Abstract Abstract: A new kind of synthetic protein & calcium supplement was made from silver carp bone, The fit hydrolysis and activation conditions for fish polypeptide and calcium powder producing from silver carp bone were investigated. The result suggested that the suitable conditions for hydrolysis with papain was papain dosage 5000U/g（fish bone),hydrolysis time 5h,pH value 7 at 65℃,and the yield of polypeptide powder is 9.31%. The best effect to make active calcium was under the below condition:soaking fish bone 6h under 20% lactic solution with the rate of m(the fishbone powder, g)：V(20％lactic acid, mL)=10g:70mL ,and the yield of calcium powder is 25.00%.
