The fate of deoxynivalenol and enniatins was studied during cooking of commercially available dry pasta in the Netherlands in 2014. Five samples containing relatively high levels of deoxynivalenol and/or enniatins were selected for the cooking experiment. Cooking was performed in duplicate on different days, under standardised conditions, simulating house-hold preparation. Samples were extracted with a mixture of acetonitrile/water followed by salt-induced partitioning. The extracts were analysed by LC–MS/MS. The method limits of detection were 8 μg/kg for deoxynivalenol, 10 μg/kg for enniatin A1 and 5 μg/kg for enniatins A, B and B1. During the cooking of the five dry pasta samples, 60% of the deoxynivalenol and 83–100% of the enniatins were retained in the cooked pasta. It is recommended to study food processing fate of mycotoxins through naturally contaminated materials (incurred materials).
