Aflatoxigenic and ochratoxigenic moulds and their toxins in tree nuts on Serbian market
In this study, moulds and mycotoxins presence in different tree nuts were investigated. The results showed that all of the 25 samples were contaminated with moulds. Mean values of total mould count varied from 1-4.9 cfu per grain. The most frequent species in hazelnut samples were Rhizopus...

description |
In this study, moulds and mycotoxins presence in different tree nuts were
investigated. The results showed that all of the 25 samples were
contaminated with moulds. Mean values of total mould count varied from 1-4.9
cfu per grain. The most frequent species in hazelnut samples were Rhizopus
oryzae (32.2%) and Aspergillus niger (28.9%). In walnuts A. niger (75.6%),
in cashews also A. niger (42.4%) while in pistachio samples Alternaria
alternata (20.7%), and Cladosporium cladosporioides (20.7%) were the most
dominant. Rhizopus oligosporus was the only identified species in all almond
samples (100%). Using Enzyme Linked Immunosorbent Assay (ELISA), the
presence of total aflatoxins and ochratoxin A was examinated. In all
analyzed samples, levels of ochratoxin A were below the limit of detection.
Total aflatoxins were detected only in walnut samples with average
concentration of 7.1 μg/kg. |
