Abstract
The present invention provides a process for production of starch sugars, wherein starch is subjected to liquefaction and saccharification to prepare a mixture containing 10-50% by weight, based on the total solid content, of glucose and 30-50% by weight, also based on the total solid content, of maltose and the mixture is concentrated so as to have a total solid content of 40-70% by weight; and the resulting mixture is subjected to component separation using a chromatographic separator of simulated moving bed type capable of fractionating the mixture into at least three fractions, to produce a glucose fraction with a glucose purity of at least 97% by weight, a maltose fraction with a maltose purity of at least 80% by weight and a high-purity oligosaccharide fraction at a high efficiency in one operation. In the process, no strict control is required for the enzymatic reactions taking place in the liquefaction and saccharification of starch, and all the fractions obtained by the chromatographic fractionation can be made into marketable products.
