Obvious birefringences can be observed and most of them are showed in shape stretching along the long axis. The range of starch granule size is 8 to 30 μm with mean granules diameter 22μm. Arrowroot starch is attributed to A-type crystal structure and the degree of crystallinity is 36.1%. The gelatinization temperature is 72.7 ℃.
