ABSTRACT:
High-purity maltose is produced by applying a feed starch sugar solution with a maltose content of at least 70% to a column packed with a strongly-acidic cation exchange resin of alkali metal- or alkaline earth metal-form; fractionating the feed solution by charging water thereto into a high-dextrin fraction, a high-dextrin.maltose fraction, a high-maltose fraction, a high-maltose.glucose fraction, and a high-glucose fraction, in the given order; and recovering the high-maltose fraction. This process constantly provides a fraction with a maltose content of 93% or higher, and enables industrial-scale production of a high-purity maltose much easier and at lower-cost than conventional processes.
