Abstract
The present invention relates to a method for effectively utilizing fructose raffinate obtained in the process for separating psicose conversion product with a high purity chromatography in the process for preparing psicose, and more specifically, it is utilized for preparation of fructose-containing raw material solution for preparing psicose by supplying the fructose raffinate obtained in the separation step of psicose preparation into the psicose conversion reaction.
Claims16
A method of preparation for psicose comprising:
- separating psicose conversion product of a psicose conversion reaction with a simulated moving bed (SMB) chromatography separation process to obtain a psicose fraction and a fructose raffinate, and recycling the fructose raffinate as a first fructose raw material into the psicose conversion reaction, mixing the fructose raffinate with a fresh fructose raw material as a second fructose raw material, before being recycled to the psicose conversion reaction, wherein a mixing ratio of the fructose raffinate and the second fructose raw material (raffinate:second fructose raw material) is a volume ratio of 1:0.9 to 1.5, when the fructose raffinate and the second fructose raw material have 50 Brix.
