The paper reveals the potential nutritive impact of the spent brewing yeast as component of feeding supplements for laying hens. The post-fermentation brewing yeast biomass was analyzed for total phenolic content, by applying extraction with methanol as solvent for samples of dried yeast biomass derived from an industrial brewing process. The obtained results suggest that drying process is reproducible and residual brewing yeast could be a source of polyphenols in order to be used for the development of bio-based nutritional feed solutions.
