Title:
METHOD OF PRODUCING HIGH PURITY D-PSICOSE
Document Type and Number:
WIPO Patent Application WO/2017/150766
Kind Code:
A1
Abstract:
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.
