Abstract: In this study, bone fragments were chosen as raw material. The influence of high-temperature and high-pressure technology on the extraction rate of bovine bone protein were evaluated. Single factors and response surface methodology was used to optimize extraction of bovine protein by using high-temperature and high-pressure technology. The main parameters including the material-fluid ration, extract time and extract temperature, and the extraction rate of protein were the evaluation index. The research results showed that the optimum conditions of extraction are as follows: material-fluid ration is 1:4, extract time is 4 h and extract temperature is 133 ℃. Under the optimal extraction condition, the extraction rate of bovine bone protein was 64.73%.
