Effect of fermentation temperature on volatile compounds of Petit Verdot red wines from the Spanish region of La Mancha (central-southeastern Spain) was written by Izquierdo-Canas, P. M.;Gonzalez Vinas, M. A.;Mena-Morales, A.;Perez Navarro, J.;Garcia-Romero, E.;Marchante-Cuevas, L.;Gomez-Alonso, S.;Sanchez-Palomo, E.. And the article was included in European Food Research and Technology in 2020.Application of 695-06-7 This article mentions the following:
The aim of this work was to research the relationship between volatile composition of Petit Verdot red wines and the fermentation temperature Winemaking process was carried out at 17鎺矯, 21鎺矯, and 25鎺矯 temperatures Solid-phase extraction (SPE) and gas chromatog.-mass spectrometry (GC-MS) were used to analyze volatile compounds The odor activity values (OAVs) from the different compounds were classified into seven odorant series that describe the aroma profile (fruity, floral, green/fresh, sweet, spicy, fatty, and other odours). The value of each aromatic series was obtained by adding the OAVs of the volatile compounds to each series. The volatile composition was significantly affected by the temperature of the fermentation In general, the increase in the fermentation temperature of La Mancha Petit Verdot red wines from 17 to 25鎺矯 produced an increase in the concentration of volatile aroma compounds The highest aroma contributions to Petit Verdot wine were fruity, sweet and floral series, followed by fatty and spicy series, regardless of fermentation temperature The highest values of aromatic series were found in wines fermented at 21鎺矯. The results of this work show that changes in the fermentation temperature of wines can have a significant impact on their volatile compound profile. In the experiment, the researchers used many compounds, for example, 5-Ethyldihydrofuran-2(3H)-one (cas: 695-06-7Application of 695-06-7).
5-Ethyldihydrofuran-2(3H)-one (cas: 695-06-7) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Application of 695-06-7
