The invention discloses a method for extracting eggshell membrane polypeptide and preparing a bone joint health product, which comprises the following steps: preparing an eggshell raw material, performing acid treatment, filtering, preparing polypeptide powder and organic calcium powder, mixing the polypeptide powder and the organic calcium powder to prepare a joint health-care composition, and then preparing, mixing, granulating and tabletting to obtain the bone joint health-care product. The invention can efficiently prepare eggshell membrane polypeptide and eggshell organic acid calcium by establishing an acid-reduction-enzyme method coupled eggshell membrane treatment technology without complex shell-membrane separation operation, and the joint health-care product prepared by the method is rich in bone joint key health-care nutrient components such as hyaluronic acid, chondroitin sulfate, glucosamine, organic acid calcium, organic acid magnesium and the like, and has the effects of repairing osteoporosis, osteoarthritis and antioxidation. |
