摘要:

建立果汁饮料及其包装材料中邻苯二甲酸二(2-乙基己基)酯(DEHP)的气相色谱-质谱联用测定方法(GC-MS),在1~50mg/L的质量浓度范围内具有良好的线性关系(r=0.9978),检测限为0.4mg/L,回收率在87.84%~105.23%,相对标准偏差小于7%。该方法操作简单,重现性好。同时对果汁饮料中的DEHP进行溯源分析,可为食品安全性评价提供参考价值。

Abstract:

A rapid, simple, and repeatable method was established to determine bis(2-ethylhexyl) phthalate (DEHP) in
juice by gas chromatography-mass spectrometry (GC-MS). The results showed that its linear range was 1.0–50.0 mg/L (R2 =
0.9978) and the detection limit for DEHP was 0.4 mg/L. Average recovery rates ranged between 87.84% and 105.23% with
relative standard deviation of less than 7%. Therefore, the GC-MS method is suitable for quantifying DEHP in juice and
providing a useful guideline to trace the source of DEHP in juice.

Key words: diethylhexyl phthalate, juice, gas chromatography-mass spectrometry, source tracing
