Development of a Novel, Simultaneous Determination Method for Heterocyclic Amines and Mycotoxins in Fried Food by UPLC-MS/MS Combined With QuEChERS. [PDF]

Food Sci Nutr
• A novel QuEChERS‐UPLC‐MS/MS method was successfully developed for the simultaneous determination of two β‐carboline heterocyclic amines and seven mycotoxins in fried foods. ABSTRACT Dietary exposure to both processing contaminants and natural toxins in fried foods poses a potential health risk, but analytical methods for their simultaneous monitoring

QuEChERS as alternative extraction procedure in doping analyses

Drug Testing and Analysis, 2023
AbstractQuEChERS is a dispersive solid phase extraction commonly applied in food analysis for residues, such as pesticides or mycotoxins for more than 20 years. Due to the quick and easy sample preparation procedure, a QuEChERS method based on ammonium acetate combined with formic acid in acetonitrile was tested for the preparation of urine samples for
