In order to prove up the interaction between konjac glucomannan （KGM） and other amyloses, by using KGM, guaran gum and carrageenan as materials, their blending in different external conditions was modeled by means of molecular dynamics （MD） method.The result showed that 323 K was a significant turning point for the formation of hydrogen bond, and KGM and guaran gum were just juxtaposed together via intermolecular hydrogen bond; but with the addition of carrageenan, KGM, guaran gum and carrageenan were spirally twisted together, and when their blending proportion is 3：2：9 the combination was the most compact. Moreover, the research result has provided the sequent studies afterwards on amyloses with some references.
