Abstract: A method for producing high purity D-psicose crystals having a purity of 98% (w/w) or more and a grain size of MA200 or more. The method includes: removing impurities from a D-psicose solution to obtain a purified D-psicose solution; concentrating the purified D-psicose solution; cooling the concentrated D-psicose solution to 30° C. to 40° C. through a heat exchanger; seed crystallizing the D-psicose solution at 30° C. to 40° C. to obtain a seed crystallized massecuite; and full-scale crystallizing the seed crystallized massecuite. The method can produce pure D-psicose crystals in a suitable form for industrial application through an economical crystallization process from the D-psicose solution without using organic solvents.

Abstract: The present application relates to improving the production yield of glucose to be prepared by using starch sugar as a raw material and using an Acidothermus sp. derived enzyme. The present application can replace an acid saccharification method, which produces a bitter taste through a hydrolysis reverse reaction, and, compared to a enzymatic saccharification method in which a conventional debranching enzyme is used, has an advantage of enabling costs to be reduced since a relatively high yield can be ensured by reducing side reactions of a saccharification reaction.

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.
