摘　　要：采用气相色谱分析技术,可快速、准确地测定含乳饮料中塑化剂的含量.参照SN/T 2037-2007及GB/T21911-2008的要求,在上海市计算技术研究所自主研制生产的气相色谱仪上开发此专用分析方法,分析了含乳饮料中邻苯二甲酸二甲酯(DMP)、邻苯二甲酸二乙酯(DEP)、邻苯二甲酸二正辛酯(DnOP)等组分.实验保留时间和峰面积重复性的相对平均误差分别是0.271%和1.80%;3组分的空白回收率在60%以上.The gas chromatographic analysis technique can fast and accurate determine the plasticizer content in milk drinks. Refer to the SN/T 2037-2007 and GB/T 21911-2008 requirements, a specific analysis method is provided upon GC which is a self-developed product of the Shanghai Shangjiqnnli Analytical Instrument Co. , Ltd. Dimethyl phthalate （ DMP）, diethyl phthalate （ DEP）, dibutyl phthalate, n-dioctyl phthalate （DnOP） components in Milk Beverage were analyzed by this GC. The relative average error of retention time and peak area, 0.271% and 1.80%, respectively, the blank recycle ratio of the three components was above 60%.
