Abstract: To research the antioxidant capacity in vitro of Termitornyces albuminosus beverages,the abilities of the beverages to scavenge DPPH free radicals( DPPH·),superoxide anion( O_2~-·),hydroxyl(·OH) and ABTS radical( ABTS~+·) were determinated in this paper. The total antioxidant capacity under the environment of artificial simulation gastric and intestinal juices and oil antioxidant effect of the beverages were also studied in the experiment. The results showed that Termitornyces albuminosus beverages and V_C( 0.2 mg/mL) had effective ability to scavenge DPPH·,O_2~-·,·OH,ABTS~+·,and the scavenging activity from strong to weak order was V_C> 1 ∶ 5 full mushroom drinks > 1 ∶ 5 mycorrhizal beverages > 1 ∶ 10 full mushroom drinks.The total antioxidant activity in the artificial simulated gastric and intestinal juice of the beverages and V_C were lower than that in normal solution.The beverages also had certain antioxidant effect to lard oil and sesame oil while its antioxidant was smaller than that of V_C and V_E( 0.2 mg/mL).Therefore,Termitornyces albuminosus beverages had strong antioxidant capacity in vitro and merited development.
