A miniaturized QuEChERS and UPLC-MS/MS method for the determination of mycotoxins in cashew nuts.

This study aimed to develop and validate a multi-mycotoxin analysis method applied to cashew nuts by employing a miniaturized QuEChERS method followed by determination by ultra-performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS). Satisfactory recoveries for the concentrations 1, 10 and 30 ng g, ranging from 66% (fumonisin B) to 110% (ochratoxin A) and relative standard deviations lower than 9% (fumonisin B) were obtained for the target compounds. Limits of quantification ranged from 0.
