Abstract:
A process for the preparation of enzyme pregranules with stable enzymatic activity comprising:providing a flour base;treating the flour base with dry superheated steam;grinding the flour base to obtain an organic flour grade;providing an enzyme or enzyme mixture;combining 0.01 to 20 parts by weight of the enzyme or enzyme mixture, calculated as the dry solids content thereof, with 80 to 99.99 parts by weight, including moisture, of the organic flour grade with an extraction rate of 30% to 100%, the total parts by weight of the enzyme or enzyme mixture and the organic flour grade equaling 100 parts by weight;combining up to 20 parts by weight of a granulation aid, calculated as anhydrous granulation aid with the enzyme or enzyme mixture and the organic flour grade, and sufficient water to adjust the moisture content of the moist granules to 20 to 50% by weight, based on the total weight of the moist granules, to form adhesive-free moist granules; anddrying the moist granules to form enzyme pregranules, wherein the process does not include a pelletizing step.
