Abstract

Changes in the fluorescence behavior of fungal toxic metabolite ochratoxin were studied. The influence of ratio aqueous/organic solvent, the ionic composition of solution, and pH were investigated. The chromatographic separation under conditions yielding the highest fluorescence intensity were tested and compared with results obtained under commonly used chromatographic methods. The developed method was applied on analysis of spiked and naturally contaminated cereal samples.
