D 8535 Abstract A process for the purification of enzyme solutions In a process for the purification and deodorization of aqueous enzyme solutions obtained by fermentation of bacteria or fungi, the invention seeks to improve the enzyme yield and the filterability of the precipitates to be removed. This is done by adding to the enzyme solution at least one masking agent selected from the group consist- ing of - acids of boron and/or water-soluble salts thereof, - sulfurous acid and/or water-soluble salts thereof, - hydroxycarboxylic acids and/or water-soluble salts thereof, - polyhydric alcohols and subsequently forming a precipitate by addition of two water-soluble, mutually precipitating ionic compounds in any order, optionally adding further adsorbents and subse- quently removing the solids from the enzyme solution.
