Effect of Different Pretreatment on Antioxidant Activity of Auricularia auricula Polysaccharides
[Objective]To analyze the antioxidant activity of Auricularia auricula polysaccharides,and provide support for the produc-tion and application of Auricularia auricula polysaccharides.[Method]The scavenging capacity of Auricularia auricula polysaccharides on OH,O2 and DPPH free radicals was tested after drying at 85 ℃ and extrusion pretreatment. In addition,the composition of Auricularia auricula residue was determined[Result]Auricularia auricula polysaccharides showed good antioxidant activity,and the residue of Auricularia auricula contains more nutrients.[Conclusion]85 ℃ drying and extruding pretreatment are feasible pretreatment methods,and Auricularia auricula residue can be further developed and utilized.
