摘要：
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.本文中揭露一種D-阿洛酮糖的製造方法。所述D-阿洛酮糖的製造方法包含使D-果糖經受D-阿洛酮糖表異構化以產生含D-阿洛酮糖的溶液，使所述含D-阿洛酮糖的溶液經受第一冷卻及離子純化，使經純化的含D-阿洛酮糖的溶液經受第一濃縮及第二冷卻，使已經受第一濃縮及第二冷卻之含D-阿洛酮糖的溶液經受層析以獲得含D-果糖的母液及含D-阿洛酮糖的分離溶液；以及使所述含D-阿洛酮糖的分離溶液經受第二濃縮及第三冷卻以獲得D-阿洛酮糖晶體，其中在所述D-阿洛酮糖表異構化中再使用由層析產生之含D-果糖的母液。
