ABSTRACT:
A method is disclosed for softening and purifying molasses or syrup to obtain a clarified syrup that can then easily be handled by conventional ion-exclusion or other techniques for recovery of sugar. The process comprises steps that can be performed at ambient temperature. The molasses or syrup is carbonated at high pH, followed by adding organic solvent(s) such as ethanol. The sludge and liquid phases are separated. The solvent is then recovered, leaving a liquid phase comprising a soft and very clear sugar-containing liquid. The liquid phase may then be used in known systems for sugar recovery such as ion-exclusion chromatographic systems. Organic acids such as aconitic acid may be recovered from the sludge residue.
