Abstract： A method for determining the migration amount of 4 citrate plasticizers in polylactic acid （PLA） coated paper tableware was established. The samples were soaked， extracted， centrifuged， determined by gas chromatography-mass spectrometry， and quantified by external standard method. The experimental results show that the method is simple， accurate and sensitive， and is suitable for the quantitative determination of four citric ester plasticizers in PLA coated paper tableware.
