title: Mycoflora and natural aflatoxin contamination in dried quince seeds from Jammu, India.
abstract: Eighty two samples of dried quince seeds, obtained from the markets of Jammu province, were examined for mycoflora by different isolation techniques. A total of 27 fungal species belonging to 11 genera were recovered and identified from these samples. The predominant fungal genera encountered were Aspergillus, Penicillium and Fusarium. In view of the predominance of Aspergillus flavus, a known producer of aflatoxins, screening of the fungal contaminated samples was carried out for total aflatoxin levels using high performance liquid chromatography (HPLC). Twenty one aflatoxin positive samples contained 8.07-33.45 μg g(-1) and 0.05-3946.97 μg g(-1) AFB1 and AFB2 respectively. These results suggest that biochemical composition of dried quince seeds, along with climatic conditions of the region seem to be very favourable for aflatoxin production by toxigenic strains of A. flavus. Therefore, monitoring of aflatoxins in dried quince seeds is recommended for this region.
