摘要:应用顶空固相微萃取(headspace solid-phase microextraction,HS-SPME)结合气相色谱/质谱联用(GC-MS),
对古井贡酒中高温大曲进行分析,共定性出 108 种挥发性化合物。通过考察不同样品量下化合物的 β 值,在 35
和 50 mg 样品量下,建立了应用多次顶空固相微萃取(multiple headspace solid-phase microextraction,MHS-SPME)
对醛酮类、酚类、含氮类、呋喃类、内酯类、萜烯类等 46 种化合物进行定量的方法。该方法回收率为 76.83%~
133.11%、最低检测限(limits of detection,LOD)低于 103.818 ng/g、相对标准偏差(RSD%)小于 21.34%,具
有较好的灵敏度和重复性。实验结果表明 MHS-SPME 可用于大曲中这 46 种化合物的定量,化合物含量在
(3645.79±442.43)~(6.32±1.03)ng/g 之间。该方法为定量大曲中挥发性成分提供了新的思路,研究结果也为企
业完善大曲质量评价体系提供了数据支持。

Abstract: Headspace solid-phase microextraction (HS-SPME) combined with gas chromatography-mass
spectrometry (GC-MS) was used to analyze the medium high temperature Daqu in Gujing Gongjiu, and a
total of 108 volatile compounds were identified. By examining the β values of the compounds under
different sample amounts, multiple headspace solid-phase microextraction (MHS-SPME) was applied to
quantify the aldehydes and ketones, phenols, nitrogen, furans, lactones, terpenes at the 35 and 50 mg
samples, and a total of 46 compounds were quantified. The recoveries of the method ranged from 76.83%~
133.11%, the limits of detection (LOD) were lower than 103.818 ng/g, and the relative standard deviation
(RSD%) were less than 21.34%, which showed the method had good sensitivity and repeatability. The
experimental results showed that MHS-SPME could be applied to the quantitative analysis of these 46
compounds in Daqu. The contents of measured compounds ranged from (3645.79±442.43) to (6.32±1.03) ng/g.
