Zhang, Jinglin published the artcileCharacterization of aroma-active compounds in Jasminum sambac concrete by aroma extract dilution analysis and odour activity value, Category: esters-buliding-blocks, the main research area is linalool cis3hexanyl acetate eugenol aroma active compound Jasminum.
Jasminum sambac is a flower and usually used in food, cosmetics or other chem. industries for its unique flavor characteristics in China. However, mol. sensory technologies have not applied to identify aroma-active compounds in J sambac concrete. In this study, gas chromatog.-olfactometry (GC-O), gas chromatog.-mass spectrometry and solvent-assisted flavor evaporation were applied to isolate the odorants in three Chinese J sambac concrete (E1, E2 and E3) obtained from different companies. A total of forty-nine, forty-eight, thirty-nine odorants were screened by GC-O with aroma extract dilution anal. in E1, E2 and E3, resp. The higher flavor dilution (FD) factors were linalool (19 683-59 049, floral), Me anthranilate (6561-19 683, grape-like) and benzyl acetate (2187-19 683, floral). Twenty-two aroma compounds were quantitated by gas chromatog.-flame ionization detection with internal standard, and then their odor activity values were obtained. Linalool, cis-3-hexenyl acetate, linalyl acetate, eugenol and Me salicylate contributed greatly to the aroma of J sambac concretes. The aroma recombination model was established by mixing twenty-two key odorants based on their measured concentrations, and the result revealed that the overall aroma profile was similar to that of the original sample. These results proved basic data for improvement of the national standard of jasmine concrete.
