igh acyl gellan gum fully solubilizes once heated and forms a soft, elastic gel upon cooling. High acyl gellan gels do not need any cation addition to gel and are thermally reversible.high acyl gellan gum forms soft elastic gels.
Low acyl gellan gum also solubilizes once heated but forms hard, brittle gels upon cooling. The presence of a cation such as Ca2+, Mg2+, Na+or K+is needed for low acyl gellan to gel. Low acyl gellan forms gels that are not thermally reversible.low acyl gellan gum forms
