| 中文摘要: |
| 采用电子鼻对6种不同炒籽温度和7种不同原料产地油菜籽分别制取的两种类型浓香菜籽油进行了分析。结果表明：通过采集各样品气味信息，电子鼻能够灵敏地检测到浓香菜籽油的香气差异，经数据主成分分析判定，电子鼻既可以很好地区分不同炒籽温度的菜籽油样品，又可以区分不同原料产地的菜籽油样品，因此利用电子鼻技术能建立一种客观、快速区分不同工艺或不同原料浓香菜籽油的评价方法。 |
| 英文摘要: |
| Electronic nose was used to analyze rapeseed oils prepared by six different roasting temperatures rapeseeds and seven different raw material origins rapeseeds. The results showed that by collecting odor information of each rapeseed oil sample, electronic nose could detect the aroma difference of fragrant rapeseed oils, the electronic nose not only could distinguish rapeseed oils from different roasting temperatures well, but also could distinguish vegetable oil samples of different raw material origins combined with principal component analysis. So an objective, rapid evaluation method for distinguishing fragrant rapeseed oils of different processes or different materials by electronic nose could be established. |
