A method to control the distribution of the starch sugar's molecular weight by controlling of Ultra-low DE value during the reaction was invented. The meth od comprising blending starch with water to get starch slurry and then mixing i t with the 0.01%- 0.03% of CaCl2 based on dried starch. The next step involves adjustin g the pH of the starch slurry. A further step involves adding 0.03% - 0.08% of heat- resisting .alpha.- amylases based on dried starch to the starch slurry described above. A furth er step involves controlling the production under optimal reaction conditions.</SDOA B>
