文摘
- •
The polysaccharide from E. prolifera was degraded effectively by H2O2 and Vitamin C.
- •
Degraded polysaccharide was carboxymethylated to improve its antioxidant activity.
- •
Conditions for carboxymethylation were optimized by Response Surface Methodology.
- •
The antioxidant activity of carboxymethylated extract was greatly enhanced.
