ABSTRACT:
A process for the degradation of granular starch employing hydrogen peroxide and a catalytic amount of manganese ions in an alkaline slurry reaction is disclosed. The manganese ions catalyze the degradative reaction so that the desired amount of degradation of the granular starch can be brought about in a shorter reaction period as opposed to a reaction run without manganese ions.
