Capillary electrophoresis–mass spectrometry-based approaches for food analysis and food metabolomics

Nowadays, there is a clear and growing demand for innovative analytical methods capable to provide reliable information of food components that allows not only to ensure the safety and quality of foods but also to reveal food–health associations. In this context, capillary electrophoresis coupled to mass spectrometry (CE-MS) is particularly useful in the analysis of polar and charged compounds. This review article aims to provide a critical overview of the most remarkable advances on the use of CE-MS-based approaches to assess different aspects of Food Science, including food quality and traceability, food safety, and food–health interactions. Besides, the most recent hardware and software developments are also discussed.
