Hydrolyzed starches were analyzed for the degree of hydrolysis and for physicochemical and functional properties. Corn starch showed the highest degree of hydrolysis, as evidenced by the presence
of distinct pores penetrating deep into the granules. Enzymatic erosion occurred mainly at the surface for cassava,
whereas isolated porous structures were observed in hydrolyzed mung bean and sago starch. The amylose content
was significantly lower in all starches except for sago starch. The powder X-ray diffraction of all starches showed no
significant changes after hydrolysis, but hydrolyzed starches showed a more crystalline nature. The action of enzymes
caused significant changes in some pasting properties and in the swelling/solubility of starches. Evidently, enzymes
were able to hydrolyze granular starches to a variable degree at sub-gelatinization temperature, and produced a
relatively high degree of conversion
