Technical
Specification
Raw dried Kappaphycus alvarezii. Everything a buyer needs to decide whether to ask for a sample.
The analytical figures below are published ranges for this species, given so you can see the parameters we contract on. They are not Ceylon Seaweeds' own laboratory results. Batch-specific analysis is issued against a sample request, and contracted values are agreed per shipment.

The product as shipped.
| Parameter | Indicative |
|---|---|
| MoistureOn delivery, sun-dried. Lower is better; buyers commonly contract to a ceiling. | 21.7 – 33.5 % |
| AshTotal ash. Reflects mineral uptake and any residual salt or sand from drying. | 33.7 – 43.1 % |
| Carrageenan yieldRecoverable kappa-carrageenan by dry weight. | 11.4 – 13.6 % |
