Ascophyllum is not farmed and is harvested intensively in many
areas of its distribution.

Chemistry
Contains alginates. SuriaLink has a monograph in preparation on the chemistry of
alginates. |
Processing
We have several monographs in progress covering analytical
procedures post-harvest treatment and process technology. Check

Products, Uses & Applications
Ascophyllum is (or has been) a significant source of
raw material for the alginate industries of Eastern North America
and Western Europe. Dried, pulverised Ascophyllum is used
as a "meal" for use as an animal feed additive and it is
also used as a raw material for the production of hydrolysates
used as plant food or fertiliser.
