Abstract

Mycoflora of 75 cans of different batches and brands of pistachio nuts purchased in the Sultanate of Oman was studied. A number of fungi were isolated, with percentages of contaminated nuts [average between brands ] as follows: Aspergillus niger 14.8%, Penicillium spp. 13.6%, A flavus 9.7%, A nidulans 1.6%, and < l % for Cladosporium cladosporoides, Alternaria alternata , A ochraceeus and Ulocadium consortiale. Significant differences were found among the batches and brands contaminated by A flavus. A flatoxin B, was found only in one sample out of 1.5 assayed at a level of 2 ug/kg.
