ABSTRACT=IntroductionAlisma starch (AS) from Alismatis Rhizoma has potential applications but has been less studied compared to common starches like corn starch (CS) and potato starch (PS).MethodsWe used scanning electron microscopy, X-ray diffraction, and rapid visco analysis to study the granule morphology, crystal structure, pasting properties, freeze -thaw stability, solubility, swelling degree, and gel strength of AS, CS, and PS.ResultsAS has a lower starch content but higher amylose content than CS and PS. It has a smaller particle size and is A-type starch. Its pasting temperature and trough viscosity are higher, and its freeze -thaw stability is intermediate. Gel strength increases with concentration and shows no significant difference between 10% AS and 12% PS.DiscussionAS has good heat resistance, shear resistance, and gel strength, indicating potential for high-temperature processed foods. Future research should focus on its heat resistance mechanism and broader applications.
