Chemische Eigenschaften
Carrageenan, when extracted from the appropriate seaweed source, is a yellow-brown to white colored, coarse to fine powder that is odorless and tasteless.Occurrence
Irish moss is a seaweed found in Europe and on the coasts of Canada.Verwenden
Carrageenan is a gum that is a seaweed extract obtained from red seaweed chondrus crispus (also known as irish moss), gigartina, and eucheuma species. chondrus crispus yields kappa and lambda carra- geenans. gigartina yields kappa and lambda carrageenans. eucheuma yields kappa and iota carrageenans. it exists as various salts or mixed salts of a sulfate ester. it is classified mainly as kappa, iota, and lambda types which differ in solubility and gelling properties. the kappa and iota types require hot water (above 71°c) for complete solubility and can form thermally reversible gels in the presence of potassium and calcium cations, respectively. the kappa gels are brit- tle with syneresis while the iota gels are more elastic without synere- sis. the lambda type is cold-water soluble and does not form gels. kappa and iota carrageenan are very reactive with milk protein products. carrageenan is used to stabilize milk protein at 0.01–0.05% and to form water gels at 0.5–1.0%. its uses include dairy products, water gel desserts, and low-calorie jellies. a typical use level in water systems is 0.2–1.0% and milk systems is 0.01–0.25%. also termed chondrus extract.Definition
A sulfur phycocolloid: the aqueous, usually gel- forming, cell-wall polysaccharide mucilage found in red algae (Chondrus crispus and several other species). It is water-extracted from a seaweed called carrageen or Irish moss (east coast of southern Canada, New England, and south to New Jersey). It is a mixture of polysaccharide fractions: (1) The λ fraction is cold-water soluble, contains d-galactose and 35% esterified sulfate, and does not gel. (2) The κ fraction contains d-galactose and 3,6-anhydro-d- galactose (1.4:1 ratio) and 25% esterified sulfate. The κ form does not gel without addition of a solute; the properties of the gel depend on the amount and nature of the added solute. Another species of sea- weed produces 100% κ from North Carolina to the tropics. Carrageenan is a hydrophilic colloid that absorbs water readily and complexes with milk pro- teins.Allgemeine Beschreibung
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.Hazard
Questionable carcinogen.Landwirtschaftliche Anwendung
Carrageenans are naturally occurring hydrophilic colloids found in various species of red seaweeds. They perform a role similar to cellulose in terrestrial plants.Carrageenans are a highly sulphated galactan. Due to this they are a strongly anionic polymer which makes them useful commercially. They are commercially extracted for their use as water soluble gums.
Carrageenans may be compared with furcellaran extracted from agars (furcellarans have a smaller proportion of half-ester sulphate). Agars, in contrast, are commonly considered non-ionic
Sicherheitsprofil
Poison by intravenous route. Questionable carcinogen with experimental neoplastigenic and tumorigenic data. When heated to decomposition it emits acrid smoke and fumes.Sicherheit(Safety)
Carrageenan is widely used in numerous food applications and is increasingly being used in pharmaceutical formulations. Carrageenan is generally regarded as a relatively nontoxic and nonirritating material when used in nonparenteral pharmaceutical formulations.However, carrageenan is known to induce inflammatory responses in laboratory animals, and for this reason it is frequently used in experiments for the investigation of anti-inflammatory drugs. Animal studies suggest that degraded carrageenan (which is not approved for use in food products) may be associated with cancer in the intestinal tract, although comparable evidence does not exist in humans.
The WHO has set an acceptable daily intake of carrageenan of ‘not specified’ as the total daily intake was not considered to represent a hazard to health. In the UK, the Food Advisory Committee has recommended that carrageenan should not be used as an additive for infant formulas.

Lager
Carrageenan is a stable, though hygroscopic, polysaccharide and should be stored in a cool, dry place.Carrageenan in solution has maximum stability at pH 9 and should not be heat processed at pH values below 3.5. Acid and oxidizing agents may hydrolyze carrageenan in solution leading to loss of physical properties through cleavage of glycosidic bonds. Acid hydrolysis depends on pH, temperature and time. The acid hydrolysis takes place only when the carrageenan is dissolved, and the hydrolysis is accelerated as the processing temperature and/or the processing time is increased. However, when the carrageenan is in its gelled state the acid hydrolysis no longer takes place.
l?uterung methode
This D-galactose-anhydro-D or Lgalactoside polysaccharide is precipitated from 4g of Carrageenan in 600mL of water containing 12g of KOAc by addition of EtOH. Collect the fraction that precipitates between 30 and 45% (v/v) of EtOH and dry them in vacuo. [Pal & Schubert J Am Chem Soc 84 4384 1962.]Inkompatibilit?ten
Carrageenan can react with cationic materials. If complexation of cationic materials, with associated modification of the active compound’s solubility, is undesirable, the use of carrageenan is not recommended.Carrageenan may interact with other charged macromolecules, e.g. proteins, to give various effects such as viscosity increase, gel formation, stabilization or precipitation.
