ABSTRACT:
A multi-step process is provided for solubilizing and saccharifying granular starch slurries of between 20 and 60% d.s. starch. In a first step, an enzyme mixture exhibiting raw starch hydrolyzing activity is added to the slurry and maintained in contact therewith until at least a substantial portion but less than all of the starch is solubilized. The resulting syrup is separated from the remaining insoluble fraction. In a second step, the insoluble fraction is used to prepare a second slurry containing less than about 20% d.s. starch, and this second slurry is solubilized with a raw starch hydrolyzing enzyme preparation until substantially all (e.g., at least about 95% or more) of the starch is solubilized. The pooled syrup from the two steps is over about 20 weight percent saccharides, at least about 95% of which is glucose.
