The present invention concerns a process for the production of alginate havi ng 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 o f 1:3 to 1:20 respectively, at a pH above about 2.3, while maintaining a temperature above 20 ~C for at least 30 minutes, andb) 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. |
