Abstract Based on the research of sample pretreatment for food safety testing in recent years, a research-oriented instrument analysis experiment was designed and transformed from the scientific research achievement “improved QuEChERS method to extract and determine phthalate plasticizers in aquatic products”. A novel and environmental-friendly method for the analysis of phthalate esters (PAEs) in aquatic products was developed using the modified QuEChERS approach followed by gas chromatography-mass spectrometry (GC-MS) method. In teaching practice, students participated in the whole procedures of literature review, experimental design and results discussion, which stimulated students' enthusiasm and initiative in learning, and also improved students' scientific research ability and thesis writing ability.
