The aim of this study was to evaluate the impact and contribution of various drying surfaces (soil, cement, and tarpaulin) and raking frequencies (1 and 4/day) on the incidence of toxigenic molds, ochratoxin A (OTA) production, and on the overall cup quality during preparation of arabica and robusta coffee cherry in India. Two individual experimental batches (run 1 at the begin of harvest and run 2 at the end of harvest) were set up for the study. Results showed high incidence of molds in coffee dried on soil surface compared with that on cement and tarpaulin surfaces. In both arabica and robusta, OTA could be detected in Aspergillus ochraceus contaminated samples at the end of harvest. Raking of the cherries 4 times/day showed lower fungal incidence with no OTA levels detected. Overall, coffee cherry prepared by drying on tarpaulin surface with 4 rakings/day showed lower OTA and fungal incidence with good and acceptable cup quality, and this is recommended to be practiced at the farm level.
本研究旨在评估不同干燥表面（土壤、水泥和防水油布）和耙地频率（每天 1 次和 4 次）对印度阿拉比卡和罗布斯塔咖啡樱桃制备过程中产毒霉菌、赭曲霉毒素 A（OTA）产生的影响和贡献，以及对整体杯质量的影响。该研究设置了两个单独的实验批次（收获开始时进行的运行 1 和收获结束时进行的运行 2）。结果表明，与在水泥和防水油布表面干燥相比，在土壤表面干燥的咖啡中霉菌的发生率较高。在阿拉比卡和罗布斯塔中，在收获结束时，受赭曲霉污染的样本中均可检测到 OTA。每天耙地 4 次可降低霉菌的发生率，且未检测到 OTA 水平。总体而言，在防水油布表面干燥并每天耙地 4 次的咖啡樱桃中，OTA 和真菌的发生率较低，杯质量良好且可接受，因此建议在农场层面实施这一做法。
