Carrageenans are mucopolysaccharides from the cell walls of the red algae. They
are anionic linear polymers composed of 1,3α-1,4β-galactans having one (κ-), two
(ι-) or three (λ-) sulfates per disaccharide unit. In ionic solutions, κ- and
ι-carrageenans self-associate into helical structures that form rigid or
flexible gels, respectively. λ-carrageenans do not form helices and are
non-gelling. Carrageenans are used commercially as thickeners and stabilizing
agents.

A
substance with hydrocolloid properties obtained from certain members
of the class Rhodophyceae (red seaweeds). The principal commercial
sources of carrageenans are the following families and genera of
the class of Rhodophyceae: Furcellariacaea such as Furcellaria Gigartinaceae
such as Chondrus, Gigartina, Iridaea Hypnaeceae such as Hypnea Phyllophoraceae
such as Phyllophora, Gynmogongrus, Ahnfeltia Solieriaceae such as
Eucheuma, Anatheca, Meristotheca.
