Abstract
Ziziphus jujuba is a medicinal plant with well demonstrated biological functions for which various bioactive compounds except antioxidants peptides from seeds have been reported Therefore the aim of this study was to determine antioxidant activity metal ion chelation and reducing power of Z jujuba seedsderived protein hydrolysate The concentration of protein was 572 mg/g in 50 mM TrisHCl buffer pH 75 The solubility of protein was above 90 at pH 2 and 3 decreased at pH 4 and subsequently increased further with an increase in pH The seed derived protein showed an excellent solubility and possessed interfacial properties which were governed by their concentrations The antioxidant activities of protein hydrolysate were evaluated using various in vitro antioxidant assays Alcalase papain and protease hydrolysate shows 809 914 and 892 µM of TE/g antioxidant capacity by ABTS and radical scavenging activity 721 1754 and 836 by DPPH From this study it was observed that the papain hydrolysate of Ziziphus jujube is a good source of natural antioxidants and peptides with interesting functionalities
