The invention relates to the technical field of recycling of trepang cooking liquid and provides a comprehensive and efficient utilization method for a trepang cooking liquid. The method comprises thefollowing steps: performing two-stage membrane separation on a thtrepang cooking liquid, collecting a primary membrane permeating liquid mainly comprising a protein, a polysaccharide and a pigment and secondary permeating liquid mainly comprising saponin and inorganic ions, adding compound protease into the primary membrane permeating liquid for enzymolysis, adding active carbon for decolorationand deodorization after the enzymolysis, performing centrifugation, concentration and spray drying on enzymolysis liquid to form trepang glycopeptide, and performing temperature control foam separation on the secondary membrane permeating liquid to form trepang saponin. The method recovers active ingredients such as the protein, the polysaccharide and the saponin from the trepang cooking liquid simply and effectively, has
