LC/MS Based Food Metabolomics

The power of Mass spectrometry (MS) coupled to liquid chromatography (LC–MS) with regard to the characterization of food matrices is presented. LC-MS is a very powerful analytical tool since it can provide direct qualitative and quantitative information about target molecules of interest. Quality of this information is influenced by the sample preparation procedure, the type of LC-MS used and the availability of dedicated database. This article highlights an overview of the applicability using LC-MS in various foods covering target and nontarget approaches. Furthermore, a brief description of the main food database, available as web-based resources, is presented.
