Abstract: With the growing demand for food safety detection, traditional analytical methods face significant technical challenges, such as lengthy detection cycles and low efficiency, particularly when dealing with complex food matrices and large sample volumes. Ambient ionization mass spectrometry (AIMS) has emerged as a cutting-edge rapid analytical tool, demonstrating remarkable advantages in food safety detection due to its minimal or simplified sample preparation requirements. Characterized by high analytical speed and efficiency, AIMS has been successfully applied to the rapid detection of various hazardous substances in food, including pesticide and veterinary drug residues, chemical contaminants, and toxins. Furthermore, ambient ionization mass spectrometry imaging (AIMSI) provides spatial distribution information of chemical compounds on sample surfaces, offering a visual basis for in situ sampling. This review systematically outlines the development and classification of AIMS, with a focus on its current applications in the field of food safety. Additionally, it delves into the latest research advancements in AIMSI. The aim of this review is to provide theoretical foundations and technical guidance for the selection and application of AIMS and its imaging technologies in rapid food safety detection.
