Enhancing Antioxidant Activity of Soluble Polysaccharide from the Submerged Fermentation Product of Cordyceps sinensis by Using Cellulase

Abstract:

Soluble polysaccharide is a main bioactive composition of Cordyceps sinensis. To increase its antioxidant activity, 500 mg of submerged fermentation products of C. sinensis was incubated with 7.5 U or 375 U of cellulase in 50 mL of water at 50°C for 2 h. The content of soluble polysaccharide of submerged fermentation products of C. sinensis increased from 30.28% to 33.23~38.10%. At the same concentration, the DPPH free radicals scavenging capability and reducing power of cellulase-treated soluble polysaccharide were higher than those of untreated control.
