Distribution of Fungal Biomass Among Fine Bran, Coarse Bran, and Flour from Wheat Stored at Four Different Moisture Levels

• The fungal content of flour, fine bran, and coarse bran from wheat stored at moisture contents of 12, 16, 20, and 25% was determined as numbers of colony-forming units and as ergosterol levels. The highest values were found when wheat was stored at high moisture contents. In the sound wheat, 97% of the fungal biomass (ergosterol) was found in the bran fraction, which constituted only 31% of the kernel weight. At higher storage moisture, a more even distribution of fungal biomass was found. A weak correlation was found between the number of fungal propagules and ergosterol content. The high concentration of fungal biomass in the bran indicates that a potential mycotoxin hazard is associated with the use of bran to increase the content of dietary fiber in various foods.
