摘要:Starch granules were prepared from seeds of Amaranthus hypochondriacus L., A. caudatus L., proso millet, Japanese barnyard millet and foxtail millet. Amylose contents and the distribution of α-l, 4 linked chain of amylopectin were determined by gel filtration of isoamylasedebranched starches. Some physical and chemical properties of the starches were also examined by scanning electron microscopy, X-ray diffractometry, photopastegraphy, and differential scanning calorimetry, together with starch-granule susceptibility to amylases. The existence of both normal and waxy types in the same species of a grain amaranth, A. hypochondriacus L., was confirmed. A. caudatus starches were identified to consist of mainly typical amylopectin and 5-7% amylose. The starches have some unique properties, namely, high starch-granule susceptibility values to amylases as well as those of A. hypochondriacus and unique pasting properties.
