摘要：
The mechanical behaviour of a composite gel consisting of washed gelatinized starch granules embedded in an egg-white protein gel matrix has been investigated. The shear modulus of the composite gel is dependent on the shear modulus of the matrix, the relative deformabilities of particle and matrix and the volume fraction occupied by the particles. The strength of this gel is affected by stress localization at the filler-matrix interface. Mixed starch-egg-white protein gels contain solubilized amylose, the immiscibility of the amylose and protein also affecting mechanical behaviour.
