贵阳地区市售菜籽油中18种塑化剂含量及风险评估OACSTPCD

In order to understand the pollution level of phthalate esters(PAEs)plasticizers in rapeseed oil sold in Guiyang,65 plastic packaged rapeseed oils of different quality grades were bought from the shopping malls,supermarkets,farmers'markets and small workshops in Guiyang.According to GB 5009.271-2016 National Food Safety Standard-Determination of Phthalates in Foods,the SPE-GC-MS method was used to detect DBP,DEHP and other 18 kinds of phthalates in the rapeseed oil samples and analyze dietary intake risk of the phthalates.The results showed that,except for DAP,BMPP,DPP,DPhP,DINP and DNP,the remaining 12 PAEs in 65 rapeseed oil samples were detected to various degrees.DBP,DEHP and DBEP exceeded the national standard limit.The rate of exceeding the standard and the measured concentration range of the three plasticizers were 16.92%(0.006〜4.872 mg/kg),10.77%(0.085〜3.785 mg/kg)and 1.54%(0.088〜0.56 mg/kg),respectively.Rapeseed oil produced in small workshops had higher risk and the rate of phthalates exceeding the standard limits was 33.33%.Relevant government departments and consumers should pay attention to this issue.The intake risks of 18 plasticizers were in the acceptable range,but the quality and safety risks of rapeseed oil sold in Guiyang should be controlled from production,processing and storage.
