Fan, Qian published the artcileCharacterization of key aroma compounds in Laobaigan Chinese Baijiu by GC×GC-TOF/MS and means of molecular sensory science, Application of Ethyl nonanoate, the main research area is aroma compound laobaigan baijiu GCTOFMS analysis.
Laobaigan (LBG) Baijiu is recognized as one of the famous Chinese liquors due to its unique flavor characteristics. However, its key aroma-active volatiles are still unknown. In this study, 414 volatile chems. in the LBG Baijiu were initially detected by comprehensive two-dimensional gas chromatog.-time-of-flight mass spectrometry (GC×GC-TOF/MS). Then, 52 of them were determined by sample dilution anal. (SDA) for screen of aroma-active compounds Based on their odor-activity values (OAVs) that were determined by the external standard method performed on the GC×GC-TOF/MS, 32 volatile compounds were further recognized as important odorants, which were reconstituted to simulate and validate the aroma profile of the LBG Baijiu. Moreover, omission experiments were conducted to corroborate the importance of key odorants. As a result, nine aroma compounds were finally confirmed as the key aroma-active compounds of the LBG Baijiu.
Flavour and Fragrance Journal published new progress about Baijiu. 123-29-5 belongs to class esters-buliding-blocks, name is Ethyl nonanoate, and the molecular formula is C11H22O2, Application of Ethyl nonanoate.
