摘要： 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).

摘要： The present invention provides a method for extracting polymeric pentose, preferably xylan, from a polymeric pentose containing liquid/slurry, preferably black liquor, comprising the following steps: a) providing a polymeric pentose containing liquid/slurry; b) concentrating the polymeric pentose by membrane separation of a said polymeric pentose containing liquid/slurry; and c) adding alcohol to the concentrate obtained in step b) and subsequently acidifying said concentrate obtained in step b) for precipitating polymeric pentose whereby a polymeric pentose product, or an intermediate polymeric pentose product, is obtained. In this above way polymeric pentose, e.g. xylan, is separated whereby the use of methanol (less lignin must be kept in solution) and acid (less acid which buffers the pH-decrease) become much lower. The present invention also provides according to a second aspect a polymeric pentose product or an intermediate polymeric pentose product obtainable by the method according to the first aspect. The present invention also provides according to a third aspect use, preferably for the production of food additives or as chemical feed stock, of the polymeric pentose product or the intermediate polymeric pentose product of the second aspect of the invention.
摘要翻译：本发明提供了从含聚合戊糖的液体/浆液（优选黑液）中提取聚合戊糖，优选木聚糖的方法，包括以下步骤：a）提供含有聚合物的含有戊糖的液体/浆液; b）通过膜分离所述含聚合戊糖的液体/浆液来浓缩聚合戊糖; 和c）向步骤b）中获得的浓缩物中加入醇，然后酸化步骤b）中获得的浓缩物，以沉淀聚合戊糖，由此得到聚合戊糖产物或中间聚合戊糖产物。以上述方式，聚合戊糖，例如木聚糖被分离，由此使用甲醇（较少的木质素必须保持在溶液中）和酸（较少酸，缓冲pH降低）变得低得多。本发明还提供根据第二方面的聚合物戊糖产物或通过根据第一方面的方法可获得的中间聚合戊糖产物。本发明还提供了根据第三方面的用途，优选用于生产本发明第二方面的聚合戊糖产物或中间聚合戊糖产品的食品添加剂或化学原料。
