Abstract:Objective:Isolation antioxidative peptide from ovalbumin by enzymatic hydrolysis. Method:Antioxidative peptides in the hydrolysates were purified by ultrafiltration(UF) membrane system, Q-Sepharose FF ion-exchang chromatography and reverse phase high-performance liquid chromatography(RP-HPLC). Their structure was further identified by electrospray ionization tandem mass spectrometry (ESI-MS/MS). Result:Three peptides with strong antioxidative activities were purified from the hydrolysates. Their structure w...
Keywords:ovalbumin  enzymatic hydrolysis  antioxidative peptide  isolation
