摘　　要：蛋白酶和蛋白质混合液经微波辐射―蛋白酶解反应器的微波辐射后,可以大大缩短酶解时间和减少蛋白酶和蛋白质的消耗量。设计微波辐射-蛋白酶反应器,通过单因素和正交设计试验,微波辅助蛋白酶水解大豆蛋白的工艺条件:固液比是1∶8(g/mL)、蛋白酶用量5%、微波功率480 W、微波辐射时间60 min、酶解温度55℃。After the microwave radiation of the mixed liquid of the protease and the protein, It can greatly re-duce the time of enzymatic hydrolysis and reduce the consumption of protein and protease. In this paper, we de-signed a microwave radiation protease reactor. Through single factor andorthogonaldesignexperiment, using sin-gle-factor test and orthogonal test, preparation technology wasoptimized：the ratio of solid-liquid 1：8（g/mL）, the contend of papayin 5%, 480 W microwave radiation, 60 min-hydrolysis experiment ,the temperature of hydrolysis 55℃.
