Abstract:

A method for the simultaneous determination of 30 mycotoxins in different feed products was developed using a QuEChERS pretreatment procedure coupled with ultra high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). The samples were extracted with 5 mL water and 5 mL acetonitrile containing 1% (v/v) formic acid. An aliquot of the supernatant was dried by nitrogen gas, re-dissolved by 1mL water containing 5 mmol/L ammonium acetate-acetonitrile (80:20, v/v), and analyzed by UHPLC-MS/MS. Matrix-matched calibration curves and internal standards were used for accurate quantification. Satisfactory recoveries at low, medium and high spiked levels were ranged from 72.0% to 118.4% (n=5). Good linear relationships were obtained, the correlation coefficients (r2) were greater than 0.99. The limits of detection (LODs, S/N=3) and the limits of quantification (LOQs, S/N=10) ranged from 0.7 μg/L to 20 μg/L and from 2 μg/L to 50 μg/L, respectively. The proposed method is simple, rapid and valuable, which can be a powerful tool for quantitative analysis of the 30 mycotoxins in premixed feed, concentrated feed and formula feed products.
