The present invention relates to a method for manufacturing microfibrillated polysaccharide, preferably microfibrillated cellulose. The invention also relates to microfibrillated cellulose obtainable by the method and use of the microfibrillated cellulose. The method of manufacturing microfibrillated cellulose comprises the following steps: a) Providing a hemicellulose containing pulp, b) Providing wood degrading enzymes c) Mixing pulp and enzymes d) Keeping the mixture in a continuous, flowing system of essentially cylindrical geometry (for example in a plug-flow reactor), e) Conveying the mixture to one or more mixing zones for recirculating and homogenizing the mixture, and f) Harvesting microfibrillated cellulose with a relatively narrow size distribution during the recirculation. |
