以低温浸出橡胶籽粕为原料,通过超声波辅助提取橡胶籽粕中蛋白。在单因素试验结果的基础上,选取提取温度、液料比、超声功率和碱溶pH 4个因素进行Box-Behnken响应面法试验设计,以粗蛋白的提取率为响应值,对提取工艺参数进行优化。在提取时间为60 min时,橡胶籽粕蛋白最佳提取工艺为超声功率315W、提取温度52℃、液料比46∶1（m L/g）、碱溶pH 10、酸沉pH 4.5的条件下,橡胶籽粕蛋白的提取率为82.51%。

Using rubber seed meal extracted at low temperature as raw matenial, protein extracted by ultrasonic assisted was studied. On the basis of single factor experiments, extraction temperature, ratio of liquid to material, ultrasonic power and alkali soluble pH were studied by Box-Behnken response surface experimental. With crude protein extraction yield as the response value, the process was optimized.When the extraction time was 60 min, the best extraction process of rubber seed meal protein was ultrasonic power 313 W, extraction temperature 52 ℃...
