    Abstract:

    Objective To investigate the contamination level of 3-monochloropropane-1，2-diol ester （3-MCPDEs） and 2-monochloropropane-1，3-diol ester （2-MCPDEs） in edible vegetable oils sold in Hangzhou City， and provide technical support for further study.Methods Non-derivatization gas chromatography-tandem mass spectrometry was used to determine 3-MCPDEs and 2-MCPDEs in edible vegetable oil.Results In 330 samples of 13 kinds of edible vegetable oils， the detection rate of 3-MCPDEs was 96.4%， the content range was ND-7.98 mg/kg， the average value was 0.77 mg/kg， the detection rate of 2-MCPDEs was 86. 4%， the content range was ND-3.53 mg/kg，the average value was 0.36 mg/kg. From the perspective of vegetable oil varieties， the mean values of tea oil， rice oil and sesame oil were relatively high， and the mean values of olive oil， walnut oil， linseed oil and sunflower oil were relatively low.Conclusion The contamination of MCPDEs is common in edible vegetable oils， and the severity of contamination is affected by the types and brands of vegetable oils.
