The present invention relates to novel enzyme-comprising granules which are suitable as feed additives, and also to a method for production thereof. The invention also relates to the use of the enzyme-comprising granules in feed compositions and, in particular, pelleted feed compositions, which are obtainable using the enzyme-comprising granules. The particles of the enzyme granules have A. an enzyme-comprising core having a water content below 15% by weight, preferably in the range from 1 to 12% by weight, in particular in the range from 3 to 10% by weight, and especially in the range from 5 to 9% by weight, based on the weight of the enzyme-comprising core, which comprises i) 50 to 96.9% by weight, preferably 55 to 94.85% by weight, and in particular 60 to 89.7% by weight, of at least one solid support material suitable for feeds, ii) 0.1 to 10% by weight, preferably 0.15 to 5% by weight, in particular 0.2 to 2% by weight, and especially 0.3 to 1% by weight, of at least one water-soluble, neutral cellulose derivative, iii) 3 to 49.9% by weight, frequently 5 to 49.85% by weight, in particular 10 to 44.8% by weight, and especially 10 to 39.7% by weight, of at least one enzyme, the weight fractions of i), ii) and iii) in each case being based on the nonaqueous components of the core; and B) at least one hydrophobic coating arranged on the surface of the core, which coating comprises at least one hydrophobic material selected from waxes, saturated fatty acids, esters of saturated fatty acids, polyolefins and polyamides in an amount of at least 70% by weight, preferably at least 80% by weight, in particular at least 90% by weight, and especially at least 99% by weight, based on the total weight of the coating. |
