摘要
为了探索使用不同酒曲酿造黍米黄酒对酒体风味产生的影响,使用三种不同酒曲(安琪黄酒曲、大曲、红曲)酿制黍米黄酒,采用顶空-固相微萃取-气相色谱-质谱(HS-SPME-GC-MS)技术对三种黍米黄酒中的挥发性风味物质进行检测.结果表明,在大曲、红曲、安琪黄酒曲酿造的黍米黄酒中分别检测到235、239、165个峰信号,对从不同酒样中鉴定出的32种高丰度挥发性风味物质进一步分析,其中11种挥发性风味物质为三种黍米黄酒所共有;安琪黄酒曲酿造的黍米黄酒中特有的挥发性风味物质为庚醇、苯乙醛和苯乙酮,大曲酿造的黍米黄酒中特有的挥发性风味物质为γ-丁内酯和糠醛,红曲酿造的黍米黄酒中特有的挥发性风味物质为2-壬酮.使用不同酒曲对黍米黄酒风味影响大,主要体现在通过变量重要性投影(VIP)值＞1筛选出的异戊醇、苯甲醛、糠醛等9种差异挥发性风味物质中.
Abstract
In order to explore the effect of different Jiuqu on the flavor of the millet Huangjiu,millet Huangjiu was brewed using three different Jiuqu(Angel Huangjiuqu,Daqu,and Hongqu),and the volatile flavor compounds in the three types of millet Huangjiu were detected by HS-SPME-GC-MS.The results showed that 235,239,and 165 peak signals were detected in the millet Huangjiu brewed with Daqu,Hongqu,and Angel Huangjiuqu,respec-tively.The 32 volatile flavor compounds with high abundance identified from different Huangjiu samples were analyzed,among which 11 volatile flavor compounds were common to the three millet Huangjiu.The unique volatile flavor compounds in the millet Huangjiu brewed with Angel Huangjiuqu were heptanol,phenylacetaldehyde,and acetophenone,while the unique volatile flavor compounds in the millet Huangjiu brewed with Daqu were γ-butanone and furfural,and the unique volatile flavor compounds in the millet Huangjiu brewed with Hongqu were 2-nonone.The use of different Jiuqu had a significant impact on the flavor of millet Huangjiu,mainly reflected in the 9 different volatile flavor compounds such as isoamyl alcohol,benzaldehyde,furfural and so on which were screened by variable importance in the projection(VIP)value＞1.
