Description
Sun-dried, cleaned whole seaweed of Eucheuma spinosum (now classified Eucheuma denticulatum), the principal raw material for iota-carrageenan-iota-high-purity" class="underline" style="color: var(--sage-deep); text-decoration-color: var(--sage-deep);">carrageenan production. Distinguished from cottonii by its spiny morphology and elastic-gel polysaccharide profile.
Light tan to brown dried thalli with distinctive spiny branchlets. Faint marine aroma. Cultivated alongside cottonii in tropical Southeast Asian shallow waters.
We supply Eucheuma Spinosum Crude from China-based processing partners with cross-border sourcing from Indonesia, the Philippines, Tanzania, and surrounding regions, holding ISO, Halal, Kosher and other certifications relevant to the product and production.
Common market grades include sun-dried whole-thallus, salt-cured pressed bales, and machine-cleaned hygienic-grade material for food use.
Bulk and reduced-MOQ shipments. Batch-level COA covering carrageenan yield, moisture, salt content, impurities, and microbiology.
Introduction
Eucheuma denticulatum, commercially known as Eucheuma spinosum, is the second-most important commercially cultivated carrageenan seaweed after Kappaphycus alvarezii. It produces predominantly iota-type carrageenan, which forms elastic, thermo-reversible gels with calcium ions.
The cultivation footprint overlaps with cottonii but is smaller in absolute volume, reflecting the more specialized iota market versus the dominant kappa market. Cultivation areas are concentrated in Indonesia, the Philippines, and the East African coast.
Iota carrageenan's elastic gel character is preferred in dairy desserts, yogurt stabilization, and milk-protein systems where a soft, freeze-thaw-stable gel is required. Kappa carrageenan's firmer gel is preferred for meat, pet food, and confectionery.
Buyers of crude Eucheuma spinosum operate downstream extraction or supply specialty iota-rich blends to the dairy and dessert sectors.
Where it is used
- Industrial extraction of refined iota carrageenan
- Industrial production of iota-type PES
- Dairy dessert and yogurt stabilization applications
- Whole-seaweed culinary use in Southeast Asia
- Cosmetic ingredient for elastic-gel applications
- Animal feed and aquaculture
- Bioplastic and biofilm research
- Traditional dessert and confectionery in island cuisines
