Ultra-Fast Analysis of Allergens using Capillary Electrophoresis Coupled to Mass Spectrometry and UVPD

The main goal of this work was to develop a simple and fast strategy allowing simultaneously the identification of allergens and the authentication of fish species. The identification of proteins in food matrices that cause sensitization in individuals or allergic reactions in those individuals already sensitized, represent a major concern for the food industry. Here we explore the application of CE/MS/MS as an accurate and sensitive way to rapidly test for protein allergens in food.
