Ultra-High-Performance Liquid Chromatography in Food Metabolomics: Food Quality and Authenticity

Metabolomics is an emerging eld in analytical chemistry and can be regarded as the end point of the “omics” cascade. In its most ambitious global form, metabolomics tries to comprehensively analyze known and unknown metabolites in a given biological sample-metabolome-dealing with the analysis of low molecular mass compounds (<1500 Da) such as amino acids, peptides, organic acids, vitamins, polyphenols alkaloids, nucleic acids, carbohydrates, and other small molecules [1].
