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