Abstract: In this paper, the principle, instrument type and application status of high-resolution mass spectrometry technology in the direction of pesticide residues,additive screening,food authenticity identification, etc.,are expounded,and in viewof the diffculties faced bythe high-cost instrument,strong matrix interference, and insuficient data matching,the countermeasures such as optimized pre-treatment, intelligent analysis and standardization construction are proposed. The purpose of this study is to provide theoretical support for the promotion of high-resolution mass spectrometry technology and the improvement of food testing system.
Keywords: high-resolution mass spectrometry; food testing; standardization construction
