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.
Claims23
A method of preparation for psicose comprising:
- separating psicose conversion product with a simulated moving bed (SMB) chromatography 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.
The method of preparation of claim 1, wherein the method further comprises a step of ion purification of the fructose raffinate, before, after, and before and after the SMP chromatography separation process.
An apparatus of preparation for a psicose by performing a biological psicose conversion process using a fructose-containing raw material comprising:
- a psicose conversion reactor for performing psicose conversion reaction from fructose-containing raw material using a biological catalyst,
- a simulated moving bed (SMB) chromatography separator which comprises a column packed with cation exchange resin having an active group, a feed inlet and an outlet for discharging a psicose fraction and a fructose raffinate, and
- an ion purifier equipped with a column packed with ion exchange resin and a concentrator, which the fructose raffinate discharged from the chromatography separator passes through and recycled into the psicose conversion reactor.
