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。在单因素实验结果的基础上,采用Box-Behnken响应面法实验设计,以橡胶籽粕中提取的粗蛋白的提取率为响应值,对其提取工艺参数进行优化。在提取时间为60 min时,橡胶籽蛋白最佳提取工艺为超声功率315 W、提取温度48℃、液料比16∶1（mL/g）、碱溶pH10,然后在pH值为4.5进行酸沉沉淀,此条件下橡胶籽粕蛋白质的提取率达76%。

The protein was extracted from rubber seed meal by ultrasonic extraction with low temperature leaching rubber seed meal as raw material.Based on the results of single factor experiment,Box-Behnken response surface experiment was used to optimize the extraction parameters of crude protein extracted from rubber seed meal as the response value.The optimum extraction process of rubber seed protein is ultrasonic power 315 W,extraction temperature 48 ℃,liquid ratio 16∶1（mL/g）,alkali pH10,and then acid precipitation at pH4.5.Under this...
