Gellan gum is currently commercially available in both the high acyl and the low acyl form When hot solutions of gellan gum are cooled in the presence of gel-promoting cations gels of various textures can be formed principally through cation-mediated helix–helix aggregation (Gibson Sanderson 1997)

gellan gum_

Gellan gum molecules undergo a thermally-reversible coil to double-helix transition with decreasing temperature and double-helical molecules aggregate and form junction zones in gels (Nijenhuis 1997) The coil to double-helix transition is a prerequisite for gel formation of gellan gum (Nishinari 1997)
