Free radical scavenging activity of extracts from seaweeds Macrocystis pyrifera and Undaria pinnatifida: applications as functional food in the diet of prawn Artemesia longinaris
Water-soluble extracts from seaweeds Macrocystis pyrifera (M) and Undaria pinnatifida (U) were prepared to use the polysaccharide bioactive fraction as functional food. Chemical analysis showed that the main components of both extracts were mannitol and fucoidans. Also in both cases minor amounts of...
