As sargassum floods Florida beaches, researchers uncover new use as food-grade ingredient
Researchers from Florida International University and other institutions are studying the potential of sargassum seaweed as a source of food-grade alginate. The study explores using high-pressure processing to remove contaminants and transform the seaweed from an environmental nuisance into a sustainable industrial resource.
