摘要
本文对液相色谱-串联质谱法测定食用植物油中乙基麦芽酚的方法进行了条件优化.结果表明,在 10~200 ng·mL-1 线性良好,相关系数R2=0.997 2,检出限为0.3 μg·kg-1,定量限为1 μg·kg-1,平均回收率为92.4%~98.6%,相对标准偏差为2.4%~3.8%.该方法适用于食用植物油样品中乙基麦芽酚的日常检测.
Abstract
The conditions for the determination of ethyl maltol in edible vegetable oil by liquid chromatography-tandem mass spectrometry were optimized.The results showed that the linearity was good at 10~200 ng·mL-1,the correlation coefficient R2=0.997 2,the detection limit was 0.3 μg·kg-1,the limit of quantitation was 1 μg·kg-1,the average recovery was 92.4%~98.6%,and the relative standard deviation was 2.4%~3.8%.This method is suitable for the daily detection of ethyl maltol in edible vegetable oil samples.
