摘 要:本文建立了一种同时测定食品包装中6种爽滑剂(月桂酰胺、棕榈酰胺、油酸酰胺、硬脂酰胺、芥酸酰胺、山嵛酰胺)的气相色谱-质谱方法,从源头上对食品包装的质量进行控制。样品经粉碎、甲醇超声提取后,注入气相色谱-质谱仪进行分析。优化进样口温度,使用高温缓升的升温程序实现色谱分离,选择定量定性离子进行质谱测定。结果表明,6种酰胺的质量浓度在各自线性范围内线性关系良好,测得其定量限为0.3~22 mg/kg。以空白样品为基体,加入6种酰胺的混合标准溶液进行回收试验,测得回收率为80.0%~95.0%,测定值的相对标准偏差(n=6)为4.6%~7.9%。该方法灵敏、准确,精密度高,重复性好,适用于食品包装材料中6种爽滑剂含量的检测。In this paper,a gas chromatography-mass spectrometry(GC-MS)method was established for the simultaneous determination of six slip agents(Lauramide,Hexadecanamide,Oleamide,Stearamide,Erucamide and Behenamide)in food packaging so as to control the quality of food packaging from the source.The samples were crushed,ultrasonically extracted with methanol,and then injected into a gas chromatography-mass spectrometer for analysis.The inlet temperature was optimized,chromatographic separation achieved using a high-temperature ramp-up program,and quantitative qualitative ions selected for mass spectrometry.The results showed that the mass concentrations of the six amides had a good linear relationship in their respective linear ranges,and the limits of quantification were 0.3-22 mg/kg.With the blank sample as the matrix,and by adding the mixed standard solution of 6 amides for recovery test,the recoveries of the compounds in spiked samples were 80.0%-95.0%,and the relative standard deviations(n=6)of the measured values were 4.6%-7.9%.This method is sensitive,accurate,with high precision and good repeatability,and is suitable for the detection of six slipping agents in food packaging materials.
