Abstract:
    The present invention relates to The present invention relates to a method for preparing degradable material by deep-processing corn. Said method includes the following steps: (1), coarse-pulverizing corn, and making the coarse-pulverized corn be suspended in the water, adding butanedioic anhydride derivative, using metal alkaline solution to regulate pH value to 9-12, heating to 65-80deg.C and making reaction for 6-10hr; (2), adding cross-linking agent into emulsion, reacting for 0.1-5hr, then adding acid to make neutralization and regulate pH value to 5.5-6.5, heating said system to 80-100deg.C, heat-insulating for 25-50min, filtering and water-washing to normal temperature; and (3), adding alpha-amylase, making biological degradation, finally, filtering hydrolysate, drying and pulverizing so as to obtain starch degradable material.
