Red algae (Rhodophyta) Carrageenan is made from Gigartina stellata, Chondrus crispus and Eucheuma.
Carrageenan (carrageenin, carragheen) is similar to agar, but requires higher concentrations to form gels.
Red algae (Rhodophyta) Agar is made from Gelidium, Gracilaria, Pterocladia and Ahnfeltia.
Agar is another colloidal agent used for thickening, suspending, and stabilizing. However, it is best noted for its unique ability to form thermally reversible gels at low temperatures.
