    • A method for selective hydrolysis of the hemicellulose component of a biomass material. The selective hydrolysis produces water-soluble small molecules, particularly monosaccharides. One embodiment includes solubilizing at least a portion of the hemicellulose and subsequently hydrolyzing the solubilized hemicellulose to produce at least one monosaccharide. A second embodiment includes solubilizing at least a portion of the hemicellulose and subsequently enzymatically hydrolyzing the solubilized hemicellulose to produce at least one monosaccharide. A third embodiment includes solubilizing at least a portion of the hemicellulose by heating the biomass material to greater than 110°C resulting in an aqueous portion that includes the solubilized hemicellulose and a water insoluble solids portion and subsequently separating the aqueous portion from the water insoluble solids portion. A fourth embodiment is a method for making a composition that includes cellulose, at least one protein and less than about 30 weight% hemicellulose, the method including solubilizing at least a portion of hemicellulose present in a biomass material that also includes cellulose and at least one protein and subsequently separating the solubilized hemicellulose from the cellulose and at least one protein.
    • 选择性水解生物量材料的半纤维素成分的方法。 选择性水解产生水溶性小分子,特别是单糖。 一个实施方案包括溶解半纤维素的至少一部分,随后水解溶解的半纤维素以产生至少一种单糖。 第二个实施方案包括溶解半纤维素的至少一部分,随后酶促水解半纤维素以产生至少一种单糖。 第三个实施方案包括通过将生物质材料加热至大于110℃来增溶半纤维素的至少一部分,从而得到包含溶解的半纤维素和水不溶性固体部分的水性部分,随后将水部分与水不溶性固体分离 一部分。 第四个实施方案是制备包含纤维素,至少一种蛋白质和小于约30重量%半纤维素的组合物的方法,所述方法包括溶解存在于生物质材料中的至少一部分半纤维素,所述生物质材料还包括纤维素和至少一种 蛋白质并随后从纤维素和至少一种蛋白质中分离溶解的半纤维素。
