摘要
通过单因素实验和响应曲面法,优化了从玉米黄粉浓缩蛋白中超声醇提玉米醇溶蛋白的工艺,超声醇提玉米醇溶蛋白的最佳工艺条件为:温度50℃、时间70m in、乙醇浓度70%、pH12、料液比(g/mL)1∶8。该条件下玉米醇溶蛋白提取率为45.03%,纯度达到92.60%。
Optimized ultrasonic alcohol extraction of zein from corn gluten meal concentrated protein by monofactor experiment and response surface methodology. The results showed that the ratio of solid to liquid 1:8, ethanol content was 70%, pH 12 and ultrasonic temperature was 50℃ for 70min. Under this condition,the yield of zein reached 45.03%, and the purity was 92.60%.
