建立食品和药品包装材料中3种抗氧化剂2,6-二叔丁基对甲基苯酚、丁基羟基茴香醚和特丁基对苯二酚的气相色谱检测法。样品以环己烷和异丙醇的混合液为提取溶剂,采用微波辅助萃取法进行提取。以Rtx~?-5为分析柱,氢火焰离子化检测器检测,外标法定量。3种抗氧化剂在5.0~100.0mg/L范围内线性关系良好(r~2>0.998)。在3个添加水平下,3种抗氧化剂的回收率范围为81.0%~95.2%,相对标准偏差小于10%。方法检出限范围为0.16~0.41mg/kg。该方法操作便捷,灵敏度高,可用于食品和药品包装材料中抗氧化剂的快速检测。

A comprehensive analytical method based on gas chroma tography was developed for measuring 3 antioxidants-2,6 di-tert-bu- tyl-4-methylphenol （ BHT）, butylated hydroxyanisole （BHA） and tertiary butylhydroquinone（TBHQ）, which were existed in food and drug packaging materials. The samples were extracted with cyclo hexane and isopropanol by microwave-assisted extraction. The ex tracts were separated by GC using an Rtx-5 column and quantified by external standard method with a FID detector. The calibration curves showed a good linearity （r^2 ...
