Abstract
The invention relates to a process for purifying syrups. The process comprises removing charged components from the syrup by passing said syrup through a capacitive deionization cell. The present invention further relates to the use of capacitive deionization to recover charged components from syrups. In particular the syrups are mannose, fructose and sorbitol containing syrups.
Claims20
A process to remove charged components from a syrup comprising:
- passing the syrup through a capacitive deionization cell, wherein the specific surface area of the capacitive deionization cell is in the range of 600 to 1100 m2/g and the flow rate of syrup through the capacitive deionization cell is from 50 to 100 l/h, and
- performing a regeneration step comprising releasing charged components from the capacitive deionization cell into a portion of the syrup by inverting the electrode charge of the capacitive deionization cell to form a syrup enriched in charged components, and
- draining the syrup enriched in charged components from the capacitive deionization cell.
A process to remove and recycle charged components from a syrup comprising:
- passing a syrup through a capacitive deionization cell to remove charged components to form a purified syrup;
- performing a regeneration step comprising releasing charged components from the capacitive deionization cell into a portion of the syrup by inverting the electrode charge of the capacitive deionization cell to form a syrup enriched in charged components;
- draining the syrup enriched in charged components from the capacitive deionization cell;
- and
- recycling the charged components by reusing the syrup enriched in charged components in a process for catalytic reaction of a sweetener.
