Abstract:

The rheological performance of konjac glucomannan (KGM) sol was investigated in alcohol/water solution, and the structure of KGM films were analyzed. The results showed that the dependent relation between the rheological properties and alcohol concentraiton, the viscosity increased with the concentration of alcohol increasing until the inflexion point of 11%. The results of KGM films analyzing indicated that alcohol promoted KGM film partially formed ordered layer arrangement, and the crystallinity gradually increased with the increase of alcohol concentration, then the transmittance and water absorption decrease.
