Volatile profile of Madeira wines submitted to traditional accelerated ageing was written by Pereira, Vanda;Cacho, Juan;Marques, Jose C.. And the article was included in Food Chemistry in 2014.Recommanded Product: Ethyl 3-ethoxypropanoate The following contents are mentioned in the article:
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. This study involved multiple reactions and reactants, such as Ethyl 3-ethoxypropanoate (cas: 763-69-9Recommanded Product: Ethyl 3-ethoxypropanoate).
Ethyl 3-ethoxypropanoate (cas: 763-69-9) 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. 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: Ethyl 3-ethoxypropanoate
