The present invention is directed to a process for obtaining at least one of fucoidan and laminarin from live, harvested seaweed, wherein the process comprises the steps of: (i) harvesting seaweed comprising fucoidan and laminarin to obtain live, harvested seaweed, wherein the live, harvested seaweed exudes to form an exudate solution; (ii) collecting the exudate solution from the live, harvested seaweed, wherein the fucoidan and laminarin are dissolved in the exudate solution; and (iii) separating the at least one of fucoidan or laminarin from the exudate solution.

Process for isolating fucoidan and laminarin from live, harvested seaweed

The present invention concerns a process for the production of alginate having a mannuronic acid-content of at least 80 mole %, wherein said alginate is produced by: a) adding algae or seaweed to water under stirring, in a ratio of 1:3 to 1:20 respectively, at a pH above about 2.3, while maintaining a temperature above 20&#xb0; C. for at least 30 minutes, and b) separating said alginate from the solid material of the suspension in a) by a standard separation method such as filtration, and optionallyc) recovering said alginate from the solution.

Process for the production of alginate having a high mannuronic acid-content

A new procedure for producing block fractions from alginate, mainly G block alginate or M block alginate, by selective fractionated release of the M block fraction from the solid phase. MG block fractions can also be isolated.
