Sixteen strains of moulds isolated from traditional cheese wagashi produced in Benin
have been screened for their ability to produce mycotoxins in Sucrose/Magnesium
sulphate/ potassium (Kalium) nitrate/ Yeast extract (SMKY) broth media by thin layer
chromatography. Griseofulvin was use as standard to determine retention factor value
and to identify secondary metabolites produced. All strains were previously cultivated
in Malt Extract Agar. Qualitative ability of mycotoxin production of these strains was
performed by fluorescence emission under ultra violet light at 365 nm after extraction
of metabolites with chloroform. Results obtained showed that A. flavus produced
aflatoxin B2 whereas Penicillium citrinum strain produced citrinin. Aspergillus
versicolor, A. ochraceus, A. tamarii, A niger, A terreus, A. nidulans, A. carbonarius,
A. fisheri, A. candidus, A. wentii, P. griseofulvum, P. islandicum, F. poae and F.
verticillioides had also produced mycotoxins which were not confirmed because of
the lack of reference data . In sum, all strains of moulds investigated are toxinogenic.
These secondary metabolites detected and above all aflatoxin B2 and citrinin could be
produced inside cheese wagashi. Their presence in wagashi must be investigated in
order to evaluate health hazardous for cheese wagashi consumers. |
