Development and validation of a liquid chromatography/linear ion trap mass spectrometry method for the quantitative determination of deoxynivalenol-3-glucoside in processed cereal-derived products

► Masked and native mycotoxins can coexist in the same food. ► Reliable correspondent analytical procedures are still lacking. ► A Linear Ion Trap LC-MS method for deoxynivalenol-3-glucoside was developed. ► Cross-reactivity of immunoaffinity columns was used to guarantee efficient cleanup. ► Method was validated applying a metrology approach and tested in bakery products.
