JOURNAL OF FOOD SCIENCE(2011)
摘要
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.
