Abstract
To establish a GC-MS method for determination of 14 photo-initiators in fatty food. The homogeneous samples were extracted by acetone-hexane(2∶8,v:v) for 15 min at room temperature. The supernatant was purified by HLB column, and the eluent was then collected, which was further purified by PSA. The purified eluent was centrifuged and determined by GC-MS. The recoveries were between 73.0%～92.4% at spiked levels of 0.000 2～0.001 0 mg/kg, and the relative standard deviation of the methods were 4.1%～8.9%, with the LOD ranging from 0.02~0.20 μg/kg. It was in accordance with the requirement of technical parameters for analysis with fast and simple determination and high sensitivity. It was suitable for the simultaneous determination of 14 photo-initiators in fatty food.
