An efficient method for the degradation of polysaccharides isolated from Sargassum fusiforme (PSF) was developed by using ascorbic acid in combination with H2O2. The degradation conditions were optimized using a Box-Behnken response surface design (BBRS). The optimum conditions were established as: concentration of ascorbic acid (VC) and H2O2 17.26mM, degradation temperature 51°C and degradation time 1.6h. The DPPH radical scavenging rate of the degraded polysaccharides from S. fusiforme (DPSF) obtained under the optimal conditions was determined to be 75.22±0.02
