Refined carrageenan has a 2% maximum for acid-insoluble material and is produced by alcohol precipitation or potassium chloride gel press process. [19] Semi-refined carrageenan has a much higher cellulose content [21] and is produced in a less complex process. Indonesia, the Philippines, and Chile are three main sources of raw material and ...

Poligeenan is produced by the harsh acid degradation of carrageenan. Carrageenan in solution is processed at low pH (~1.0) and high temperature (90 °C (190 °F)) for up to six hours until the weight-average molecular weight (M w) has been reduced to the range 10,000 – 20,000 daltons (10–20 kDa).
Chondrus crispus—commonly called Irish moss or carrageenan moss (Irish carraigín, "little rock")—is a species of red algae [1] which grows abundantly along the rocky parts of the Atlantic coasts of Europe and North America. In its fresh condition it is soft and cartilaginous, varying in color from a greenish-yellow, through red, to a dark ...
Two bacteria which produce lambda-carrageenase have been found. The marine bacterium Pseudoalteromonas carrageenovora (also known as Alteromonas carrageenovora) strain ATCC 43555, which was isolated from sea water in Nova Scotia, and the deep-sea bacterial isolate Pseudoalteromonas sp. CL19, which was isolated from a sediment sample from Suruga Bay, Japan.
Iota-carrageenase (EC 3.2.1.157) is an enzyme with systematic name iota-carrageenan 4-beta-D-glycanohydrolase (configuration-inverting). [1] [2] [3] This enzyme catalyses the following chemical reaction
Eucheuma denticulatum is a species of red algae and one of the primary sources of iota carrageenan. It exists naturally in the Philippines , tropical Asia, and the western Pacific, [ 2 ] but for the commercial extraction of carrageenan it is usually cultivated.
