Iota Carrageenan is a natural gelling agent derived from red algae, used to create smooth and elastic gels.
Like Agar-Agar, carrageenan is obtained from the cell walls of red algae. Iota Carrageenan is a vegan food additive that usually produces an elastic gel that does not degrade if it is frozen and thawed. It also forms a stronger gel in the presence of starch.
Iota Carrageenan is used mostly to gel mixtures – it is more rubbery in texture. The gel type is thermo-reversible with an elastic and cohesive texture. The gel temperature increases with ion concentration, with values ranging from 40C – 70C, and has a fast setting time. Iota is freezer stable and has an ion sensitivity in the presence of calcium or potassium. Once you shear Iota a gel will form and be loaded with a flavorful release. Moreover, iota forms gels at very low concentrations with milk.
