Screening methods for the detection of thirteen common mycotoxins

Area of Science:

• Analytical Chemistry
• Food Safety
• Toxicology

Background:

• Mycotoxins are toxic secondary metabolites produced by fungi that contaminate food and feed.
• Accurate and sensitive detection methods are crucial for ensuring food safety and preventing mycotoxicosis.

Purpose of the Study:

• To develop and validate a comprehensive screening method for thirteen common mycotoxins.
• To differentiate mycotoxins based on their chemical properties (neutral vs. acidic).
• To establish reliable detection limits and an effective extraction protocol.

Main Methods:

• Thin-layer chromatography (TLC) was employed for separating mycotoxins.
• Various solvent systems were tested to optimize RF value determination.
• Standard spray reagents were used to visualize mycotoxins on TLC plates.
• A general extraction procedure was developed for analyzing contaminated samples.

Main Results:

• Mycotoxins were successfully separated into neutral and acidic metabolite groups.
• RF values were determined for each mycotoxin in different solvent systems.
• Detection limits were established for the mycotoxins using specific spray reagents.
• An effective general extraction method for mycotoxin analysis was described.

Conclusions:

• The developed TLC method provides a reliable means for screening thirteen mycotoxins.
• Classification into neutral and acidic groups aids in identification and analysis.
• The established detection limits and extraction procedure are valuable for food safety monitoring.
