The effects of Naþ, Kþ, Caþþ and Mgþþ cations on the sol–gel transitions of high acyl (HA) gellan dispersions were investigated. Gelling temperatures of 1% HA gellan dispersions containing selected cations (monovalent cations, 10–200 mM; divalent cations, 2–80 mM) were determined using dynamic rheological analysis. Gelling temperatures increased with cation concentrations. Divalent cations exhi...
