摘要: 为了对魔芋淀粉进一步开发利用提供理论依据,本实验对魔芋淀粉的透明度、老化度、可溶率和膨胀度、直链淀粉和支链淀粉含量、冻融稳定性等理化性质进行研究。结果表明,魔芋淀粉中支链淀粉的含量均高于马铃薯和玉米,其透明度、可溶率、老化值及冻融稳定性均优于马铃薯和玉米淀粉,是一种品质优良的食用淀粉。

Abstract: In order to provide a theoretical basis for development and utilization of konjac starch, some physical and chemical properties of konjac starch were analyzed in this study, including transparency, solubility, retro-gradation value, swelling power, amyloes and amylopectin contents and freeze-thaw stability. The results indicated that the content of amylopectin in konjac starch is higher than that of potato starch or maize starch. The transparency, solubility, retro-gradation value and freeze-thaw stability are superior to those of potato starch or maize starch. So konjac starch is a high-quality food starch.
