摘要: 使用顶空固相微萃取及气相色谱-质谱联用技术(HS-SPME-GC-MS)对浓香型白酒酿造过程中涉及的原料、大曲 、窖泥、酒醅、基酒中的萜烯类化合物进行系统的检测。从9种酿造原料中检测出萜烯类化合物1338.20 ?g/kg,共计19种。8个时间段的大曲种检测出萜烯类化合物2380.32 ?g/kg ,共计18种。10种不同窖池的窖泥中共检测出萜烯类化合物2167.90 ?g/kg,共计13种。4个节点的酒醅中检测出萜类化合物702.66 ?g/kg,共计8种。两组基酒中共检测出9种萜烯类化合物,总浓度达338.57 ?g /kg。对比分析基酒与发酵过程中其他物质的萜烯类化合物,考虑基酒中的9种化合物,4种由粮食带入,3种由大曲带入,2种是蒸酒时由于高温由其他物质转换。

Abstract: The headspace solid-phase microextraction and gas chromatography-mass spectrometry (HS-SPME-GC-MS) techniques were used for the systematic determination of terpenoids in the raw materials, Daqu, cellar mud and fermented grains involved in the brewing process of Strong-flavor Baijiu. 1338.20 ?g/kg terpenoids were detected from 9 brewing raw materials, a total of 19 kinds. There were 18 kinds of terpenoids detected in Daqu species in 8 time periods, 2380.32 ?g/kg. A total of 2167.90 ?g/kg terpenoids were detected in the pit mud of 10 different pits, a total of 13 kinds. 702.66 ?g/kg terpenoids were detected in the fermented grains of 4 nodes, a total of 8 kinds. A total of 9 terpenoids were detected in the two groups of base liquor, with a total concentration of 338.57 ?g/kg. Comparing the terpenoids in the base wines with those in other substances during the fermentation process, it was considered that of the 9 compounds in the base liquor, 4 were brought in by the grain, 3 are brought in by Daqu and 2 were converted by other substances due to high temperatures during the steaming process.
