Materials and Methods

Because j\* data are obtained at low strains with minimal alteration of the STD structure, they provide unique opportunities for studying applicable models. Although the empirically obtained frequency shift factor (Ferry, 1980) has been used successfully in time-temperature superposition studies on food polymer dispersions (Lopes da Silva et al., 1994), the applicability of similar (if not identical) scaling of frequency still needs to be explored for STD.
