Acidity of water extract of dried fodder yeasts.Peer-reviewed article

M. RUT, L. ADÁMEK, F. ŠTROS

The causes of a high acidity of water extracts of dried fodder yeasts produced in Seliko Kojetín were studied. The high acidity is affected by phosphates and products of biomass degradation that occurred during a wrong thermal treatment a temperature internal between 40 and50 °Chas be quickly overcome since under these temperatures acidic compounds are produced and excreted from the cells. To obtain the product with a standard acidity it is recommended to heat quickly the yeast cream above80 °Cwith the retention tome of 3 to 6 min immediately after the centrifugation.
