ABSTRACT:
A lactulose syrup suitable for use in the production of foods and drugs is produced by the alkali isomerization of lactose. Elimination of monosaccharides formed in the reaction mixture, such as galactose, is conducted by passing the reaction mixture through a column packed with beads of a strongly-acidic chromatographic cation-exchange resin, said beads having substantially the same crosslinking degree, and then collecting lactulose-containing eluate fractions. This process is suitable for the industrial production of a high-purity lactulose syrup.
