    Abstract: PROBLEM TO BE SOLVED: To provide a highly concentrated solid enzyme formulation containing only the enzyme and a stabilization support.SOLUTION: The solid enzyme formulation contains: (a) at least one particulate enzyme composition composed of at least one enzyme and at least one monovalent or divalent cationic organic or inorganic salt; (b) at least one particulate organic or inorganic support; and (c) at least one hydrophobic liquid mixture. The process for preparation of the solid formulations includes following steps of: spray drying or by spray drying and agglomeration of at least one enzyme-containing liquid. The enzyme composition contains an enzyme component selected the group consisting of xylanases, glucanases, and mixtures thereof wherein the enzyme component is present in a mixture with magnesium sulfate, wherein the magnesium sulfate fraction is present in a range of from about 5 to about 25 wt.%, based on the total weight of the dry enzyme composition. Obtained enzyme composition is mixed with the particulate inorganic or organic support. The enzyme/support mixuture is wetted with a hydrophobic liquid.

    Abstract translation: 要解决的问题：提供仅含有酶和稳定支持物的高度浓缩的固体酶制剂。 固体酶制剂含有：（a）由至少一种酶和至少一种一价或二价阳离子有机或无机盐组成的至少一种微粒酶组合物; （b）至少一种颗粒状有机或无机载体; 和（c）至少一种疏水性液体混合物。 制备固体制剂的方法包括以下步骤：喷雾干燥或通过喷雾干燥和至少一种含酶液体的附聚。 酶组合物含有选自由木聚糖酶，葡聚糖酶及其混合物组成的组的酶组分，其中酶组分与硫酸镁存在于混合物中，其中硫酸镁级分的存在量为约5至约25重量％ ％，基于干酶组合物的总重量。 获得的酶组合物与颗粒状无机或有机载体混合。 酶/载体混合物用疏水液体润湿。 版权所有（C）2012，JPO＆INPIT
