目的 了解合肥市售白酒和饮料中邻苯二甲酸酯类塑化剂的污染水平和迁移污染状况。方法 依据《2013年国家食品污染和有害因素风险工作手册》和GB/T 21928-2008《食品塑料包装材料中邻苯二甲酸酯的测定》,采用优化的毛细管气相色谱-三重四级杆串联质谱方法,对合肥市商场超市销售的22件白酒和15件饮料样品,进行邻苯二甲酸二甲酯(DMP)、邻苯二甲酸二乙酯(DEP)、邻苯二甲酸二异丁酯(DIBP)、邻苯二甲酸二丁酯(DBP)等16种邻苯二甲酸酯类化合物的检测。结果 22件白酒样品和15件饮料样品均检测出邻苯二甲酸酯类化合物,16种邻苯二甲酸酯类化合物检测的最大值分别为2.15 ~6 345.27 μg/L和9.35~5 756.82 μg/L,白酒样品中有2件邻苯二甲酸二丁酯(DBP)的含量超过300.00 μg/L,超标率为9.09%;有5件邻苯二甲酸二(2-乙基)己酯(DEHP)的含量超过1 500.00 μg/L,超标率为22.73%。饮料样品中有4件邻苯二甲酸二丁酯(DBP)的含量超过300.00μg/L,超标率为26.67%,有7件邻苯二甲酸二(2-乙基)己酯(DEHP)的含量超过1 500.00μg/L,超标率为46.67%。结论 白酒和饮料受到了塑化剂污染,潜在的健康危害和风险还需要进一步全面评估。

Objective To investigate the phthalates contamination and pollution status of plasticizer migration in white spirits and beverage in Hefei markets. Methods According to National Food Pollution and Hazardous Factors Risk Manual(2013) and GB/T 21928-2008 Determination of Phthalate Esters in Foods using optimized gas chromatography-mass-mass spectrometry coupled detector detection, 16 type of phthalates (dimethyl phthalate, diethyl phthalate, diisobutyl phthalate, et al) were detected in 22 whiter spirits and 15 beverage samples. Results The detection rate of phthalic acid esters were 100% in the 22 whiter spirits samples and 15 beverage samples. And the maximum detection of 16 kinds of phthalic acid esters were among 2.15 μg/L -6345.27 μg/L and 9.35 μg/L -5 756.82 μg/L, the diisobutyl phthalate of 2 samples were more than 300.00 μg/L with the over standard rate of 9.09%, the bis (2-ethylhexyl) phthalate of 5 samples were more than 1 500.00 μg/L with the over standard rate of 22.73% in the 22 whiter spirits samples; the diisobutyl phthalate of 4 samples were more than 300.00μg/L with the over standard rate of 26.67%, the bis (2-ethylhexyl) phthalate of 7 samples were more than 1 500.00μg/L with the over standard rate of 46.67% in the 15 beverage samples. Conclusion The white spirit and beverage contained a variety of PAEs, so the potential harm and risk need to be further evaluated.
