Abstract:  The solubility of shark cartilage in HAc and NaOH solution and their insoluble residues after being treated by boiling water, Papain, HAc and NaOH solutions and analyzed by Differential Scanning Calorimetry(DSC) were investigated. Shark carilage was more soluble in the NaOH sOlution than in the HAc solulion. The solubility of shark carttilage in the 40% HAc solutlon after being steam - cooked at 0.05 MPa pressure was increased to 34. 2% in comparison with that without being treated. The result of DSC showed that endothermal peak at 76～83℃mainly was due to the denaturation of collagen in the shark cartilage and carbohydratd protein greatly contributed the greatest cartilage and exothermal peak at about 360℃。
