目的了解烟台市售成品及散装食用油中塑化剂的迁移情况。方法样品前处理依据GB/T21911-2008,乙酸乙酯:环己烷(1:1,V:V)提取,凝胶渗透色谱装置净化,三重串联四级杆气质联用仪进行定性及定量分析。结果成品油中塑化剂有少量检出,而散装油的检出率很高,主要为邻苯二甲酸二(2-乙基)己酯(DEHP)70%、邻苯二甲酸二丁酯(DBP)60%、邻苯二甲酸二异丁酯(DIBP)45%和邻苯二甲酸二异壬酯(DINP)20%,超标率为DEHP 35.7%,DBP 58.3%。结论市民在购买食用油时应尽量购买成品油,购买散装的食用油时尽量不要使用非食品级的塑料桶盛放。
Objective To understand the migration of plasticizers in finished products and bulk edible oil in Yantai. Methods The samples were pretreated according to GB / T21911-2008, extracted with ethyl acetate: cyclohexane (1: 1, V: V), purified by gel permeation chromatography, and analyzed by triple quadrupole GC / MS. . Results There was a small amount of plasticizer in the finished product oil, while the detection rate of bulk oil was high, mainly including 70% of DEHP (dibutyl phthalate) (DBP) 60%, DIBP 45% and DINP 20%. The over-standard rate was 35.7% for DEHP and 58.3% for DBP. Conclusions Citizens should try their best to purchase refined oil when buying edible oil. Try not to use non-food grade plastic bucket when buying edible oil.
