  • Patent number: 4281028
    Abstract: Sweet, non-crystallizing (at concentrations of 75% solids or above) syrups are prepared having the following saccharide composition: dextrose, from 20% to 40%; levulose, from 20% to 40%; maltulose, from 10% to 60%; total ketose composition (principally levulose and maltulose), 40% to 80% (percentages by weight dry basis). Optionally, the syrups may contain up to 25% maltose and/or up to 20% higher saccharides (i.e. having degrees of polymerization of greater than 2). The syrups are prepared by first subjecting a starch hydrolyzate, containing at least 40% maltose and not more than 5% dextrose, to an alkaline isomerization treatment to isomerize a portion of the maltose to maltulose, the isomerization being conducted until the resulting hydrolyzate contains between 10% and 60% maltulose. The resulting product is then treated with a glucoamylase to saccharify at least a portion of the remaining maltose (as well as higher saccharides, if present) to dextrose.
