Concentration Range: 0.2-1.0% for most applications. Twice as viscous as Agar at equal concentrations.
Dispersion: Gellan gum will disperse in cold water, but dispersion is aided by the use of warm to hot water, sugar, alcohol, or glycerin.
Hydration: Happens at around 194°F/90°C. Can be hydrated at low pH, around 3.0 or 4.0, which is unique amongst hydrocolloids.
Setting: Sets rapidly at relatively warm temperatures (see above for exact numbers).
Special uses: Spherification
Low-acyl Gellan Gum can be used instead of sodium alginate for spherification and reverse spherification due to its sensitivity to calcium ions.
