Russian breakthrough unlocks high-purity fucoidan from brown algae

Russian researchers have developed a new way to extract fucoidan from brown algae. The improved method boosts yield while keeping the compound's purity and beneficial properties intact. Scientists believe this breakthrough could expand fucoidan's use in healthcare, nutrition, and biotechnology. The study was carried out by a team from Immanuel Kant Baltic Federal University, Kemerovo State University, and Kaliningrad State Technical University. Their findings were reported by the Ministry of Science and Higher Education of the Russian Federation.

Fucoidan is a complex polysaccharide found in brown algae, specifically *Fucus vesiculosus*. Known for its antioxidant, antimicrobial, and immune-boosting effects, it has drawn interest across multiple industries. However, traditional extraction methods often struggled with low yields or compromised bioactivity. The new process starts with drying and preparing the algae. A calcium chloride-based solution is then used to isolate fucoidan more efficiently. The result is a stable powder form, ready for further processing. Unlike earlier techniques, this approach maintains the compound's purity and functional benefits. Experts highlight fucoidan's potential as a functional ingredient in next-generation food products. While studies over the past five years have explored its applications, no exact count of food industry uses has been documented.

The improved extraction method could make fucoidan more accessible for commercial and scientific use. Its stability in powder form and preserved bioactivity may lead to wider adoption in healthcare and nutrition. The Ministry of Science and Higher Education's report suggests further research will explore these possibilities.
