Abstract: The present disclosure discloses a method for accurately separating and identifying an oxidized triglyceride in frying oil, and belongs to the technical field of detection. In the present disclosure, the structure of the oxidized triglyceride (ox-TG) in the frying oil is identified by mass spectrometry first. It is found that after frying is conducted for 24 h, the ox-TG mainly includes epoxy ox-TG, hydroxyl ox-TG, and aldehyde ox-TG. Thus, the three types of ox-TG are selected as a template molecule to synthesize a surface molecularly imprinted polymer (SMIPs). Then, a polymer completely matched with the ox-TG template molecule in action site and spatial configuration is synthesized, and the specific ox-TG can be separated by using the SMIPs. According to the present disclosure, OXTG-SMIPs prepared by a molecular imprinting technology has good specificity, stability, and affinity, and accurate separation of the ox-TG in the frying oil can be achieved.
