  In one aspect, the present invention provides a method for preparing a sugar composition. The method includes: forming a mixture including polysaccharide biomass and an ionic liquid solution, wherein the ionic liquid solution contains water and an ionic liquid, and wherein the ionic liquid contains a dicarboxylic acid anion and a cation. The pH of the mixture is greater than or equal to about 10, and the molar ratio of the dicarboxylic acid anion to the cation is at least about 1:2. The method further includes: maintaining the mixture under conditions sufficient to dissolve at least a portion of the polysaccharide present in the polysaccharide biomass; reducing the pH of the mixture containing the dissolved polysaccharide to at least about 7; adding at least one glycoside hydrolase to the mixture having the reduced pH.

  一方面，本发明提供了一种制备糖组合物的方法。该方法包括：形成包括多糖生物质和离子液体溶液的混合物，其中离子液体溶液包含水和离子液体，离子液体包含二羧酸阴离子和阳离子。混合物的 pH 值大于或等于约 10，二羧酸阴离子与阳离子的摩尔比至少约为 1:2。该方法进一步包括：将混合物保持在足以溶解多糖生物质中存在的至少一部分多糖的条件下；将含有溶解多糖的混合物的pH值降低到至少约7；向pH值降低的混合物中加入至少一种糖苷水解酶。
