奶茶杯内膜中增塑剂含量的检测分析

摘要

The high-performance liquid chromatographic method was developed for the determination of 3 phthalic acid esters (PAEs) in Milk-Tea cup of internal film,including di-butyl phthalate (DBP),di-(2-ethylhexyl) phthalate (DEHP)and dioctyl phthalate (DOP) 3 kinds of plasticizers to lipophilic simulations of liquid ( milk, vegetable oil, isooctane ) .The results showed that, tea cups lining materials through lipid soluble analog fluid after soaking with DEP and DBP detection, DOP not detected, DBP detectable quantities in the EU directive 2007/19/EC in a prescribed range, DEP detection was much greater than that of British farming fishing Ministry of food provisions daily tolerance.%采用高效液相色谱法测定奶茶杯内膜材料中的邻苯二甲酸（2-乙基己基）酯（DEHP）、邻苯二甲酸二丁酯（DBP）、邻苯二甲酸二辛脂（DOP）3种增塑剂向脂溶性模拟液（牛奶、植物油、异辛烷）中的迁移溶出量。结果表明，奶茶杯内膜材料经过脂溶性模拟液浸泡后有DEHP和DBP的检出，DOP未检出，DBP检出量在欧盟指令2007/19/EC的规定范围内，DEHP检出量远大于英国农渔食品部规定的的每日耐受量。
