摘  要:
利用乙腈直接提取油脂中的丁基羟基茴香醚(BHA)、二叔丁基羟基甲苯(BHT)和特丁基对苯二酚(TBHQ),利用气相色谱法进行分析测定。结果表明,3种抗氧化剂加标回收率为86.9%~104.8%,BHA和BHT的最低检出限均为2 mg/kg,TBHQ的最低检出限为5 mg/kg,相对标准偏差为2.5%~3.2%,线性范围为1~200μg/mL,线性相关系数均大于0.999。该方法简便、快速、稳定、可靠,适用于油脂及含油脂食品中BHA、BHT和TBHQ的快速定量检测。

摘  要:
In this study,three antioxidants butylhydroxy anisd(BHA),butylated hydroxytoluene(BHT),and tertiary butylhydroquinone(TBHQ) were extracted by acetonitrile from oils directly and analyzed by gas chromatography.The recoveries of three antioxidants ranged from 86.9% to 104.8%.The results showed that the detection limits of BHA,BHT and TBHQ were 2,2 and 5 mg/kg,respectively.The relative standard deviations were from 2.5% to 3.2%.The linear ranges were from 1 to 200 μg/mL,with their correlation coefficients were higher than 0.999.This method was simple,rapid and stable.It can be used for the fast determination of BHA,BHT and TBHQ in oil foods.
