| 中文摘要: |
| 以贵州、四川、安徽、湖北、湖南、江苏和内蒙7省油菜籽为原料，经烘炒热榨制取浓香菜籽油，采用顶空固相微萃取（HS-SPME）和气相色谱-质谱（GC-MS）联用技术对浓香菜籽油中风味物质进行萃取和分离鉴定，在此基础上引入相对活度值法（ROAV）对鉴定出的风味物质进行活度分析，提取其中的特征风味物质。结果显示：甲烯丙基氰、4-异硫氰酸酯-1-丁烯、壬醛、2,3,5,6-四氟苯甲醚、2,5-二甲基吡嗪是不同产地浓香菜籽油的共同特征风味物质。同时因产地不同浓香菜籽油又表现出风味差异，贵州、四川菜籽油中硫甙降解产物含量较高，表现出浓郁的辛辣味；湖北菜籽油中吡嗪类化合物含量较高，表现出浓郁的焙烤香味。 |
| 英文摘要: |
| With rapeseeds from Guizhou, Sichuan, Anhui, Hubei, Hunan, Jiangsu and Inner Mongolia as raw materials, fragrant rapeseed oils were produced by roasting and hot pressing. The flavor substances in fragrant rapeseed oils were extracted using headspace solid phase microextraction(HS-SPME)and separated and identified using gas chromatography-mass spectrometry(GC-MS),then the typical flavor substances were distinguished by the relative odor activity value methods.The results indicated that methallyl cyanide, 4-isothiocyanato-1-butene,nonanal,2,3,5,6-tetrafluoroanisole, 2,5-dimethyl-pyrazine, were the common typical flavor substances in fragrant rapeseed oils from different regions. Meanwhile different fragrant rapeseed oils showed different flavor because of different regions, the Guizhou and Sichuan rapeseed oils presented strong spicy taste due to the high content of sulfur glucoside degradation products; the Hubei rapeseed oil showed a strong roasted smell for the high content of pyrazine compounds. |
