Stabilized paste
Kelp Paste
We process freshly harvested wet kelp into a homogeneous paste with 80% moisture, using mechanical means only and no chemical extraction. It is packed under oxygen displacement to prevent oxidation and decomposition and to ensure the stability of its bioactive compounds, such as fucoidans, alginates and phlorotannins. This format is designed for the cosmetics, nutraceutical, biomaterials and biostimulant industries.

Frequently asked questions
What is the difference between Kelp Paste and Kelp Powder?
Kelp Paste is a stabilized paste with 80% moisture, packed under oxygen displacement and intended for cosmetics, nutraceuticals and biomaterials. Kelp Powder is dried to 12% moisture and milled to ~300 µm, and is aimed at animal feed and agricultural biostimulants.
How is Kelp Paste stabilized and preserved?
It is processed by mechanical means only and packed under oxygen displacement, which halts oxidative and microbial deterioration and keeps the biological activity of key compounds such as fucoidan and alginates intact. 12-month shelf life unopened; once opened, keep refrigerated.
What are the main active compounds in your kelp?
Our formats preserve the whole seaweed matrix: alginate (21–26% dry basis), fucoidan (measured through its indicator, fucose), mannitol and minerals, with total carbohydrates standardized at 28–31% dry basis.
What industrial formats are available for sale and shipping?
1 L and 5 L formats for samples and technical trials, 60 L as the standard format, and bulk sales for large production volumes.
Do you test for contaminants and heavy metals?
Yes. Every batch has certified analyses under ISO/IEC 17025. We monitor and report cadmium, arsenic, lead and mercury to certify safety, as well as pesticides, antibiotics, nitrofurans and dyes.
How can I request technical data sheets or quotes?
