Abstract： As food safety issues become increasingly severe， the detection of harmful substances in food has become particularly important.Solid-phase extraction technology，as an eficient and simple sample pretreatment method，has been widely applied to the detection of contaminants in food.This paper summarizes the basic principles and classification of solid-phase extraction technology，discusses its applications and challenges in food testing， aiming to provide theoretical basis and practical guidance for the further developmentand optimization of solid-phase extraction technology in food testing.

Keywords： solid phase extraction; food detection; contaminant analysis; pesticide residues; heavy metals
