摘要:

以四川产花椒“贡椒”为原料,分别采用超临界CO2 和超声辅助溶剂萃取油树脂,通过对油树脂的GCMS分析和三角评价对比,发现两者香气成分存在差别,香气类型相近。超临界CO2 萃取花椒油树脂共检出33 种成分,主要成分芳樟醇占47.18%,其次是乙酸芳樟酯、D- 柠檬烯,各占12.11%、10.59%。超声辅助提取花椒油树脂检出18 种化合物。1- 乙基-6- 亚乙基环辛烯为含量最大的挥发性成分,占32.04%;其次是D- 柠檬烯、乙酸芳樟酯、芳樟醇,分别占20.92%、12.11%、10.92%。

Abstract:

Sichuan peppers from Qingxi town, Hanyuan county were subjected to supercritical carbon dioxide extraction (SCDE) or ultrasonic-assisted extraction (UAE) in order to obtain Sichuan pepper oil resin. SCDE-derived and UAE-derived Sichuan pepper oil resins were analyzed by GC-MS for their volatile composition and their aroma characteristics were evaluated by triangle test in terms of aroma similarity and intensity. The results revealed that SCDE-derived and UAE-derived Sichuan pepper oil resins had different volatile compositions but similar aroma characteristics. A total of 33 volatile compounds were found in SCDE-derived Sichuan pepper oil resin, of which, the predominant ones were 6-octadien-3-ol (47.18%), 3,7-dimethyl- 1,6-octadien-3-ol (12.11%) and D-Limonene (10.59%). The number of the volatile compounds found in UAE-derived Sichuan pepper oil resin was 18 and among these 18 volatile compounds, 1-ethyl-6-ethylidene cyclooctene had the highest relative content, reaching up to 32.04%, followed by D-Limonene (20.92%), linalyl acetate (12.11%) and 3,7-dimethyl-1,6-octadien-3-ol (10.92%).

Key words: Sichuan pepper, ultrasonic-assisted extraction, supercritical CO2 extraction, triangle test, GC-MS, oil resin
