The analytical requirements for food testing have increased significantly in recent years. On the one hand, because food fraud is becoming an ever‐greater challenge worldwide, and on the other hand because food safety is often difficult to monitor due to the far‐reaching trade chains. In addition, the expectations of consumers on the quality of food have increased, and they are demanding extensive information. Cutting‐edge analytical methods are required to meet these demands. In this context, non‐targeted metabolomics strategies using mass and nuclear magnetic resonance spectrometers (mass spectrometry [MS]) have proven to be very suitable. MS‐based approaches are of particular importance as they provide a comparatively high analytical coverage of the metabolome. Accordingly, the efficiency to address even challenging issues is high. A variety of hardware developments, which are explained in this review, have contributed to these advances. In addition, the potential of future developments is highlighted, some of which are currently not yet commercially available or only used to a comparatively small extent but are expected to gain in importance in the coming years.
