摘要：

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 gamma -irradiated coffee cherries, each of the six tested A. carbonarius strains produced OA. More than 4800 mug kg(-1) of toxin were detected under optimal conditions (25 degreesC, a(w) 0.99). OA production was strongly reduced (230 mug kg(-1)) at an a(w) of 0.94. (C) 2001 Elsevier Science B.V. All rights reserved.
