The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 1-(Furan-2-yl)propan-1-one( cas:3194-15-8 ) is researched.Category: benzoxazole.Paravisini, Laurianne; Prot, Aurelie; Gouttefangeas, Cecile; Moretton, Cedric; Nigay, Henri; Dacremont, Catherine; Guichard, Elisabeth published the article 《Characterisation of the volatile fraction of aromatic caramel using heart-cutting multidimensional gas chromatography》 about this compound( cas:3194-15-8 ) in Food Chemistry. Keywords: caramel cooking aroma volatile furan lactone acid; Caramel; Heart-cutting multidimensional gas chromatography (MDGC); Mass Spectrometry; Odorant compounds; Olfactometry. Let’s learn more about this compound (cas:3194-15-8).
The first aim of the study was to improve characterization of the volatile fraction of aromatic caramel by applying heart-cutting multidimensional gas chromatog. coupled to mass spectrometry and olfactometry (MDGC-MS-O) on targeted odorant fractions. The second aim was to compare the volatile composition of two caramel samples, which differed in terms of their carbohydrate composition and cooking process. MDGC analyses enabled identification of 37 compounds (17 with the addition of pure standard) in the burnt sugar caramel, 20 of which were reported for the first time in caramel. Fifteen compounds were identified as odor-active and described using a range of attributes such as floral, roasted, spicy and almond. Furans, lactones and acids resulting from the thermal breakdown of sugars predominated in the volatile fraction of the burnt sugar caramel, due to the harsher cooking conditions. These results have enabled a clearer understanding of aromatic caramel as well as the identification of new compounds which might make an important contribution to its aroma.
