1. utilize simulation moving-bed new technology to prepare a method for high purity trehalulose liquid, it is characterized in that:

  • with the solution containing trehalulose and Palatinose component for raw material, its processing step is as follows;

    Raw material, through dilution, decolouring removal of impurities, then, again separation and purification refining from friendship, finally concentrates and obtains high purity trehalulose liquid product;

    Described dilution is for be diluted to 40 ~ 60 °

    of Bx with pure water by raw material;

    Described decolouring removal of impurities, for adding gac by raw materials quality than 0.5% ~ 5.0%, is heated to 45 DEG C ~ 60 DEG C, 30 ~ 60 minutes under agitation, filters, gets filtrate;

    Described from friendship purification step be filtrate by ion exchange resin, electrical conductivity of solution is down to below 20us/cm;

    Described purification procedures be solution by simulation moving-bed separation, make the content of trehalulose by 30 ~ 50%, bring up to 60 ~ 80%;

    Described simulation moving-bed be that 6 ~ 24 root chromatogram columns head and the tail orders are connected, fill separating agent, control charging by central control unit, water inlet, trehalulose liquid bring out mouth and Palatinose brings out the flow of mouth four ports;

    Described enrichment step be the mode of the trehalulose liquid after separation and purification by vacuum concentration by brix by 10 ~ 30 °

    of Bx, bring up to 70 °

    of more than Bx.
