    • The invention concerns a process for the preparation of a sorbitol rich syrup having less than 0.2% on ds of total reducing sugars, wherein said process comprises the following steps: (i) hydrogenation of a glucose syrup having a glucose content of 94% to 97% on dry substance (d.s.), (ii) separation step of the hydrogenated glucose syrup by at least one membrane nanofiltration stage to obtain a permeate and a retentate, wherein the permeate is a sorbitol rich syrup having at least 99.2% by weight on ds of hexitol, less than 0.2% by weight on ds of total reducing sugars and less than 0.3% by weight on ds of sugar alcohols having a molecular mass higher than hexitols. The invention also concerns a sorbitol rich syrup having at least 99.2% by weight on ds of hexitol, less than 0.1% by weight of total reducing sugars on ds and less than 0.2% by weight on ds of sugar alcohols having a molecular mass higher than hexitols.
    • 本发明涉及一种制备富含山梨糖醇糖浆的方法,该糖浆的总还原糖含量小于0.2%,其中所述方法包括以下步骤:(i)将葡萄糖含量为94%至97的葡萄糖浆氢化 在干物质(ds)上的%,(ii)通过至少一个膜纳米过滤阶段的氢化葡萄糖浆的分离步骤以获得渗透物和渗余物,其中所述渗透物是富含山梨糖醇的糖浆,其在ds上具有至少99.2重量% 的己糖醇,小于总重量为ds的0.2重量%,并且具有小于分子量高于己醇的糖醇的0.3重量%。 本发明还涉及一种富含山梨糖醇的糖浆,其在己糖醇的ds上具有至少99.2重量%的糖,小于ds的总还原糖的0.1重量%,分子量高于蔗糖的糖醇小于0.2重量% 己糖醇。
