    摘要: A method of preparing modified cellulose pulp using arabinoxyolans is described. The method involves contacting, (i) an arabinoxylan with (ii) a cellulose pulp. The arabinoxylan of the process is in a form selected from a concentrated solution comprising arabinoxylan or a suspension comprising arabinoxylan. Also described are: a modified cellulose pulp prepared according to the present invention; and a particular arabinoxylan having on its main chain 5 to 20% arabinose substituents, and less than 5% 4-O-methylglucuronic acid substituents, (the percent weights being based on the total weight of the arabinoxylan).
