Abstract:
A method of preparing an activity-stable and low-dust enzyme granulate for washing and cleaning applications comprising;(a) forming an adhesion-free wet granulate including combining: (i) a flour obtained by grinding an organic flour source that has been treated with dry superheated steam to a degree of grinding of 30 to 100% wherein the organic flour source is selected from the group consisting of cereal grains, legumes and fruits of the Malvaceae family; (ii) an enzyme or enzyme mixture; and (iii) a sufficient amount of water in a high-speed mixer to form the adhesion-free wet granulate, wherein 75 to 99.9 parts by weight of the flour and 0.1 to 25 parts by weight of the enzyme or enzyme mixture is used to form the wet granulate and wherein the wet granulate has a moisture content of 15 to 50% and granulate particles in the size range from 0.2 to 2.0 mm; and(b) drying the wet granulate to obtain an activity-stable and low-dust enzyme granulate having moisture content of about 3 to 12%.
