Abstract

The analysis of spent brewer’s yeast slurry exhibited a five-day biochemical oxygen demand (B.O.D.) of 158400 mg/l at 20% yeast concentration. A treatment process for debittering was tried. The steps include removal of extraneous materials, reduction of the viscosity of slurry, debittering the yeast cells and centrifuging, washing and drying the debittered yeast-cell biomass in a drum dryer. Debittering was carried out successfully by adjusting the pH and temperature of the slurry. pH 10 at 50 “C of the slurry resulted in the complete debittering of the yeast cells in a single treatment without affecting the chemical and essential amino acid compositions.
