Abstract: In order to provide a theoretical basis for development and utilization of konjac starch, some physical and chemical properties of konjac starch were analyzed in this study, including transparency, solubility, retro-gradation value, swelling power, amyloes and amylopectin contents and freeze-thaw stability. The results indicated that the content of amylopectin in konjac starch is higher than that of potato starch or maize starch. The transparency, solubility, retro-gradation value and freeze-thaw stability are superior to those of potato starch or maize starch. So konjac starch is a high-quality food starch.

Key words: konjac, starch, physical and chemical properties
