摘要:

利用顶空固相微萃取-气相色谱-质谱技术,建立了一种同时检测啤酒酿造大米中16 种风味物质的定量分析方法。通过研究不同因素对风味物质萃取效果的影响,最终确定顶空固相微萃取最佳萃取条件为:使用50/30 μmDVB/CAR/PDMS萃取头、40 ℃条件下萃取60 min。质谱的采集使用选择离子监控模式。该方法的线性良好(R2>0.99),准确性高(16 种物质的加标回收率在85.7%~118.0%之间),稳定性强(相对标准偏差均低于9.98%),操作过程简便,能准确检测啤酒酿造大米中16 种风味物质的含量,对啤酒风味和质量控制具有一定作用。

Abstract:

A gas chromatography-mass spectrometry (GC-MS) method coupled with headspace solid-phase microextraction
(HS-SPME) was developed for the determination of 16 flavor compounds in rice used for beer production. Through
investigation of various factors affecting the extraction and purification of flavor compounds, the optimum extraction
parameters were determined as extraction using a 50/30 μm DVB/CAR/PDMS-coated SPME fiber at 40 ℃ for 60 min. The
flavor compounds were quantified under selected ion monitoring mode (SIM). The recovery rates of 16 flavor compounds
were found to be in the range of 85.7%–118.0%, with relative standard deviation (RSD) less than 9.98%. The responses of
16 flavor compounds were found to be linear in the validated ranges (R2 > 0.99). This approach proved to be easy, simple and
accurate for determining 16 flavor compounds in rice. It provided a promising method for the evaluation and quality control
of beer flavor.

Key words: headspace solid-phase microextraction (HS-SPME), gas chromatography-mass spectrometry (GC-MS), rice used for beer production, flavor compounds
