| Summary: | In order to investigate the effects of different raw materials on a Baijiu brewed with different glutinous rice and millet mixed with sorghum, the glutinous rice, red glutinous rice and millet were mixed with sorghum in a 1∶1 ratio, respectively, and the Baijiu was brewed by the traditional process of sauce-flavor (Jiangxiangxing) Baijiu. The volatile flavor compounds and metabolites in the Baijiu were analyzed by headspace solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS), which results were subjected to principal component analysis (PCA) and partial least squares-discriminant analysis (PLS-DA). The results showed that a total of 91 volatile flavor components were identified, 48 significantly different volatile flavor substances, mainly ethyl laurate, ethyl caprate and furfural, etc. were screened out based on the variable importance projection (VIP) value>1.0 and P<0.05. A total of 125 significantly different metabolites were screened out, with taurine, β-alanine, aspartate and glutamic acid as the main substances. The results of cluster analysis (CA) showed that the millet and sorghum Baijiu and the red glutinous rice and sorghum Baijiu were grouped into one category, and the glutinous rice and sorghum Baijiu was grouped into one category alone. |
