Abstract

Toasted sesame seed oil was comprehensively analyzed. It was extracted using the SAFE (Solvent-Assisted Flavor Evaporation) technique. The extract was analyzed by GC and GC-MS on 2 phases and a total of 87 components were identified, confirmed, and are presented in this paper. The major components were methylpyrazine; 2,5-dimethylpyrazine; 2,6-dimethylpyrazine; 2-ethyl-3,6-dimethylpyrazine; furfuryl alcohol; and guaiacol. In addition, as part of this analysis, 2-ethyl-4-methyl-3-thiazoline and 2-isopropyl-4-methyl-3-thiazoline were confirmed as being present in a natural product for the first time. Their identification, confirmation, and sensory evaluation have been documented here.

摘要

对芝麻油进行了全面分析。它是使用 SAFE(溶剂辅助风味蒸发)技术提取的。提取物通过 GC 和 GC-MS 在 2 个阶段进行分析,共鉴定出 87 种成分,并在本文中进行了确认和呈现。主要成分是甲基吡嗪;2,5-二甲基吡嗪;2,6-二甲基吡嗪;2-乙基-3,6-二甲基吡嗪;糠醇和愈创木酚。此外,作为该分析的一部分,2-乙基-4-甲基-3-噻唑啉和 2-异丙基-4-甲基-3-噻唑啉首次被确认为天然产物中的存在物。本文记录了它们的鉴定、确认和感官评价。
