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
