| 利用撞击-喷射流空化协同强化大豆粕蛋白溶解。通过单因素实验、响应面实验设计优化了撞击-喷射流空化强化大豆粕蛋白溶解工艺条件，测定了撞击-喷射流空化协同强化大豆粕蛋白水溶液的表面活性。结果表明：撞击-喷射流空化协同强化大豆粕蛋白溶解的最优工艺条件为撞击-喷射流空化压力0.45 MPa、撞击-喷射流空化时间65 min、撞击-喷射流空化温度58?℃、入口角度-出口角度组合30°-40°、料液比1.5∶?100，在最优条件下大豆粕蛋白溶解度由0.780 mg/mL提高到1.737 mg/mL；撞击-喷射流空化协同强化大豆粕蛋白水溶液具有一定的表面活性。 |
| 英文摘要: |
| The action of impinging stream and jet cavitation was used to strengthen the dissolution of soy bean protein. The single factor experiment and response surface methodology were used to optimize the dissolution conditions of soybean protein by impinging stream and jet cavitation. The surface activity of soybean protein solution was also determined. The results showed that the optimal conditions were obtained as follows: impinging stream and jet cavitation pressure 0.45 MPa, impinging stream and jet cavitation time 65 min, impinging stream and jet cavitation temperature 58?℃, inlet angle-outlet angle 30°-40°, ratio of material to liquid 1.5∶?100. Under the optimal conditions, the solubility of soybean protein increased from 0.780 mg/mL to 1.737 mg/mL. The water-soluble soybean meal protein prepared by impinging stream and jet cavitation had certain surface activity. |
