ABSTRACT:
A process comprising dissolving a pyrodextrin in water, hydrolyzing the solution with alpha-amylase at a low temperature to obtain a hydrolyzate of reduced viscosity, further hydrolyzing the hydrolyzate to an intermediate extent at a high temperature, autoclaving the resulting hydrolyzate, finally hydrolyzing the hydrolyzate with alpha-amylase again after cooling, and autoclaving the final hydrolyzate again. Pyrodextrin hydrolyzate can be prepared without impairing the inherent characteristics of pyrodextrin.
