Abstract
Robusta coffee cherries collected before and during sun drying from two coffee farms in Thailand were examined for moulds producing ochratoxin A (OA). Aspergillus ochraceus was only detected in one sample, whereas Aspergillus carbonarius was isolated from 7 out of 14 samples. On γ-irradiated coffee cherries, each of the six tested A. carbonarius strains produced OA. More than 4800 μg kg−1 of toxin were detected under optimal conditions (25°C, aw 0.99). OA production was strongly reduced (230 μg kg−1) at an aw of 0.94.
