摘要: 本文从荔浦芋淀粉颗粒的形态大小及淀粉中直链与支链淀粉的比例,淀粉的粘度和糊化温度等方面研究了荔浦芋淀粉的理化性质。从而得到一系列荔浦芋淀粉性质的参数:淀粉颗粒形状为无规则多边形,横径范围为5.5~11.2μm,平均为8.60μm,纵径范围4.6~9.8μm,平均为7.63μm,淀粉是由单一葡萄糖组成,其直链淀粉含量约为总淀粉的10.5%。其糊化温度为92℃。

Abstract: The physiochemical characteristics of LiPu Taro amylum were studied from these respects: particle shape, particle size, the ratio of amylase to amylopectin, viscosity, dextrinizing temperature, and so on. Then, A set of parameters of LiPu Taro amylum were got. The particle shape was unregular and polygon. The range of the lateral diameter was 5.50~11.20μm with the average 8.60μm; and the longitudinal diameter 4.60~9.80μm with the average 7.63μm. The amylum was constituted by single glucose and the ratio of the amylase to amylum was 10.5%. The dextrinizing temperature was 92℃.
