Abstract
A method for separating sucrose and a second dissolved component from a sucrose-containing solution, preferably a beet-derived sucrose-containing solution, wherein the solution is subjected to a first fractionation by a continuous or sequential chromatographic simulated moving bed process to yield a sucrose-enriched fraction and a fraction enriched with the second dissolved component. The resulting fraction enriched with the second component is subjected to a second chromatographic fractionation that is a simulated moving bed or batch type process, to yield a second sucrose-enriched fraction and a second fraction enriched with the second dissolved component wherein both fractions have an improved yield or purity.
