Study of anti-oxidative improvement on corn activity peptides with nanotechnology

Objective:To observe the effect of corn activity peptides with nanotechnology on anti-oxidative levels compared with corn activity proteins.Methods:Corn activity peptides were made from corn activity proteins through nanotechnology treatment.Corn activity peptides and proteins were analyzed by high performance capillary electrophoresis（HPCE）. Anti-oxidative levels in them were detected in a chemiluminescence system.Results:With nanotechnology new small molecules peptides were found and some macromolecule proteins disappeared in corn activity peptides compared with the corn activity proteins.Anti-oxidative level of corn activity peptides was obviously elevated compared with the corn activity proteins and dramatically accelerated with polyethylene glycol.But the level dropped with time prolonging.Conclusion:Component in corn activity peptides with nanotechnology was different from corn activity proteins.New small molecules peptides were helpful to enhance the anti-oxidative ability in corn activity peptides.
