Abstract
ABSTRACTEgg white from which the precipitate occurring during dialysis against water had been removed gave a transparent gel on heating at lower salt concentrations and pH 3.54. The addition of NaCl or a shift of pH from 3.54 to 4.50 brought about the turbid gels. Creep analyses of these transparent and turbid gels were done using a four‐element mechanical model. The instantaneous elastic modulus, E0, Newtonian modulus, ηn and retarded viscoelastic moduli, E1 and η1 increased with NaCl up to 125 mM and then decreased with increase in NaCl concentration at pH 3.54. At 125 mM NaCl and pH 3.54, a translucent gel was obtained. E0 and η1 decreased with the temperature of the gel, while E1 and η1did not change depending of temperature.
