Tengzhou Haohan Chromatographic Instrument Technology Service Co., Ltd. has established a method for the determination of 18 phthalates (PAEs) in food by dispersive solid phase extraction. Pure oil samples were extracted and purified with n-hexane saturated acetonitrile; foods with lower oil content were extracted with 10% tert-butyl methyl ether-acetonitrile solution; the extracted solution was purified by the corresponding dispersive solid-phase extraction tube, and then performed by gas chromatography-mass spectrometry. Determination. The determination methods of PAEs in pure and low-fat foods were determined. The detection limit of 16 kinds of PAEs reached 1.5 mg / kg, and the detection limit of DIDP / DINP was 9.0 mg / kg. The recovery rate of pure oil samples was 80% ～ 110%, RSD <6.5%, and the recovery rate of low oil samples was 60% ～ 90%, RSD <8.4%. In addition, the determination method of distilled spirits was improved to improve the stability of the method.
