摘要:  研究测定竹芋淀粉颗粒、糊及其凝胶等特性。发现竹芋淀粉颗粒多呈卵形和椭圆形,直径约8~30μm,平均直径为22μm,大颗粒表面有明显的轮纹。竹芋淀粉颗粒的轮纹及偏光十字明亮清晰、淀粉颗粒表面呈明显的偏光十字,形状不规则、有相当部分呈垂直十字、若干呈斜十字和X形。X-衍射呈A型结晶图样,结晶度为36.1%,糊化温度为58.2℃。

Abstract: The granules,paste,gel and other properties of arrowroot starch were studied. Most of the granules are of olivary and ellipse shap. The surface of big granules have obvious wheel stripes. 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 ℃.
