The gelation is reversible. In this study we follow the solegel
transition (or conditionally, gel“melting”) by decrease in the storage and loss moduli by temperature scanning.
Fig. 2 illustrates the experimental data.
The“melt transition temperature”is assumed as the crossover
point of both components of the dynamic modulus, as shown in
Fig. 2. The dependence of the melt temperature on the k-carrageenan concentration in modified gel is shown inFig. 3. As seen,this dependence is not smooth and the sharp increase in the solegel transition temperature happens at thek-carrageenan concentration above 0.1 g/100 g or at the gelatin/carrageenan ratio of 10:1.
