  • Publication number: 20020028267
    Abstract: The production of an activitystable and low dust enzyme granulate for use in food technology applications or for working into recipes for food technology application for example, in the production of baked goods and farinaceous products, in starch processing, or in brewing, is described. The activitystable and lowdust enzyme granulates obtained according to the production methods and their use in food technology are also described. In another, special aspect of the invention, the use of especially selected flours are very generally described as an auxiliary (for example, as a carrier or filler) for the production of enzyme granulates for various application purposes.
    Type: Application

  • Patent number: 6248706
    Abstract: The preparation of an activity-stable and low-dust enzyme granulate for washing and cleaning applications, e.g. for use in granular washing and cleaning agent compositions, is described. Also described are the activity-stable and low-dust enzyme granulates obtained in accordance with the method of preparation as well as their use in washing and cleaning applications. In addition, in a special aspect of the invention, the use of specially selected flours as auxiliary agents for the preparation of enzyme granulates for diverse application purposes is described.

  • Patent number: 6221406
    Abstract: The invention relates to the preparation of enzyme pregranules with stable activity which can be incorporated into particles of a granular animal feed. The invention further relates to the pregranules with stable activity which are obtained by the preparative processes and can be incorporated into granular animal feeds.

  • Patent number: 6204236
    Abstract: New enzyme granulates are described which contain an organic disulfide compound (R—S—S—R), particularly they contain the free amino acid cystine, optionally mixed with the amino acid cysteine. The new enzyme granulates are for us in detergent and cleanser compositions, particularly in dishwasher compositions, and they have properties. For example, insofar as protecting objects made of silver against tarnishing, for example, dishes, cutlery, and other objects to be cleaned.

  • Patent number: 5739091
    Abstract: Enzyme granules which comprise in their composition, in addition to the enzyme, water-soluble and water-insoluble fillers, binders and if appropriate other granulating auxiliaries, a formate of an alkali metal or alkaline earth metal and if appropriate reducing sugars being added to them to stabilize the enzyme, are described. All the enzymes customary for detergents and cleaning purposes, in particular alkaline proteases, can be processed into the enzyme granules. A process for the preparation of these enzyme granules and their use in pulverulent detergent formulations are also described.
