This work reviews the current state-of-the-art of liquid chromatography coupled to high-resolution mass spectrometry (LC-HRMS) techniques applied to the analysis of pesticides in fruit-based and vegetable-based matrices. Nowadays, simultaneous trace analysis of hundreds of pesticides from different classes is required, preferably in just one run. The most commonly used QqQ-MS technology presents certain limitations in its application in a cost and effective way when analyzing a large number of pesticides. Thus, this review includes HRMS technology as a reliable complementary alternative allowing the analysis of a wide range of pesticides in food. Its capabilities and limitations in identifying, confirming and quantifying pesticides are discussed. HRMS instruments can adequately address such issues; however, the main drawbacks are as a result of insufficient prior optimization of the operational parameters during nontarget analysis in full-scan mode and due to software shortcomings.
