Freeze-dried strawberries and pears, raisins, sliced roasted almonds,
and hazelnuts were investigated for their qualitative and quantitative
mycoflora on four different media. The foodstuffs investigated showed
relatively low infestation rates. Slightly higher fungus counts were
observed in the case of almonds, while strawberries, hazelnuts, raisin
s, and pears (in decreasing order) were contaminated only to a minor d
egree. The mycoflora was dominated by molds of the genera Aspergillus
and Penicillium and fungi of the Mucoraceae. Most fungus isolates coul
d be enumerated from DRBC, followed by PDA and DG-18, while 7.5% MSA s
howed only low effectiveness. Minor differences were seen when the num
ber of different species/genera from each medium were compared with ea
ch other. DRBC allows the isolation of the broadest spectrum of fungi.
Differences between the remaining media were small.
