Xinjiang is the main production area of figs in China. In this work, three different methods (SDE, SAFE, and SPME) were employed to extract the volatile compounds from Xinjiang dried figs. The exactions were then analyzed using aroma extract dilution anal. (AEDA) based on gas chromatog.-mass spectrometry (GC-MS) and gas chromatog.-olfactometry (GC-O). Seventy-five aroma-active compounds were identified with flavor dilutions (FD) factors ranging from 1 to 2187. Aroma compounds with odor activity value (OAV) greater than 10 were subsequently used in aroma reconstitution and omission experiments Based on instrumental anal. and sensory evaluation, 22 compounds were identified as the key aroma compounds and eight of these were evaluated as the most important aroma contributors of Xinjiang dried figs, including heptanal, nonanal, linalool, benzyl benzoate, styrene, eugenol, 2-methoxy-4-vinylphenol, and vanillin. Moreover, three volatile components, including 2-methoxy-4-methylphenol, 2-methoxy-4-vinylphenol and ortho-guaiacol, were identified as key aroma compounds of dried figs and have not been reported previously. In the experiment, the researchers used many compounds, for example, 5-Ethyldihydrofuran-2(3H)-one (cas: 695-06-7Category: esters-buliding-blocks).
5-Ethyldihydrofuran-2(3H)-one (cas: 695-06-7) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Category: esters-buliding-blocks
