Base on konjac glucomannan (KGM), using molecular dynamics simulation and modern instruments analysis, the interaction points of hydrogen bond were predicted, the microcosmic interaction process among KGM and k-carrageen,guar gum,soybean protein isolated were researched. The details are specified as follows:1 Research of KGM and guar gum interactionUsing computing molecular structure software: Hyperchem7．0 and methods of molecular dynamics simulation, the microcosmic interaction process between KGM and guar gum was researched. Meanwhile, the results of molecular dynamics simulation were confirmed by experiments. For the first time, the microcosmic interaction process between KGM and guar gum in vacuum is proposed, we obtained the following results: synergistic effect of KGM and guar gum was founded out; the viscosity of mixing gel was decreasing with the increasing of temperature, and its rheological property was improved, but the properties of mixing gel were not excellent enough. By the analysis of the result of molecular simulation, we found that chemical group does not change in essence but hydrogen-bonded function increases,the connected points of hydrogen bond are O(2),O(5),O(6) of mannose of KGM, acetyl group of KGM; and O(6) of mannose of guar gum, O(2) of glucose of guar gum.2 Research of KGM,guar gum and k-carrageen interactionUsing computing molecular structure software: Hyperchem7．0 and methods of molecular dynamics simulation, the microcosmic interaction process among KGM,guar gum and k-carrageen was researched. Meanwhile, the results of molecular dynamics simulation were confirmed by experiments. We obtained the following results combining past research and references: the excellent mixing gelatin formation was possible under the optimal conditions between KGM,guar gum and k-carrageen. The gel strength and the gelling properties of the mixing gel were improved greatly. By the analysis of the result of molecular simulation, we found that KGM molecular guar gum molecular and k-carrageen molecular twined closely, and network structure formatted because of molecular chains rearrangement under high temperature. They are mainly connected by hydrogen bond and the connected points of hydrogen bond are O(2),O(5),O(6) of mannose of KGM, acetyl group of KGM; O(6) of glucose of guar gum, O(2) of mannose of guar gum; vitriol group and O(6) of k-carrageen sugar group.3 Research of KGM and soybean protein isolated interactionUsing computing molecular structure software: Hyperchem7．0 and methods of molecular dynamics simulation, the microcosmic interaction process between KGM and soybean protein isolated was researched. Meanwhile, the results of molecular dynamics simulation were confirmed by experiments. We obtained the following results: although KGM and soybean protein isolated can format mixing gel under the optimal conditions, the mixing gel properties was not excellent enough. By the analysis of the result of molecular simulation, we found that synergistic effect of KGM and soybean protein isolated was because of hydrogen bond. The connected points of hydrogen bond are O(2),O(5),O(6) of mannose of KGM; and amino of soybean protein isolated, carbonyl of soybean protein isolated. 4 Research of KGM,k-carrageen and soybean protein isolated interactionUsing computing molecular structure software: Hyperchem7．0 and methods of molecular dynamics simulation, the microcosmic interaction process among KGM,soybean protein isolated and k-carrageen was researched. Meanwhile, the results of molecular dynamics simulation were confirmed by experiments. We obtained the following results combining past research and references: the excellent mixing gelatin formation was possible under the optimal conditions between KGM,soybean protein isolated and k-carrageen. The gel strength and the gelling properties of the mixing gel were improved greatly. By the analysis of the result of molecular simulation, we found that KGM molecular,soybean protein isolated molecular and k-carrageen molecular twined closely. The main forces among three kinds of molecular were hydrogen bond force and electrostatic force, and the connected points of hydrogen bond are hydroxyl,vitriol group,amino group,carbonyl group.
