Mycological contamination of Ogiri (fermented sesame seeds) during production in Sierra Leone
- 48 Downloads
‘Ogiri’ (fermented sesame seeds) was prepared in the laboratory and at home by selected participants. No fungal participation was observed during the normal fermentation process. However, fungal contamination was observed when improper handling techniques were employed. Out of the 49 samples examined, 41 fungal isolates were made. Aspergillus spp were the dominant group irrespective of the locality. Toxigenic Aspergillus included A. flavus Link ex Fries, A. tamarii Kita and A. ochraceus Wilhelm. P. citrinum Thom was the only toxigenic Penicillium isolated. The role of the different types of wraps used for the fermentation, marketing and storage of the product was also determined.
