What is Carrageenan Made of?

Where is carrageenan obtained from?

The main species of Rhodophyceae used in the commercial production of carrageenan include Eucheuma cottonii and E. spinosum, now reclassified as Kappaphycus alverezii (`Cottonii') and Eucheuma denticulatum (`Spinosum').

Eucheuma cottony and E. spinosum are now heavily used by carrageenan producers and are harvested in large quantities in Indonesia and the Philippines.

How is Carrageenan Made?
