Rupture stress and dynamic viscoelasticity were observed for cylindrically moulded gellan gum gels as a function of alkaline-earth metal salts (MgCl_2, CaCl_2, SrCl_2 and BaCl_2) and polymer concentration. Rupture stress and dynamic viscoelasticity of gellan gum gels containing alkaline-earth metal salts increased up to a certain salt concentration. In the case of gels containing SrCl_2, these increases were observed up to a certain salt concentration and after the drop of these value, then these increased again. Transparency of gellan gum gels containing higher concentration of salt and gellan gum was significantly lower than that of lower concentration of salt and polymer. Syneresis of gellan gum gels containing MgCl_2, CaCl_2, SrCl_2 and BaCl_2 did not observe the signifcant difference.
