抄録

Effect of molar mass of two polysaccharides, xanthan and galactomannan on the synergistic interaction of them was investigated by dynamic shear modulus and differential scanning calorimetry (DSC). Totally 8 samples were prepared. All the combinations of three xanthan whose molar mass is ranging from 2.5×105 to 7.5×106 and five galactomannan (locust bean gum) ranging from 2.8×103 to 5.8×10 5 were measured. The transition temperatures decreases with decreasing molar mass of locust bean gum, but are almost independent on that of xanthan. For the lowest molar mass locust bean gum, no DSC peak and no large increase of shear modulus were found, indicating no synergistic interaction. These effects were discussed based on the commonly accepted model of the crosslinking mechanism for this system, the binding site of the locust bean gum is consecutive unsubstituted mannose backbone.
