%X Research on the human exposure to Cylindrospermopsin (CYN) via consumption of contaminated food is of greatinterest for risk assessment purposes. The aim of this work is to evaluate for the first time the CYN bioaccessibilityin contaminated vegetables (uncooked lettuce and spinach, and boiled spinach) after an in vitro digestionmodel, including the salivar, gastric and duodenal phases and, colonic fermentation under lactic acid bacteria.The results obtained showed that the digestion processes are able to diminish CYN levels, mainly in the colonicphase, especially in combination with the boiling treatment, decreasing CYN levels in a significant way.Moreover, the potential decomposition products in a pure CYN solution and in CYN-contaminated vegetableswere evaluated using UHPLC-MS/MS Orbitrap. Under the conditions assayed, only two diastereoisomers of thesame fragment with m/z 292.09617 have been detected in all the analysed samples, with the exception ofdigested vegetables. Therefore, in terms of risk assessment, the digestion seems to play an important role inreducing the final bioaccesibility of CYN, and the consumption of cooked vegetables (spinach) would be safer incomparison to raw vegetables.
