Abstract:Porcine blood is one of the main by-products of slaughtering and processing， and is rich in nutrients， including macromolecules and small molecules with specific physiological functions， such as immunoglobulins，bioactive peptides，heme，and enzymes，including superoxide dismutase.It has broad prospective applications.In this paper，the preparation and modification of plasma protein powder，blood red egg white powder， heme， bioactive peptides， and other prevalent functional components of porcine blood were summarized to provide a reference for research and other applications for porcine blood derived resources.
