Production
Approximate annual production figures from recent
years are as above. |
Biology & Agronomy
Commercial spinosum production is
currently on the order of 25-30,000 dry tons per year at the
commercial standard of 38% moisture-content.
Although some spinosum is
consumed directly as human food most material is used as a source of the
commercially valuable marine biopolymer (red algal galactan) called carrageenan.
Spinosum is
commercially cultivated on a substantial, continuous basis in the
Philippines, Indonesia, Malaysia (Sabah) and Tanzania. Experimental
farming or intermittent commercial activity has occurred in several
countries including China, Japan, Federated States of Micronesia
(Ponape), Fiji, Kiribati, USA (Hawaii) and in Caribbean countries. Local cultivars have
entered commercial production in several places but there has also been
transplantation both within and between countries (e.g. Philippine
stocks to Indonesia and vice versa). |
Chemistry
We also have a monograph in process on the subject of red
algal galactans. These are the basis for commercial marine
biopolymers such as carrageenan and agar.
|
Processing
We have several monographs in progress covering analytical
procedures, post-harvest treatment and semi-refining technology
for Eucheuma and similar seaweeds. Check the processing
index for available web pages and monographs.
|
Products, Uses & Applications
Most Eucheuma is dried, baled or sacked and shipped for
processing into semirefined or refined carrageenan. Some is eaten
fresh as food. Check the Carragar
Links and the Biopolymer
Links for information on these topics.
