Using Ziziphi Spinosae semen as raw material, Ziziphi Spinosae semen protein was extracted by alkali extraction and acid precipitation method. The Ziziphi Spinosae semen protein was hydrolyzed by three different proteases (alkaline protease, neutral protease and papain). The functional properties and antioxidant activity of enzymatic hydrolysates from Ziziphi Spinosae semen protein were studied. The results showed that the solubility, oil holding capacity, foaming capacity and stability, emulsifying capacity and stability of protein hydrolysates from different Ziziphi Spinosae semen were improved in different degrees compared with protein hydrolysates from Ziziphi Spinosae semen, among them, papain hydrolysate had the strongest solubility, oil holding, foaming and emulsifying properties, and alkaline protease hydrolysate had the strongest foaming and emulsifying stability. In vitro antioxidant studies showed that compared with of Ziziphi Spinosae semen protein, the antioxidant activities of enzymatic hydrolys
