Aromatic profile of Sagrantino grape and wine was written by Di Stefano, R.;Mattivi, F.;Caburazzi, M.;Bonifazi, L.. And the article was included in Rivista di Viticoltura e di Enologia in 2009.Computed Properties of C11H14O3 This article mentions the following:
Sagrantino grapes and wines were analyzed for extracted glycoconjugated volatile compounds The compounds were extracted with methanol, the free and glycosidic forms were separated on Isolute C18 cartridges, and the glycosidic forms were hydrolyzed enzymically (Pectinase CLX-150). The volatiles were determined by GC-MS with 1-heptanol as internal standard The influence of the vinification process (fermentation, maturation, aging) was evaluated by anal. of the free and glycoconjugated compounds The Sagrantino grapes had significant contents of glycoconjugated terpene compounds, such as trans-geranic acid, 浼?terpineol, furan linalool oxides, linalool, geraniol, nerol, and 2 isomers of 8-hydroxylinalool. The wines showed decreases of linalool levels, while 浼?terpineol, furan linalool oxides, trans-geranic acid, the 2 isomers of 8-hydroxylinalool, geraniol, and nerol were quant. important. Some compounds, including norisoprenoids, were of marginal importance in grapes but became relevant in wines. Hypotheses have been formulated to explain these results. In the experiment, the researchers used many compounds, for example, Ethyl 2-hydroxy-3-phenylpropanoate (cas: 15399-05-0Computed Properties of C11H14O3).
Ethyl 2-hydroxy-3-phenylpropanoate (cas: 15399-05-0) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Computed Properties of C11H14O3
