Abstract (en)
[origin: DE4041752A1] In the production of enzyme granulates with grain sizes from 0.1 to 2 mm, containing 2 to 20 % wt. proteases, lipases, amylases and/or cellulases, 10 to 50 % wt. swellable starch, 5 to 50 % wt. granulating agent, 3 to 12 % wt. water and not more than 10 % wt. water-soluble salt, by extruding an enzyme pre-mixture obtained by mixing a fermentation liquor cleared of insoluble components and concentrated with additives and spheroidizing the extrudate in a rounder, the use of relatively highly concentrated fermentation liquours has previously been necessary. By removing the insoluble components from the fermentation liquor by micro-filtration and mixing with additives which, in relation to the finished granulate, contains 10 to 35 % wt. cereal flour, it is possible, by the use of low-concentration fermentation liquors, to obtain highly active enzyme granulates with a long shelf life which are suitable for inclusion in washing and cleansing agents and are distinguished by uniform solubility properties in aqueous washing and cleansing baths.
