In a method for the recovery of enzymes, the activity of which after the treatment of starch-containing raw materials used for the production of fermentation alcohol is still not exhausted, the liquid phase containing solutions with still active enzymes after the first separation of the protein fraction is led to a fermentation, then a distillation. The wash water for the protein fraction is provided with a portion of the total amount of alpha-amylase necessary for starch hydrolysis of the raw material and then solids are again separated. The enzyme-containing wash water for the second separated solids is led back into the first enzymatic degradation stage simultaneously with a portion of the slop coming from the distillation.
