| Abstract: | "Wuliangye baijiu is one of the most famous Chinese liquors with a protected geographical indication. This study used LiChrolut((R)) EN-based solid-phase extraction (SPE) and fractionation combined with comprehensive two-dimensional chromatography-time-of-flight mass spectrometry (GCxGC-TOFMS) to unveil its volatile composition. The volatiles were isolated with LiChrolut((R)) EN-based SPE and traditional liquid-liquid extraction (LLE). The neutral/basic fractions from LLE and the SPE were fractionated on a LiChrolut((R)) EN SPE column and analyzed by comprehensive GCxGC-TOFMS. Compared with LLE, more esters and alcohols were detected in the SPE-based extraction. The SPE fractionation and GCxGC-TOFMS analysis resulted in the identification of about 500 volatile compounds in more than 3000 peaks of the Wuliangye baijiu. The approach simplifies the complex baijiu composition into functional group-based fractions for reliable identification and analysis. This study provided a confidence volatile identification approach for Chinese baijiu based on the SPE fractionation GCxGC-TOFMS" |
