高纯度D-阿洛酮糖的制造方法
摘要：
本文中揭示一种D-阿洛酮糖的制造方法。所述D-阿洛酮糖的制造方法包含使D-果糖通过D-阿洛酮糖表异构化以产生含D-阿洛酮糖的溶液，使所述含D-阿洛酮糖的溶液通过第一冷却及离子纯化，使经纯化的含D-阿洛酮糖的溶液通过第一浓缩及第二冷却，使已通过第一浓缩及第二冷却的含D-阿洛酮糖的溶液通过层析以获得含D-果糖的母液及含D-阿洛酮糖的分离溶液；以及使所述含D-阿洛酮糖的分离溶液通过第二浓缩及第三冷却以获得D-阿洛酮糖晶体，其中在所述D-阿洛酮糖表异构化中再使用由层析产生的含D-果糖的母液。
摘要（英）：

Disclosed herein is a method of producing D-psicose. The method of producing D-psicose includes subjecting D-fructose to D-psicose epimerization to produce a D-psicose-containing solution, subjecting the D-psicose-containing solution to first cooling and ion purification, subjecting the purified D-psicose-containing solution to first concentration and second cooling, subjecting the D-psicose-containing solution, which has been subjected to first concentration and second cooling, to chromatography to obtain a D-fructose-containing mother liquor and a D-psicose-containing separated solution, and subjecting the D-psicose-containing separated solution to second concentration and third cooling to obtain D-psicose crystals, wherein the D-fructose-containing mother liquor produced by chromatography is reused in the D-psicose epimerization.
