Volatile composition of Baga red wine Assessment of the identification of the would-be impact odorants was written by Rocha, Silvia M.;Rodrigues, Fanny;Coutinho, Paula;Delgadillo, Ivonne;Coimbra, Manuel A.. And the article was included in Analytica Chimica Acta in 2004.Recommanded Product: 15399-05-0 This article mentions the following:
Wines produced from Baga native variety from the Portuguese Bairrada Appellation, harvest 2000, were submitted to a liquid-liquid continuous extraction with dichloromethane and anal. by gas chromatog.-mass spectrometry (GC-MS). A total of 53 compounds were identified and quantified. This wine has 225 mg l-1 volatile compounds, which include aliphatic and aromatic alcs. (44%), acids (27%), esters (15%), lactones (6%), amides (5%), and phenols (1%). To achieve the identification of the major would-be impact odorants, the aroma index was calculated using the concentration of each volatile component and the corresponding odor threshold reported in the literature. This methodol. proved suitable, as a preliminary step, for the determination of the would-be impact odorants of Baga wine. From the 53 compounds identified, 9 were determined as the most powerful odorants: guaiacol, 3-methylbutanoic acid, 4-ethoxycarbonyl-γ-butyrolactone, isobutyric acid, 2-phenylethanol, γ-nonalactone, octanoic acid, Et octanoate and 4-(1-hydroxyethyl)-γ-butyrolactone. These data suggest Baga wine as a fruity-type product with an aroma correlated to a restricted number of compounds In the experiment, the researchers used many compounds, for example, Ethyl 2-hydroxy-3-phenylpropanoate (cas: 15399-05-0Recommanded Product: 15399-05-0).
Ethyl 2-hydroxy-3-phenylpropanoate (cas: 15399-05-0) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Recommanded Product: 15399-05-0
