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. 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 coupled to
the efficient isoform separation and the different fragmentation modes allow for the rapid
allergen identification and its origin.
