| 摘要：地沟油是我国当前面临的食品安全问题之一。地沟油的鉴别指标是用来判断未知油脂是否含有地沟油的标准。常见的地沟油鉴别指标包括内源性组分和外源性杂质。对色谱技术在地沟油中脂肪酸、胆固醇、微量杂质成分等鉴别指标检测中的应用进行了综述，指出应继续筛查地沟油的特异性指标，同时地沟油宜采用多种方法进行检测，综合各种方法的结果进行辨别，以提高鉴别的准确性。 |

| Abstract：In China, one of the top concerns in food safety is swill-cooked dirty oil. The identification indexs of swill-cooked dirty oil are used to judge whether the unknown oil contains swill-cooked dirty oil or not. Common identification indexes of swill-cooked dirty oil include endogenous components and exogenous impurities. Meanwhile, the application of chromatographic technology in the determination of fatty acids, cholesterol and trace impurities in swill-cooked dirty oil was reviewed. It was pointed that the specific indicators of swill-cooked dirty oil should be screened continuously. At the same time, the swill-cooked dirty oil should be detected by a variety of different methods, and the detection results of various methods should be combined for identification to improve the identification accuracy. |
