The presence of bioactive benzoxazinoids (BXs) in mature whole grain and experimental bread products was recently shown. The aim of this study was to reveal the level of BXs in a broad range of commercial cereal products and discuss these findings in relation to ingredients and preparation processes. The concentrations of 11 BX compounds were determined by liquid chromatography–triple quadrupole mass spectrometry (LC–MS/MS) in 25 supermarket-available cereal food products. The total BX content varied from below the limit of detection to >500 μg/g dry matter (DM) with some degree of variation among different lots. The products W (Rugsandwich), H (Gulerodsrugbrød), L (Mørke Multikerneboller) and AA (Solsikkeklapper), which were all rich in rye-based ingredients, had a total BX concentration >300 μg/g DM. Double hexose derivatives of 2-hydroxy-1,4-benzoxazin-3-one (HBOA), 2,4-dihydroxy-1,4-benzoxazin-3-one (DIBOA) and 2-β-d-glucopyranosyloxy-4-hydroxy-1,4-benzoxazin-3-one (DIBOA-glc) were the major BXs in most products. Further studies into the health effects of BXs should be conducted, and future exploitation of these compounds seems possible.
