Abstract: The structure properties of the adzuki bean starch have been studied. The range of starch granule size is 18～80μmand its mean granules diameter is 40.8μm. Obvious birefringence been observed. Adzuki bean starch is attributed to A-type crystalstructure and its degree of crystallinity is 40.5%. The compound of adzuki bean starch with I2 has the maximal absorbance at the618nm and its amylose content is 33.2%. The swelling ability and solubility of the adzuki bean starch is better than maize butnot like that of cassava. Adzuki bean starch paste belongs to pseudoplastic fluid. The shear resistance and the setback capacityare stronger than maize and cassava. Adzuki bean starch has good hot and cold paste stability. Its monoglyceride has specific impacton adzuki bean starch paste.
