Abstract:
1. A method for purifying a high purity sucrose material, the method comprising: degassing a stream comprising a high purity sucrose material; dissolving said high purity sucrose material in an eluent; feeding said stream to a chromatographic process in a system comprising one or more chromatographic columns or beds, said chromatography process being selected from the group consisting of batch chromatography, simulated moving bed, continuous simulated moving bed, semi-continuous simulated moving bed, time variable simulated moving bed, sequential simulated moving bed and combinations of any thereof; and producing at least a first product stream and a second product stream from said chromatographic process, wherein said first product stream comprises a higher concentration of said sucrose material on a dry solids basis than said stream comprising said high purity sucrose material and a higher concentration of said sucrose material on a dry solids basis than said second product stream, and wherein said second product stream comprises a higher concentration of one or more non-sucrose components than said first product stream.
