Abstract: This paper studied the characteristics of Arenga pinnota starch, about granular sizes, the ratio of amylose toamylopectin, viscosity and gelation temperature. It revealed a series of physical and chemical characteristics of this starch. Thevertical diameter of the grain ranged from 15μm to75μm and the average was 25μm. The horizontal diameter ranged from5μm to 35μm and the average was 14.17μm. The amylose content of total starch was 62.24%. It became paste at 68℃.

Key words: Arenga pinnota starch, characteristics
