The global top producers of carrageenan are the Philippines and Indonesia. [4] [5] [6] Carrageenan, along with agar, is used to produce traditional jelly desserts in the Philippines called gulaman. [7] No clinical evidence establishes carrageenan as an unsafe food ingredient, mainly because its fate after digestion is inadequately determined. [8]
Differences in carrageenan chemistry, with Hypneaceae species producing kappa-carrageenan and Cystocloniaceae producing lambda-carrageenan, was another reason for their distinction. [5] However, these criteria were questioned and molecular analysis later showed that the two families had similar vegetative and reproductive characters.

Chondrus crispus—commonly called Irish moss or carrageenan moss (Irish carraigín, "little rock")—is a species of red algae 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 ...
Lamina or blade: flattened structure that is somewhat leaf-like Sorus: spore cluster; pneumatocyst, air bladder: a flotation-assisting organ on the blade; Kelp, float: a flotation-assisting organ between the lamina and stipe; Stipe: stem-like structure, may be absent; Holdfast: basal structure providing attachment to a substrate
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).
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
