Determination of Four Additives in Infant Food by Solid Phase Extraction-Liquid Chromatography-Tandem Mass Spectrometry
In this paper,a method for the determination of four commonly used food additives(coumarin,vanillin,methylvanillin and ethyl vanillin)in infant food was established.The results showed that the mass concentration of each target substance had a good linear relationship at 50 ng·mL-1 to 5 000 ng·mL-1,and the detection limit and quantification limit were 10 μg·kg-1 and 50 μg·kg-1,respectively.When the spike concentration was 50 μg·kg-1,100 μg·kg-1 and 500 μg·kg-1,the recovery rate was 81.72%to 102.13%,and the relative standard deviation was less than 10%.This method is accurate and reliable,and can be used for the detection of common additives in baby food matrices.
