Abstract
A method of extracting bioactive compounds suitable for human and animal consumption from ethanol brewer's stillage. Stillage comprising spent grains suspended in water is provided from an ethanol plant. A lyophilized enzyme is added to the stillage. Ethanol is added to the stillage to form a mixture of ethanol and stillage. The mixture of ethanol and stillage is mixed and ethanol is extracted from the mixture to form a solution of bioactive compounds dissolved in extracted ethanol and spent grains containing the lyophilized enzyme. The bioactive compounds from the extracted ethanol are then separated by distillation or evaporation of the ethanol.
