Procedure

Maltitol/lactitol liquid feed solutions were prepared by dissolving crystalline maltitol (C*Maltidex CH16385 produced by Cerestar, Krefeld, Germany; maltitol purity 99.7% on DS) into an aqueous lactitol solution produced by dissolving crystalline lactitol (Lactitol CM 50 produced by Xyrofin Oy, Kotka, Finland) to a total concentration of 67-73% on DS. The ratio of maltitol to lactitol was 1:1 by weight. The feed solution was heated to a temperature of 55-75° C. and filtered.
