Low Acyl/High Acyl Gellan Gum
Temperature (High Acyl): Hydrates at 185°F/85°C, Gels from 158-176°F/70-80°C, Melts from 160-167°F/71-75°C
Temperature (Low Acyl): Hydrates between 167-203°F/75-95°C, Gels from 50-122°F/10-50°C, Melts from 176-284°F/80-140°C
The reason the temperatures vary is because the exact temperature will depend on concentration of Gellan used.
Texture: Low-acyl Gellan is generally considered brittle while high-acyl Gellan is more elastic. It is possible to combine the two to create the exact desired texture.
Appearance: High-acyl Gellan is opaque, low-acyl Gellan is clear.
Flavor release: Good, for both varieties.
Mouthfeel: Both have a clean mouthfeel; low-acyl Gellan has been described as "creamy" as well.
Freeze / Thaw stable: High-acyl Gellan is freeze/thaw stable. Low-acyl Gellan is not.
Syneresis (weeping): Generally not.
Shearing: Creates a shear-thinned gel, otherwise known as a fluid gel.
Due to its good rheological characteristics, gellan gum is a bacterial polysaccharide with great commercial potential for food, pharmaceuticals, and particularly environmental bioremediation.
