Brown algae contain fucoidan, a polysaccharide with promising properties for medical and cosmetic applications. However, the features of fucoidan vary according to source and other factors. In order to find the most suitable fucoidan for a certain application, the polysaccharide has to be precisely analysed in different chemical and biological test systems.

Process chain

The composition of the brown algae depends on various factors such as its location, the environmental conditions to which they were exposed to or the time of harvesting. Molecular weight, glycan structure and Fucoid content may vary. In order to be able to use the natural resource for the project, existing algae are first collected and prepared for further processing. In addition, strategies are developed to cultivate brown algae for commercial use.

Fucoidan is to be extracted from brown algae following standard protocolls, chemically characterised and analysed with regard to its bioactivity. The test results are recorded in a knowledge database. The database is used to determine the Fucoidans suitable for pilot testing.

During the project, the most promising fucoidan candidates are further tested for application in the areas of ophthalmology (age-related macular degeneration - AMD), tissue engineering and cosmetics.

Within the scope of the project, business models for the knowledge database and the application areas are developed and a technology roadmap is created. Furthermore, a concept for the development of a valuechain around the use of Fucoidane is planned.
