Abstract: In this study,the extraction technology of bone protein of pig was studied.At first the fat was removed by petroleum ether with the method of reflux at low temperature.Then the bone protein of pig was extracted after decalcification and alkali treatment.This experiment investgated the influence of decalcification conditions on the result and the optimum conditions of extraction was determined.The experimental results indicated that the best acid dipping condition is hydrochloric acid concentration 0.72 mol/L,solid-liquid ratio 1:10 and dipping time 8 h.And the optimum conditions of extraction are extraction time 7 h,matter to solvent =1:8,pH value 4,and temperature 100℃.

Key words: bone protein of pig, decalcification, extraction
