Objective An analytical method for the detection of methylene dithiocyanate migration from food contact paper materials by high pressure liquid chromatography was established. Methods Methylene dithiocyanate migrated into the food simulants (water, 3%aqueous acetic acid solution, 10%aqueous ethanol solution and refined olive oil) was separated and detected by high pressure liquid chromatography coupled with diode array detector. The water-based food simulants were subjected to instrumental analysis directly and the oil-based food simulant was extracted by acetonitrile and then analyzed and quantitated with external standard method. Results This method showed a good linearity for methylene dithiocyanate in the range of 0.5~50 mg/L in the 3 water-based food simulants with the limit of quantification of 0.5 mg/L. The mean recoveries at three spiked levels were in the range of 88.2%~97.4%with relative standard deviations of 0.44%~6.54%. Me-thylene dithiocyanate exhibited a good linearity in the range of 1.0~20 mg/kg with the limit of quantification of 1.0 mg/kg. The mean recoveries at 3 spiked levels were between 99.3% and 104.7% with relative standard deviations of 0.75%~3.15%. Conclusion The method is accurate, simple, and rapid, and it can be used for the determination of methylene dithiocyanate in food contact paper materials.
