Here we explore the application of CE/MS/MS as an accurate and sensitive way to rapidly test for protein allergens in food. The workflow is based on a simple protein extraction step and the use of capillary electrophoresis (CE) hyphenated to a Thermo Scientific™ Orbitrap Fusion™ Lumos™ Tribrid™ mass spectrometer with an UVPD source for the characterization of the extracted proteins. The high mass accuracy and resolution, coupled to the efficient isoform separation and the different fragmentation modes allow for the rapid allergen identification and its origin.
