Enzymic conversion, of starch

D-Glucose can also be obtained by enzymic conversion of starch or cellulose. Two separate enzymic processes, liquefaction and saccharification, are generally used in the production of D-glucose from starch. The liquefaction process solubilizes the molecules in the starch granules and decreases the viscosity of the starch. In the saccharification step, the liquefied starch is further hydrolyzed to D-glucose by the action of glucoamylase. The majority of starches used for the manufacture of D-glucose contain up to 80% amylopectin 99...
