Antonio; Maoz, Itay; Flamini, Riccardo; Tomasi, Diego 2018-03-01 Grape withering is a process used to produce reinforced wines and raisins. Dehydration is usually carried out postharvest by keeping ripe grapes in special warehouses in controlled conditions of temperature, relative humidity (RH) and air flow. Alternatively, grape clusters can be left on the vines after the canes have been pruned. In general, dehydration increases stilbenes in grape, but there are few studies on the effects of on- vine withering. The stilbene profiles of Raboso Piave grape during postharvest and on- vine dehydration were studied here.
High-resolution mass spectrometry (MS) was used to identify 19 stilbenes, including resveratrol monomers, dimers (viniferins), oligomers and glucoside derivatives. The two dehydration methods generally had different effects on the above nutraceuticals in grape. The samples kept in warehouses revealed significant increases in Z-ω-viniferin, E-ϵ-viniferin, δ-viniferin and another resveratrol dimer which were not observed in the plants.
Trans-Resveratrol increased significantly only in samples dehydrated in the warehouse at 21 °C and 60-70% RH. The findings increase knowledge of stilbene composition in grapes subjected to withering on- vine. The choice of dehydration method affects the contents of these nutraceuticals in the grape and consequently in wines. Reasonably, it could also affect other secondary metabolites important for wine quality. © 2017 Society of Chemical Industry.

These measurements were performed by isotope ratio monitoring by mass spectrometry coupled to an elemental analyzer (irm-EA/MS. Then a series of wines produced by vines of which water status was assessed during the growing season with predawn leaf water potential measurements, was studied by irm-EA/MS. As expected δ13C is correlated to vine water status conditions, as a result of stomatal closure. The ethanol of these specific wines was also analyzed by isotope ratio monitoring and by nuclear magnetic resonance (irm-13C NMR to determine carbon-13 composition on the two specific sites of the ethanol skeleton.
If these measurements confirm the correlation between 13C composition and vine growth conditions, the 13C stereospecific information does not make vine water status assessment more precise. • Zhang, Guoyu; Ren, Yi; Sun, Honghe; Guo, Shaogui; Zhang, Fan; Zhang, Jie; Zhang, Haiying; Jia, Zhangcai; Fei, Zhangjun; Xu, Yong; Li, Haizhen 2015-12-24 Pumpkin (Cucurbita maxima Duch.) is an economically important crop belonging to the Cucurbitaceae family. However, very few genomic and genetic resources are available for this species. Polnaya tablica znachenij sinusov kosinusov tangensov kotangensov.
