The aim of the present work has been to study the influence of rest time on the structural development of gluten/glycerol mixtures with gluten volume fraction ranging from 0.56 to 0.75 by equibiaxial and uniaxial deformations at room temperature. The Gaussian and the Mooney-Rivlin relations are used to evaluate shear moduli at small and medium strains and the Kohlrausch-Williams-Watts (KWW) model is used to analysis relaxation modulus at biaxial strain 0.7. Shear moduli and average relaxation time are discussed in relation to gluten content for the mixtures with a rest time of 150min and also to a mixture of 0.61 gluten volume fraction with different rest times.
