Objective] To reveal the effects of surface proteins and lipids on hydrolysis dynamics of rice starch.[Method] The surface pro-teins and lipids were removed from starch granules using the sodium dodecyl sulfate.The starch was hydrolyzed byα-amylase and amylogluco-sidase.The starch hydrolysis was measured.[ Result] The surface proteins and lipids decreased the hydrolysis rate.The effect was not con-spicuous in waxy starch, but was conspicuous in starch with high amylose content.[ Conclusion] The surface proteins and lipids have certain impacts on the hydrolysis of starch.
