Structure and rheological characterization of konjac glucomannan octenyl succinate (KGOS)

The HPLC method was established to measure the reaction extent of KGOS (A). KGOS aggregated particles formed irregular spheres or ellipsoids (B). KGOS solution fit to non-Newtonian fluid properties and the Carreau model, and the type and valence of the ions affected the apparent viscosity of KGOS solution. The trends of the dynamic mechanical spectra indicated KGOS solution could be an entanglement system (C).90
