Abstract
A method of treating chemical pulp for the manufacture of microfibrillated cellulose includes the following steps: a) providing a hemicellulose containing pulp, b) refining the pulp in at least one step and treating the pulp with one or more wood degrading enzymes at a relatively low enzyme dosage, and c) homogenizing the pulp thus providing the microfibrillated cellulose. A microfibrillated cellulose obtainable by the method is also provided. The microfibrillated cellulose can be used in food products, paper products, composite materials, coatings or in rheology modifiers (e.g. drilling muds).
