摘要
研究了在稀碱条件下玉米胚蛋白的浸提工艺。通过中心组合设计及响应面分析(RSA),建立了预测蛋白质浸出率的数学模型,优化了蛋白质的浸提工艺。结果表明:在最佳浸提条件水料比11 mL/g、pH值8.7、温度46℃,浸提90 m in,玉米胚蛋白浸出率可达58.46%。
The technology for protein extraction from defatted corn germ with thin alkaline solvent was studied. Mathematical model for predicting the extraction rate of protein was set up by central composite design and response surface analysis （RSA）, and the extraction technology was optimized. The results show that optimum conditions of extraction are： ratio of water to material of 11mL/g, pH value of 8. 7, the temperature of 46℃. The rate of extraction reached 58. 46% at above-mentioned conditions for 90 min.
