Claims37
A method for purifying a high purity sucrose material, the method comprising:
- degassing a stream comprising a high purity sucrose material feeding said stream to a chromatographic process in a system comprising one or more chromatographic columns or beds;
- 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 on a dry solids basis than said stream comprising said high purity sucrose material and a higher concentration of said sucrose 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.
A method for purifying a high purity sucrose material, the method comprising:
- feeding a stream comprising a high purity sucrose material to a chromatographic process in a system comprising one or more chromatographic columns or beds;
- 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 on a dry solids basis than said stream comprising said high purity sucrose material and a higher concentration of said sucrose 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
- wherein said high purity sucrose material is selected from the group consisting of:
- turbinado sugar, demerara sugar, muscovada sugar, brown sugar, and combinations of any thereof.
