| Popis: | The evolution of pre-fermentative volatiles and of the global aroma potential in three Italian neutral varieties (‘Nebbiolo,’ ‘Barbera’ and ‘Dolcetto’) was assessed from veraison to harvest by SBSE–GC/MS. C6 and C9 compounds, benzene derivatives, bound monoterpenes and sesquiterpenes showed differences among varieties in quantity and profiles during berry ripening. Quantitatively, the most of total monoterpenes, C-13 norisoprenoids and sesquiterpenes were detected after acid hydrolysis. Among pre-fermentative norisoprenoids, exclusively β-ionone was detected with different kinetics among varieties. Monoterpene accumulation started around veraison with the exception of (E)-geranylacetone, whose content was already high at veraison. (E)-Geranylacetone, deriving from the degradation of carotenoids, could become a target molecule to study indirectly the accumulation of carotenoids. Data allowed to measure the global aroma potential and the pre-fermentative volatiles of grapes: result interpretation suggested a number of implications on biosynthetic processes that have been addressed. |
