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.
