摘要
苯并芘是一种致癌物质,易在烧烤食品中出现。本文利用高效液相色谱法检测烧烤食品中的苯并芘含量,以正己烷为提取溶剂,提取15 min,选择流动相为乙腈+水=80+20,使用高效液相色谱仪检测。苯并芘的检出限为0.2μg·kg^(-1),定量限为0.5μg·kg^(-1)。本方法操作简单,回收率高,检测经济成本低,适合用于烧烤食品中苯并芘的测定。
Benzopyrene is a carcinogen that is easily found in barbecue food.In this paper,the benzopyrene content in barbecue food was detected by HPLC.N-hexane was used as extraction solvent for 15 min.The mobile phase was acetonitrile+water=80+20.The detection limit and quantitation limit of benzopyrene were 0.2μg·kg^(-1) and 0.5μg·kg^(-1),respectively.This method has the advantages of simple operation,high recovery and low cost,and is suitable for the determination of benzopyrene in barbecue food.
