Abstract:Animal blood is rich in a larg e amount of hig h-quality proteins,especially the hemog lobin accounts for 60~70% of the content of total blood protein.Bioactive peptides derived from hemog lobin have a lot of important biolog ical activities,and it can be developed for biolog ical products with hig h value added as the function food,medicine and cosmetics,etc..But major of animal blood is discharg ed or abandoned in form of sewage,which causes a large amount of valuable nutrition resource loss and it has broug ht serious environmental pollution. Processing hemog lobin not only can fully utilize a large number of valuable proteins in the blood to prepare bioactive peptides,but also contribute to protection of the environment.The research prog ress of functional activity of bioactive peptides derived from hemog lobin in recent years has been described sy nthetically,and this paper has looked forward to the application prospect of bioactive peptides derived from hemog lobin.
