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%.
