Determination of Migration of Ethyleneimine in Food Contact Paper and Paper Product by Ultra-high Performance Liquid Chromatography-Tandem Mass Spectrometry
An analytical method for migration amount of ethyleneimine in food contact paper and paper product was established by ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS).Formic acid aqueous solution(0.1%,volume fraction) and methanol were adopted as mobile phases,electrospray ionization(ESI) ion source was used to ionize the target,and multi-reaction monitoring mode was ultilized for detection.The results showed that there was good linear relationships for ethyleneimine in simulants of 4% acetic acid,10% ethanol,95% ethanol and isooctane in the mass concentration range of 0.003-0.05 mg/L,with the detection limits of 1 μg/L.Meanwhile,good linear relationship for ethyleneimine in simulant of olive oil existed in the range of 0.003-0.05 mg/kg,with a detection limit of 1 μg/kg.The spiked recoveries ranged from 96.0% to 102%,with the relative standard deviations(RSDs) of 1.6%-5.9%.20 batches of samples were selected for practical detection,of which 2 batches were found to contain ethyleneimine.The method was sensitive and accurate,and it was suitable for the determination of migration of ethyleneimine in food contact paper and paper products.
