Descrizione generale

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.
insoluble in hot concentrated salt solutions

Applicazioni

Carrageenans are used to suppress immune response in vivo and in vitro via mechanisms believed to involve selective cytopathic effect on macrophages. As ι-, κ-, and λ-carrageenans have varying degress of sulfation, they may be studied comparatively for differences in protective, antiviral, and immunosuppression activities.
May be used in immobilization of microbial cells based on the growth of cell in gel

Polysaccharides such as kappa carrageenan are often utilised in fat replacement techniques in the food industry. However, the structural role they can provide within a product is limited by their hydrophilic nature. Hydrophilic particles can be surface-activated by hydrophobic modification

Carrageenans obtained from seaweeds can be processed into films for a range of applications including food packaging. The level of carrageenan refinement during extraction can influence the key properties, with semi-refined carrageenan (SRC) containing more impurities than the more refined
