摘 要：
利用气相色谱/三重串联四级杆质谱技术,对植物油中抗氧化剂BHA、BHT和TBHQ检测进行了方法建立及实际样品测试。分析结果表明,该方法对食用植物油中BHA、BHT和TBHQ三种抗氧化剂的检测,线性范围为0.5μg/L～50μg/L,线性相关系数均大于0.999,仪器检出限分别为0.1μg/L、0.04μg/L和0.2μg/L,样品中的检出限为0.1μg/L、0.04μg/L和0.2mg/kg。三种组份三个浓度梯度(0.5μg/L、5μg/L和50mg/kg)的平均回收率均在85.0%-110.0%之间,相对标准偏差在2.53%～8.37%之间。该方法具有简便、快速、准确、无毒等特点,可应用于大豆油、花生油、调和油、菜子油等样品检测中,结果令人满意。

摘 要：
A method for the determination of BHA,BHT and TBHQ in edible vegetation oil by gas chromatography coupled with triple quadrupole mass spectrometry(GC/QQQ/MS/M S)was studied.The linear range of detection changed from 0.5 μ g/L to 50 μ g/L(r> 0.999).The detection limits of machine of the three kinds of antioxidants were 0.1 μ g/L,0.04 μ g/L and 0.2 μ g/L and those in the sample were 0.1mg/ kg,0.04mg/kg and 0.2mg/kg.The recoveries of three different concentrations(0.5,5and 50mg/kg) were ranged between 85.0%-110.0% and the relative standard deviations were ranged from 2.53%to 8.37%.This method is simple,quick,accurate and safe.The method can be applied in determination of BHA,BHT and TBHQ in edible vegetation oil samples with satisfactory results.
