Ding, Wenwu published the artcileCharacterization of volatile compounds between industrial closed fermentation and traditional open fermentation doubanjiang-meju, Synthetic Route of 505-10-2, the main research area is alc ester volatile compound doubanjiang meju closed open fermentation.
Doubanjiang-meju has been used as an intermediate for producing Pixian Douban (PXDB) and contributes significantly to its flavor. In this study, a profiling anal. of volatile compounds in open fermented doubanjiang-meju (OFD) and closed fermented doubanjiang-meju (CFD) was performed with gas chromatog.-mass spectrometry (GC-MS) and gas chromatog.-olfactometry (GC-O). A total of 42 and 50 volatile compounds were identified in the OFD and CFD, resp. Compared with the OFD, more diversity and higher concentrations of alcs. and esters were found in the CFD. Ten and 12 volatile compounds were finally identified as the major aroma-active compounds in the OFD and CFD, resp., by the combined anal. of aroma intensity values and odor activity values (OAVs). The CFD had significantly stronger umami and soy sauce flavor but weaker beany when compared with the OFD (p < 0.05) by quant. descriptive anal. (QDA), which were basically consistent with intensity values of aroma compounds obtained with GC-O. The results indicated that the CFD had better characteristics of volatile compounds than those of the OFD, which provided a basis of further study for the closed fermentation process of tank fermenter. European Food Research and Technology published new progress about Acids Role: BSU (Biological Study, Unclassified), BIOL (Biological Study). 505-10-2 belongs to class alcohols-buliding-blocks, name is 3-(Methylthio)propan-1-ol, and the molecular formula is C4H10OS, Synthetic Route of 505-10-2.
