Abstract: The properties of cross-linked esterification of sweet potato starch were studied with differential scanning calorimetry (DSC), scanning electron micrographs(SEM), and X - ray diffraction. The results showed that the gelatinization characteristic, granular shapes and X-ray diffraction patterns of modified sweet potato starches were clearly different from those of native sweet potato starch. The mechanism of modified granular sweet potato starch conversion was discussed.

Key words: cross-linked sweet potato starch esters, properties
