摘要: 采用同时蒸馏萃取法提取传统小麦酱中的挥发性成分,以气-质联用结合气相色谱-嗅闻技术,对传统小麦酱中的活性香气成分进行分离鉴定。结果共鉴定出42种挥发性化合物,占色谱流出组分总量的72.835%,在传统小麦酱中的含量为102.845μg/g,包括醛类6种、酯类10种、酸类6种、烃类8种、醇类1种、杂环类化合物7种、酮类1种,其他化合物3种。用气相色谱-嗅闻技术分离出25种活性香气成分,其中芳香萃取物稀释分析稀释因子较高的有乙酸、异戊醛、糠醛、3-甲硫基丙醛、二甲基三硫醚、1-辛烯-3-醇和四甲基吡嗪等。

Abstract: The volatile composition of traditionally fermented wheat paste was extracted by simultaneous distillation extraction (SDE) and analyzed by gas chromatography and mass spectrometry (GC-MS) coupled with gas chromatography and olfactometry (GC-O). Totally 42 volatile compounds comprising aldehydes (6), esters (10), acids (6), hydrocarbons (8), alcohols (1), heterocycles (7), ketones (1) and miscellaneous compounds (3) were identified, accounting for 72.835% of total peak area and 102.845 μg/g in traditionally fermented wheat paste. A total of 25 aroma compounds acetic acid were identified by GC-O. Among these compounds, 3-methylbutanal, furfural, methional, dimethyl trisulfide, 1-octen-3-ol and tetramethyl pyrazine was determined by aroma extract dilution analysis to show a higher flavour dilution factor.
