Russian Breakthrough Unlocks Purer Fucoidan from Brown Algae

Russian scientists have developed a new way to extract fucoidan from brown algae. The improved method produces a higher yield of the compound while keeping it pure and biologically active. Fucoidan, known for its antioxidant and immune-boosting properties, could soon appear in food, medicines, and skincare products. The research was carried out by teams from Immanuel Kant Baltic Federal University, Kemerovo State University, and Kaliningrad State Technical University. Their technique involves drying and processing the algae before treating it with a calcium chloride-based solution. This results in a stable powder form of fucoidan, ready for further use.

The compound itself is a complex polysaccharide found in Fucus vesiculosus, a type of brown alga. Studies have shown fucoidan's ability to fight microbes, reduce oxidative stress, and support immune function. Experts believe it could serve as a functional ingredient in next-generation food products, dietary supplements, and advanced skincare formulations.

While Russian researchers have refined the extraction process, similar work has been done elsewhere. At least three scientific institutions in Dalian, China, have published methods using irradiation to extract or degrade fucoidan from brown algae. Australian company Marinova has also produced high-purity fucoidan extracts from the same source. The Ministry of Science and Higher Education of the Russian Federation has highlighted this development as a step forward in fucoidan production. The new method ensures a more efficient extraction without compromising quality. This could expand its use in pharmaceuticals, nutrition, and cosmetics in the near future.
