Their grains are recognized for their nutritional benefits; however, there is a higher level of polyphenism. Meanwhile, the chemical food safety of pseudocereals remains poorly documented. Here, we applied untargeted and targeted metabolomics approaches by LC-MS to achieve both: i) a comprehensive chemical mapping of pseudocereal samples collected in the Andes; and ii) a quantifi-cation of their contents in emerging mycotoxins. An inventory of the fungal community was also realized to better know the fungi present in these grains. Metabotyping permitted to add new insights into the chemotax-onomy of pseudocereals, confirming the previously established phylotranscriptomic clades. Sixteen samples from Peru (out of 27) and one from France (out of one) were contaminated with Beauvericin, an emerging mycotoxin. Several mycotoxigenic fungi were detected, including Aspergillus sp., Penicillium sp., and Alternaria sp. specialized Andean pseudecereals Metabotyping Mycotoxins Fungal communities PEROU BOLIVIE EQUATEUR ANDES 054 076 020 407 135134 [10 ] 2023 0308-8146 https://www.documentation.ird.fr/hor/fdi:010086805 10.1016/j.foodchem.2022.135134 0308-8146 [F B010086805] https://www.documentation.ird.fr/hor/fdi:010086805 https://www.documentation.ird.fr/intranet/publi/2023-02/010086805.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2023-02-08 2025-02-24 fdi:010086805 fre
