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°C, 21°C, and 25°C 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°C 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°C. The results of this work show that changes in the fermentation temperature of wines can have a significant impact on their volatile compound profile. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Recommanded Product: 2380-78-1).
4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. 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. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Recommanded Product: 2380-78-1
