Area of Science:

  • Food safety analysis
  • Analytical chemistry
  • Mycotoxicology

Background:

  • Mycotoxins like deoxynivalenol, T-2 toxin, HT-2 toxin, and zearalenone pose significant risks in food commodities.
  • Accurate and simultaneous detection methods are crucial for ensuring food safety and regulatory compliance.

Purpose of the Study:

  • To develop and describe a method for the simultaneous determination of four key mycotoxins in wheat and biscuit matrices.
  • To compare the effectiveness of different clean-up strategies, including immunoaffinity column (IAC) and multifunctional columns, in mitigating ion suppression.

Main Methods:

  • Simultaneous determination using liquid chromatography/electrospray ionization/tandem mass spectrometry (LC/ESI/MS/MS).
  • Immunoaffinity extraction (IAC) for selective mycotoxin capture.
  • Evaluation of multifunctional columns and IAC for sample clean-up and reduction of ion suppression.

Main Results:

  • Successful simultaneous quantification of deoxynivalenol, T-2 toxin, HT-2 toxin, and zearalenone.
  • Demonstration of the method's applicability to complex food matrices like wheat and biscuits.
  • Comparative analysis highlighting the impact of clean-up techniques on analytical performance.

Conclusions:

  • The developed LC/ESI/MS/MS method coupled with IAC provides a reliable approach for simultaneous mycotoxin analysis.
  • Effective clean-up strategies are essential for accurate mycotoxin determination in food products.
  • This method contributes to enhanced food safety monitoring and risk assessment.
