抄録

Multinuclear n.m.r. experiments were carried out to study a selective interaction between group I cations and κ-carrageenan. It was found that the n.m.r. intensity of gel-forming cations undergoes a rapid change in the vicinity of sol-gel transition temperature. On the other hand, the n.m.r. intensity of a non-gel forming cation which coexists with a gel-forming cation does not show any singular behaviour at the sol-gel transition. These results strongly suggest that gel-forming cations selectively interact with κ-carrageenan.
