MC as well as most polysaccharide polymers is known to have strong viscosity enhancing (Staudinger & Schweitzer, 1930), as well as visco-elastic properties in solutions (Castelain et al., 1987 and Robinson et al., 1982). Prior to the analysis of the influence of different applied frequencies and shear rates on the gelation temperature, the impact of these parameters were investigated at a constant temperature. Fig. 1 shows the frequency dependence of the storage modulus, G′, and the loss modulus, G″ (which characterize, respectively, elastic and viscous response) as a function of the concentration of a methylcellulose in aqueous solutions at 20 °C. All these experiments were conducted inside the linear visco-elastic region of the applied deformation.
