Moniliformin is extracted with water and quantified with liquid chromatography tandem mass spectrometry, and its presence confirmed with liquid chromatography-Orbitrap-high-resolution mass spectrometry. The method was validated for flour, bread, pasta and maize samples in terms of linearity, matrix effect, recovery, repeatability and limit of quantification. Quantification was conducted by matrix-matched calibration. Positive samples were confirmed by standard addition. Recovery ranged from 77 to 114% and repeatability from 1 to 14%. The limit of quantification, defined as the lowest concentration tested at which the validation criteria of recovery and repeatability were fulfilled, was 10 µg/kg. The method was applied to 102 cereal-based food samples collected in the Netherlands and Germany. Moniliformin was not detected in bread samples. One of 22 flour samples contained moniliformin at 10.6 µg/kg. Moniliformin occurred in seven out of 25 pasta samples at levels around 10 µg/kg. Moniliformin (MON) was present in eight out of 23 maize products at levels ranging from 12 to 207 µg/kg. info:eu-repo/grantAgreement/ES/DGA/A01 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.854 2017 TOXICOLOGY 37 / 94 = 0.394 2017 Q2 T2 MYCOLOGY 9 / 29 = 0.31 2017 Q2 T1 0.684 2017 Biotechnology 2017 Q2 Toxicology 2017 Q2 Microbiology 2017 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Van Dam, Ruud Spanjer, Martien de Stoppelaar, Joyce Mol, Hans de Nijs, Monique López, Patricia 2008 640 Universidad de Zaragoza Dpto.
