Abstract：
:An efficient method was developed to prepare oxidized potato starch under the pasting point by Electro-Fenton system, in which a complex of sodium citrate and Fe2+ (SC-Fe2+) was used as catalyst, and H2O2 was used as oxidant. In the preparation process the oxidation degree of starch was controlled by the molar ratios of SC-Fe2+ and hydrogen peroxide. The structures and thermal properties of the prepared oxidized starch were characterized by FT-IR, XRD, SEM, DSC and DTG. The characterization results indicated that the obtained oxidized potato starch owned one grainy molecule structure, and displayed a high viscosity (not less than 63 Pa·s) by comparing to the raw starch. The carbonyl and carboxyl contents of oxidized potato starch achieved 0.81 per 100 AGU and 0.79 per 100 AGU, respectively after the raw starch was oxidized. And the oxidized starch showed good thermal stability, which can dramatically improve the application performance of starch-based biomaterials.
