Search for B-1 aflatoxin and similar fluorescent compounds in 'misso'

Following previous studies on the investigation of B-1 Aflatoxin in food samples (4,5) we report in this paper the results obtained using thin layer chromatography (TLC) with three different solvent systems and spectrophotometric analysis in order to differentiate actual B-1 Aflatoxin and Aflatoxin-like substances. Twenty 'Misso' samples were studied and we could detect Aflatoxin in 3 of them. An Aflatoxin-suspected substance was also isolated. No Aflatoxin-producing Aspergillus was isolated from the samples analysed.
