Abstract
The effect of pH on elastic modulus E and turbidity for mixed gels of gelatin and agar was investigated. For (acylated gelatin)/agar mixed gels, the plot of E against the gelatin concentration CG shows a minimum for the gels at pH 10.1 and a maximum for the gels at pH 3.5. A theoretical model for the phase-separated mixed gels was shown to be partly applicable to the data of E as a function of CG. From the pH dependence of turbidity and E for the mixed gels, a correlation between the turbidity and the elastic modulus of the mixed gels was demonstrated.
