Selection of Determination Conditions for Ethyl Maltol in Plant Oil by Liquid Chromatography-Tandem Mass Spectrometry
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.
