摘　　要：目的了解浙江省市售食用植物油中2-氯丙醇(2-monochloropropanediol,2-MCPD)酯污染水平,评估居民经植物油摄入2-MCPD酯暴露水平。方法2016—2020年从浙江省农贸市场、商店、网购等场所采集不同种类植物油404份,采用气相色谱-质谱法检测2-MCPD酯含量,分析污染水平;结合2008年浙江省城乡居民消费量调查结果,评估不同年龄组人群经植物油的2-MCPD酯暴露水平。结果样品中2-MCPD酯检出率为82.7%(334/404),平均含量为0.32 mg/kg,其中山茶油中2-MCPD酯平均含量最高(1.23 mg/kg),其次是稻米油(0.69 mg/kg);葵花籽油、橄榄油、大豆油平均值相对较低,分别为0.11、0.12和0.13 mg/kg。不同年份采集的植物油、同品牌不同种类的植物油及不同品牌花生油中2-MCPD酯含量差异均有统计学意义(P<0.05),不同品牌玉米油中2-MCPD酯含量差异无统计学意义。植物油食用人群中,不同年龄组人群摄入2-MCPD酯平均暴露量为0.21~0.69μg/(kg·BW·d)。结论2016—2020年浙江省市售植物油中普遍存在2-MCPD酯污染,污染严重程度受植物油的种类、品牌的影响;植物油高消费人群和一般人群中4~10岁人群2-MCPD酯摄入水平均较高。OBJECTIVE To investigate the occurrence data for 2-chloropropanol(2-MCPD)ester in edible vegetable oils purchased in Zhejiang Province during 2016-2020,and to estimate dietary exposures of 2-MCPD ester via vegetable oil.METHODS A total of 404 samples of edible oils were collected from markets,stores,online shopping in Zhejiang Province,the occurrence of 2-MCPD ester was detected by gas chromatography mass spectrometry from 2016-2020.Data of vegetable oils consumption was obtained from the survey result of urban and rural residents in Zhejiang Province in 2008.The exposure levels of 2-chloropropanol ester was calculated for people aged 4-6,7-10,11-17,18-59 and 60 years old and older from the consumption of vegetable oils.RESULTS The detection rate of 2-MCPD esters in 404 samples was 82.7%(334/404)with the mean level of 0.32 mg/kg.Among them,the mean content of camellia oil was the highest with 1.23 mg/kg,followed by rice oil(0.69 mg/kg);sunflower oil,olive oil and soybean oil have relatively low average values,respectively with 0.11,0.12 and 0.13 mg/kg.There are significant differences in 2-MCPD ester content in different types of edible oils of the same brand(P<0.05),the content of 2-MCPD ester in different brands of peanut oil was significant(P<0.05),but in different brands of corn oil was not statistically significant.Among the edible vegetable oil consumers,the average exposure of 2-MCPD esters in different age groups ranged from 0.21 to 0.69μg/(kg·BW·d).CONCLUSION 2-MCPD esters pollution is widespread in vegetable oils,the severity of pollution was affected by the type and brand of the edible vegetable oil,and the intake of 2-MCPD esters was relatively high among people with high vegetable oil consumption and the general population of 4-10 years old.
