摘　　要：目的 了解杭州市售食用植物油中3-氯-1,2-丙二醇脂肪酸酯(3-MCPDEs)和2-氯-1,3-丙二醇脂肪酸酯(2-MCPDEs)的污染状况,为进一步研究提供技术支持。方法 利用非衍生化气相色谱-串联质谱法(GC-MS/MS)检测食用植物油中3-MCPDEs和2-MCPDEs含量。结果 在13类330份食用植物油中,3-MCPDEs和2-MCPDEs的检出率分别为96.4%和86.4%,含量范围分别为ND~7.98 mg/kg和ND~3.53 mg/kg,平均含量分别为0.77 mg/kg和0.36 mg/kg。其中,茶油、稻米油、芝麻油平均含量相对较高,橄榄油、核桃油、亚麻籽油和葵花籽油的平均含量相对较低。结论 食用植物油存在MCPDEs污染问题,不同植物油的种类和品牌污染程度不同,值得进一步研究和关注。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.
