This study set out to assess the relative importance of sound and unsound beans in a batch of coffee with regard to ochratoxin A (OTA) contamination. Initially, unsound beans were found to account for 95% of contamination in a batch of coffee, whatever the methods used for post-harvest processing. It was also found that beans displaying traces of attacks by Colletotrichum kahawae were the greatest contributors to OTA contamination. In a second stage, the study compared the contamination of sound beans with that of beans attacked by Colletotrichum kahawae. On average, beans attacked by Colletotrichum kahawae had a statistically higher OTA content than sound beans (18.0 microg kg(-1) as opposed to 1.2 microg kg(-1)). In addition, the average OTA content in unsound beans varied depending on growing conditions.
本研究旨在评估一批咖啡中，坏豆相对于好豆在赭曲霉毒素 A（OTA）污染方面的相对重要性。最初，无论采用何种收获后处理方法，坏豆都占到了这批咖啡中 OTA 污染的 95%。此外，研究还发现，受到胶孢炭疽菌侵染的咖啡豆是 OTA 污染的最大贡献者。在第二阶段，研究比较了好豆和受到胶孢炭疽菌侵染的豆之间的污染情况。平均而言，受到胶孢炭疽菌侵染的豆的 OTA 含量明显高于好豆（18.0μg/kg 对 1.2μg/kg）。此外，坏豆的平均 OTA 含量还因种植条件而异。
