Determination of the intrinsic visc

Determination of the intrinsic viscosity can be an indication
of the molecular structure of the samples. However, the samples
should be fully solubilized in a proper solvent before the
experiment. Determination of the solubility of the samples (as
determined according to Majzoobi and others 2003) showed that
all of the samples were at least 95% soluble in 1 mol/L KOH (data
are not given). Therefore, the samples were completely soluble
under the condition used for starch solubilization. The results of this study (Figure 1)
