title: Physicochemical properties of rhizome starch from a traditional Chinese medicinal plant of Anemone altaica.
abstract: This study investigated the physicochemical properties of rhizome starch of A. altaica for the first time. The results were compared to those obtained from two common starches (potato and rice). The rhizome had a starch content of 49.8%. Isolated starch granules were mostly oval in shape with a central Maltese cross and an average long axis of 6.25 μm. The starch contained 35.5% amylose and had lower gelatinization and pasting temperatures than rice and potato starches and a swelling power comparable to potato. Altaica starch had high breakdown and setback viscosities. X-ray diffraction revealed B-type starch with relative degree of crystallinity of 17.5%. Starch possessed a high susceptibility to hydrolysis by acid, porcine pancreatic α-amylase and Aspergillus niger amyloglucosidase when compared with potato and rice starches.
