ABSTRACT:
Saccharification of 10-20% solid content dextrin solutions for 15-75 hours at amyloglucosidase enzyme dosage levels of 0.3-1.0 AG u/g of solids results in glucose syrups with purity levels exceeding 98%.
Glucose purity levels in excess of 98.5% can be achieved if the dextrin solution is formed by enzymatic liquefaction of starch, and saccharification is carried out for 15-25 hours with 0.4-0.8 AG u/g.
