ABSTRACT:
Inorganic oxy-acid and organic acid impurities are removed from raw cane sugar or molasses solutions by the steps of (1) admixing with the raw cane sugar syrup or molasses solution a water-soluble chloride of an alkaline earth metal ion which reacts with inorganic oxy-acid anions and radicals and with organic acids to form a water-insoluble precipitate of said oxy-acid anions and radicals and organic acids, (2) separating said precipitate from said solution while maintaining the Brix degree of the solution between more than 60% and less than 80%, (3) diluting the precipitate-free solution to a Brix of less than 55%, and (4) subjecting said diluted solution to an electrodialysis using cation exchange film and neutral film arranged in an alternating manner.
