The invention provides shark composite short chain polypeptide having anti-inflammatory activity and a preparation method and application, and relates to the technical field of marine organisms. The preparation method comprises the steps of shearing sharks which are fresh or unfrozen after
frozen storage and deboned into small blocks, removing fat with an
alcohol solution, performing repeated rinsing until the sharks are tasteless, and performing draining; performing immersing and
scalding treatment on the shark blocks with pure water; performing cooling to
room temperature, performing homogenization treatment, performing enzymolysis with
proteases to obtain enzymatic
hydrolysate, and performing heating for ending a reaction; performing crude filtering on the enzymatic
hydrolysate, performing
centrifugation treatment, taking supernatant, performing filtering, removing solvents from filtrate, performing sterilization and
drying, and obtaining the shark composite short chain polypeptide.The shark composite short chain polypeptide has anti-inflammatory activity, can be applied to functional foods and special medical formula foods as ingredients, and has notable biologic activity of resisting inflammatory, nourishing the liver, protecting the
kidney and the like. Conventional complex working procedures for treating raw materials are simplified, the shark composite short chain polypeptide having favorable anti-inflammatory
efficacy can be obtained, and industrial large-scale cost-effective production purpose can be achieved.
