| 中文摘要: |
| 通过了解不同植物油浸提的花椒油的挥发性成分（VOCs）特征，获得筛选花椒浸提用植物油的方法。利用气相色谱（GC）和离子迁移谱（IMS）联用技术对不同植物油浸提的花椒油的 VOCs 进行采集和分析。结果表明：不同植物油浸提的花椒油的VOCs 差异较大。GC-IMS 可有效分离各花椒油中极性相近的VOCs，并筛选出50 种离子峰强度变化明显的VOCs；通过二维数据可视化方式可显示各VOCs离子峰的差异；经数据降维处理后构建主成分分析模型，可将不同植物油浸提的花椒油根据浸提用植物油的不同进行聚类。相似度分析表明，与一级压榨菜籽花椒油相似度最高的是一级浸出菜籽花椒油，其次为大豆花椒油。因此，利用 GC-IMS 技术获取不同植物油浸提的花椒油产生的VOCs组成特征来筛选花椒油生产企业用的植物油原料的方法是可行的。 |

| Through understanding volatile components (VOCs) of Sichuan pepper oil extracted using different vegetable oils, the method for selecting vegetable oil was obtained. VOCs of Sichuan pepper oil extracted using different vegetable oils were collected and analyzed by GC-IMS. The results showed that VOCs of Sichuan pepper oil extracted using different vegetable oils had great differences. GC-IMS could effectively separate VOCs with similar polarity in Sichuan pepper oil, and 50 kinds of VOCs with obvious ion peak intensity change were screened out. The differences of VOCs ion peaks could be displayed by two-dimensional data visualization, the principal component analysis (PCA) model was established after data dimensionality reduction, and Sichuan pepper oil extracted using different vegetable oils could be clustered according to the different vegetable oils used for extraction. It was feasible to use GC-IMS to obtain VOCs composition characteristics of Sichuan pepper oil extracted using different vegetable oils to screen the vegetable oil raw materials for Sichuan pepper oil production enterprises. |
