Regional development plan for agar production from red algae Furcellaria

Kurzeme, Latvia

furcellaria_303x148Furcellaria lumbricalis, which is a valuable raw material for the production of agar, is one of the most common species of algae in the seacoast of Latvia with the highest total amount of biomass. The amount of the material which can be collected in the coastal territory seasonally is 52,366.67 m3. At the moment more compact furcellaria stands are found in the seacoast stage Nida – Liepāja, and high distribution potential keeps up to Akmenrags, where is a suitable bottom substrate for algal growth.

The process of agar production includes different steps such as algae collection, drying, extraction, filtration, concentration and milling, of which some are highly energy-intensive processes. Therefore in order to ensure successful production of agar, there is a need to ensure the energy source as, for example, biogas stations. The most profitable agar production cycle consists of 8,5 kg furcellaria dry matter from which 1 kg of agar can be obtained.

 

Agar – a substance with many applications

Agar has a wide variety of uses, but mainly it is used in production of food products, which is due to its high gelling ability and the special gel structure. It is also used as a vegetarian gelatin substitute, as well as in pharmaceutical manufacturing, and in dentistry, biomedicine and biotechnology.
Main findings show that agar production would have a positive impact on Kurzeme region, since the production would promote development and increase economic competitiveness of the region.
