Abstract
Starch hydrolyzates having a desired degree of polymerization are prepared by hydrolyzing derivatized starch esters with amylase and thereafter saponifying the starch ester hydrolyzates to obtain a hydrolyzate product essentially free from substitution. Amylolysis and saccharide distribution of the resultant saponified hydrolyzates are effectively accomplished by pre-selecting a starch ester having the appropriate degree of ester substitution.
