| 中文摘要: |
| 缩水甘油酯（GEs）痕量存在于精炼食用油中。食用油中缩水甘油酯检测方法主要包括间接检测法和直接检测法。间接检测法即将缩水甘油酯通过酯交换反应，解离出缩水甘油，再通过衍生化后进行GC-MS测定。直接检测法在不破坏缩水甘油酯结构的基础上，先经过或不经过样品净化步骤直接测定。对食用油中缩水甘油酯检测方法的样品处理过程、仪器条件、结果进行综述，并对检测方法的优缺点进行分析。 |
| 英文摘要: |
| Glycidyl esters (GEs) are trace contaminants in refined edible oils. The quantitative methods for GEs in edible oils included both indirect determination methods and direct determination methods. Indirect determination methods were based on transesterification of GEs to produce free glycidol and it was determined by GC-MS after derivatization. Direct determination methods directly quantified GEs with or without clean-up steps. The sample preparation, instrument conditions, and results of indirect methods and direct methods of GEs in edible oils were described, and their advantages and disadvantages were also discussed. |
