    • A method for hydrolyzing coffee extraction residue materials to produce manno-saccharides having a degree of polymerization from 1 to 10 and subsequently neutralizing and reducing said mixture of manno-saccharides to their corresponding alcohols. The coffee material, preferably spent coffee grounds from a commercial percolation system, is hydrolyzed in a Plug Flow tubular reactor in the presence of an acid catalyst, such as sulfuric acid. Depending on the time, temperature, pressure and catalyst concentration selected, manno-saccharides or mannose is produced. The manno-saccharides or mannose produced are separated from coffee residue material in the form of a syrup and neutralized with calcium hydroxide. The neutralized mixture of manno-saccharides or mannose is reduced to their corresponding alcohols or mannitol.
    • 一种水解咖啡提取残渣物质以产生1至10聚合度的甘露糖并随后中和并将所述人造血糖混合物还原成其相应的醇的方法。 咖啡材料,优选来自商业渗滤系统的消耗咖啡渣,在硫酸催化剂存在下在Plug Flow管式反应器中水解。 根据所选择的时间,温度,压力和催化剂浓度,产生甘露糖或甘露糖。 将生成的甘露糖或甘露糖与糖浆形式的咖啡残余物质分离,并用氢氧化钙中和。 中和的人造血糖或甘露糖的混合物被还原成其相应的醇或甘露糖醇。
