摘要: 研究芝麻油的挥发性风味成分。采用顶空固相微萃取和气质联用技术,对自制芝麻油、商品芝麻油和两种芝麻香精中的挥发性成分进行检测,比较不同样品中挥发性物质及其相对含量的差异。结果表明:芝麻香精中含量较高的物质:吡嗪类、呋喃类、吡啶类、酮类和酚类物质,正是芝麻油中对香气贡献较大的物质。3,5-二甲基苯酚、3-甲基-1,2-环戊二酮、2-羟基-3-甲基-2-环戊烯-1-酮、环辛烷和2-硫代糠酯存在于2种芝麻香精中,在芝麻油中未检测到。而芝麻油中所含的噻唑类和吡咯类物质,在芝麻香精中未检测到。

Abstract: The volatile composition of commercial and laboratory-prepared sesame oil and two sesame flavor samples was analyzed by headspace solid phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS). Sesame flavor contained higher levels of volatile compounds such as pyrazines, furans, pyridines, ketones and phenols, which greatly contributed to the aroma of sesame oil. However, such compounds as 3,5-dimethyl-Phenol, 3-methyl-1, 2-cyclopentanedione, 2-hydroxy-3-methyl-2-cyclopenten-1-one, cyclooctane and 2-furfurylthiol were observed in sesame flavor but not in sesame oil. Thiazole and pyrrole were only detected in sesame oil but not in sesame flavor.

Key words: sesame oil, headspace solid-phase microextraction, gas chromatography-mass spectrometry, volatile compounds
