A multinuclear NMR study was carried out to study the interaction between group I cations (Na+, K+, and Rb+) and gellan gum. It was found that the NMR parameters of 39K and 87Rb ions undergo an abrupt change in the vicinity of the sol-gel transition temperature. On the other hand, the NMR parameters of 23Na do not show any singular behavior. These results suggest that 39K and 87Rb ions (so-called gel-forming cations) selectively interact with gellan gum.
