It has a higher price than other vegetable oils because of the high price of its raw materials, and different processing techniques also result in products of different quality levels, which can command different prices. In the market, there is a persistent problem of adulteration of sesame oil, driven by economic interests. The screening of volatile markers used to distinguish the authenticity of sesame oil raw materials and production processes is therefore very important.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>In this work, six markers related to the production processes and raw materials of sesame oil were screened by gas chromatography\u2013tandem mass spectrometry (GC\u2010MS\/MS) combined with chemometric analysis. They were 3\u2010methyl\u20102\u2010butanone, 2\u2010ethyl\u20105\u2010methyl\u2010pyrazine, guaiacol, 2,6\u2010dimethyl\u2010pyrazine, 5\u2010methyl furfural, and ethyl\u2010pyrazine. The concentration of these markers in sesame oil is between 10 and1000 times that found in other vegetable oils. However, only 3\u2010methyl\u20102\u2010butanone and 2\u2010ethyl\u20105\u2010methyl\u2010pyrazine differed significantly as the result of the use of different production processes. Except for guaiacol, which was mainly derived from raw materials, the other five compounds mentioned above all result from the Maillard reaction during thermal processing. The six compounds mentioned above are sufficient to distinguish fraud involving sesame oil raw materials and production processes, and can identify accurately adulteration levels of 30% concentration.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>In this study, the classification markers can identify the adulteration of sesame oil accurately. These six compounds are therefore important for the authenticity of sesame oil and provide a theoretical basis for the rapid and accurate identification of the authenticity of sesame oil. \u00a9 2021
