Determination of mycotoxins in nuts, cereals, legumes, and coffee beans and effectiveness of a selenium‐based decontamination treatment

Abstract Liquid chromatography‐tandem mass spectrometry (LC‐MS/MS) was used for the rapid quantification of multiple mycotoxins, specifically aflatoxins B 1 , 2 G and (AFB AFB AFG ), ochratoxin A (OTA), deoxynivalenol (DON), zearalenone (ZEN), in walnuts, pistachios, peanuts, coffee beans, rice, chickpeas from various countries. Total counts fungi, Aspergillus flavus, parasiticus were also assessed, along with effectiveness a decontamination treatment inorganic selenium to reduce mycotoxin levels. Of 78 samples tested, 69% contaminated mycotoxins. ZEN, predominant contaminant, detected all concentrations often exceeding maximum level, followed by (28% samples), DON (22%), (11%), (5.5%). The occurrence associated high proportions A. flavus . Complete removal walnuts roasted beans achieved aqueous selenium, while levels ZEN respectively lowered 65% 89% depending on commodity about 56% beans. While this novel is promising approach decontamination, it not intended replace safe practices upstream.
