The phosphated starch preferably has a mean degree of phosphation ranging from 1.5 to 2.5. Carrier materials include starch, cereal flour, cellulose, alkali metal aluminosilicate, layer silicate and alkali metal salts. Enzymes include proteases, lipases, amylases and cellulases. A preferred carrier material contains water-swellable starch, sucrose, cereal flour and cellulose powder. The granulation auxiliary may contain a co-granulation auxiliary selected from polyethylene glycol having an average molecular weight of from 200 to 6,000, 1,2-propylene glycol and a poly-ethoxylate having a specified formula.

Abstract: An enzyme granule and means for producing the enzyme granule is presented. The enzyme granule is composed of an enzyme, a carrier material, and a coating system of 5 to 70 percent by weight fine-particle inorganic water-insoluble pigment, 45 to 90 percent by weight of a water-soluble organic substance having a melting point of from 40 to 70° C., and 0 to 30 percent by weight of a flow improver. The granule can be produced by mixing an aqueous enzyme liquid with an inorganic or organic carrier material to form an enzyme compound, extruding the enzyme compound, spheronizing the extrudate, and applying an outer coating layer of the coating system listed above to form an enzyme granule having a mean particle size of 0.8 to 1.4 millimeters. The coated enzyme granule has increased storage stability, even coloration, reduced odor, and releases enzyme activity quickly in water. The enzyme granule is useful in solid detergents.

Abstract: Scent intensifying washing and cleaning detergents or components for these detergents are manufactured in which a solid and essentially water-free premix is produced, said premis being comprised of washing and cleaning detergent compounds and/or washing and cleaning detergent materials. The premix contains at least 0.1 wt. % perfume referring to the premix and is subjected to granulation or compacted agglomeration. By virtue of the water-free method, subsequent drying steps do not apply in which the prefume is entirely or partially vaporized. The homogenous incorporation of the prefume leads to a substantially increased fragrance of both the product as well as the articles which are dampened or dried, especially textiles.

Furthermore, a process for the preparation of the enzyme granules is disclosed.

Abstract: A process is provided for deodorizing an aqueous culture broth composition by: (a) providing an aqueous culture broth composition containing odorous compounds in spray form; (b) providing a stream of superheated steam; (c) providing a spray zone in vacuo; (d) simultaneously introducing both the aqueous composition of (a) and the superheated steam into the spray zone causing the odorous compounds to be entrained in the superheated steam, thus forming a deodorized aqueous culture broth composition; (e) removing the superheated steam containing the entrained odorous compounds from the spray zone; and (f) discharging the deodorized aqueous culture broth composition from the spray zone. Preferably, the culture broth composition is maintained at a temperature of less than 50.degree. C. in the spray zone to prevent inactivation of temperature-sensitive materials such as enzymes. Pressure in the spray zone may be about 10 to 250 mbar and temperature of the superheated steam can be up to 250.degree. C.

Abstract: The invention relates to an optimized process for conditioning a stream of superheated steam laden with steam-volatile organic components by condensation of the steam phase with recovery of the heat of condensation and at least partial separation of the steam-volatile organic components from the water-based condensate. The process operates with a first heat exchange stage in which the continuously introduced vapor stream is combined with a circulated and cooled liquid stream of condensed vapors. In a following second energy transfer stage, heat is indirectly removed from the liquid stream thus heated. A sidestream is removed from the liquid circuit of the condensed vapors and subjected to separation in a membrane process while the rest of the liquid stream is returned to the first stage.
