摘要
该研究采用顶空固相微萃取结合全二维气相色谱飞行时间质谱,对不同类型竹叶青酒的挥发性组分进行了解析。构建了竹叶青酒风味数据库,共定性出挥发性化合物883种,进一步通过香气数据库(Flavornet和Flavor DB)筛选出具有香气特征的363种香气化合物。其中酯类物质种类最多,萜类、醇类、醛类化合物次之。对不同类型竹叶青酒中香气成分的半定量浓度进行了正交偏最小二乘法判别分析,聚类热图分析和样本之间相关性等统计学分析,发现三大类产品可以明显区别,具有明显的物质特征性,竹叶青酒生产工艺的差异导致了系列产品酒之间的差异;样本之间相关性差异分析结果也表明了生产工艺的差异会导致系列产品酒之间的差异。该研究丰富了以竹叶青酒为代表的露酒的风味理论体系,也为竹叶青酒的风味研究提供了理论和数据支撑。
The volatile components of different types of Zhuyeqing were characterized by headspace solid-phase microextraction(HS-SPME)with comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry(GC×GC-TOFMS).GC×GC-TOFMS identified 883 volatile compounds,and 363 aroma compounds with aroma characteristics were screened through the aroma databases(Flavornet and Flavor DB).Among them,esters had the highest variety,followed by terpenes,alcohols,and aldehydes.The semi-quantitative concentrations of aroma components in different types of Zhuyeqing were analyzed by orthogonal partial least squares discriminant analysis,cluster heat map analysis,inter-sample correlation,and other statistical analyses.It was found that the three types of Zhuyeqing could be clearly distinguished from each other with obvious material characteristics,and the differences among series of samples were related to the different production process of Zhuyeqing.Besides,the results of the correlation analysis between the samples also showed that the production process could affect the differences among the series of Zhuyeqing.The study enriched the theoretical system of flavor chemistry of Lujiu,and provided basic data and theoretical basis for the study of flavor characteristics of Zhuyeqing.
