ABSTRACT:
Process for converting starch to dextrose wherein a partially hydrolyzed starch solution containing at least 10 percent hydrolyzed starch is contacted with an enzyme system under conditions whereby substantially complete conversion of the starch to dextrose is achieved. The enzyme system comprises immobilized glucoamylase and alpha-amylase selected from the group consisting of soluble alpha-amylase, immobilized alpha-amylase and mixtures thereof.
