Novel MS-based approaches and applications in food metabolomics

• Potential of novel mass-spectrometry (MS)-based approaches in food metabolomics.
• Study of food metabolome for food-safety assessment and quality control.
• Comparative metabolic profiling and fingerprinting to study food authenticity.
• Food authenticity, origin, quality, processing, and unintended effects of GM food.

This article gives an overview of some of the most recent trends in mass-spectrometry (MS)-based approaches and their application in food metabolomics. MS is a powerful analytical technique with excellent capabilities, and most emphasis is on descriptions of novel MS-based approaches, such as direct MS analysis using ambient ionization techniques or MS imaging. We also highlight recent applications of multi-dimensional chromatographic techniques and analytical multi-platforms.
