Recent trends in chemical modification and antioxidant activities of plants-based polysaccharides: A review

• Plants-based polysaccharides were easily and successfully modified with the help of sulfation, phosphorylation, carboxymethylation and selenization. • Modification methods of plants-based polysaccharides were well differentiated according to their reported protocols. • Antioxidant activities of plants-based polysaccharides were improved significantly ( p < 0.05) after chemical modification. The increasing consumption of plants-based...
