ABSTRACT

Based on experimental measurements of apparent viscosity and employing the Ostwald-de Waele model, a number of mathematical functions were obtained representing the pseudoplastic thixotropic behaviour of hydrogels prepared with microcrystalline cellulose-sodium carboxymethyl cellulose (MCC-NaCMC) and four types of starch of different origin (corn, potato, rice and wheat). The results obtained corresponding to each parameter of the model and for each gel were analyzed as a function of starch concentration and agitation time.
