Abstract

The investigation was carried out to determine the extent of molds or spores contamination on wheat flour in three types (tow locally + one imported)on Babylon province.Molds were isolated from wheat flour samples by using PDA(Potato dextrose Agar) medium. Four replicates were inoculated with1 mL of different dilution of wheat flour into medium agar by spread plate technique and identified the mold by compound microscope with followed taxonomic keys of reference. The major genera of molds isolated according to decreasing frequency were Aspergillus, Penicillium, Fusarium, Cladosporium, Alternaria, Mucor, Rhizoctonia, Trichoderma, Rhizopus, Nigrospora, Bipolaris, Macrophomina. The coefficient correlation analysis revealed to positive correlation between moisture content and molds present(0.73).The results showed that differed species and genera association of mold in wheat flour after three months storage at two temperature(5 and 30 oC). The results indicated that stored at temperature 5 oC decrease the population and types of molds on wheat flour.
