Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 1-(Furan-2-yl)propan-1-one, is researched, Molecular C7H8O2, CAS is 3194-15-8, about Volatile profile of Madeira wines submitted to traditional accelerated ageing.Related Products of 3194-15-8.
The evolution of monovarietal fortified Madeira wines forced-aged by traditional thermal processing (estufagem) were studied in terms of volatiles. SPE extracts were analyzed by GC-MS before and after heating at 45°C for 3 mo (standard) and at 70°C for 1 mo (overheating). One hundred and ninety volatile compounds were identified, 53 of which were only encountered in baked wines. Most chem. families increased after standard heating, especially furans and esters, up to 61 and 3-fold, resp. On the contrary, alcs., acetates and fatty acids decreased after heating. Varietal aromas, such as Malvasia’s monoterpenic alcs. were not detected after baking. The accelerated aging favored the development of some volatiles previously reported as typical aromas of finest Madeira wines, particularly phenylacetaldeyde, β-damascenone and 5-ethoxymethylfurfural. Addnl., Et butyrate, Et 2-methylbutyrate, Et caproate, Et isovalerate, guaiacol, 5-hydroxymethylfurfural and γ-decalactone were also found as potential contributors to the global aroma of baked wines.
