Abstract: The physiochemical characteristics of LiPu Taro amylum were studied from these respects: particle shape, particle size, the ratio of amylase to amylopectin, viscosity, dextrinizing temperature, and so on. Then, A set of parameters of LiPu Taro amylum were got. The particle shape was unregular and polygon. The range of the lateral diameter was 5.50～11.20μm with the average 8.60μm; and the longitudinal diameter 4.60～9.80μm with the average 7.63μm. The amylum was constituted by single glucose and the ratio of the amylase to amylum was 10.5%. The dextrinizing temperature was 92℃.

Key words: LiPu Taro, amylum, physichemical characteristic
