A spectrophotometer was used to measure the turbidity of a carrageenan gel as a function of temperature. The optical transmission of the gels was found to decrease as the gels undergo the sol-gel phase transition. The differential of transmission (I) with respect to temperature ( T ), dI/dT, exhibit
NMR chemical shifts and line-widths of 13?Cs ions were measured in kappa-carrageenan gels containing galacto-or gluco-marmans, and compared with measurements on kappa-carrageenan alone. In the mixed gels, as in pure kappa-carrageenan, large changes in the NMR parameters were found to accompany the o
## Abstract The solβgel transition of gelatin, measured by thermal analysis and viscosity measurement, was analyzed in terms of the change in hydration state of polymer molecules. A new thermodynamic model was proposed in which the effect of water potential is explicitly taken into account for the
