研究葵花籽粕蛋白质盐提法提取最佳工艺。在单因素试验的基础上，选取NaCl浓度、提取温度和料液比为自变量，以蛋白质提取率为响应值，利用响应面法对葵花籽粕蛋白质的提取工艺进行优化，得到回归方程的预测模型，该模型能较好的反映各因素与响应值之间的关系。最佳提取工艺条件为，NaCl浓度1.51 mol/L、料液比1∶12.88（g/mL）、提取温度60.27℃。在此条件下，蛋白质的提取率为36.64%。“,”To study the extraction technology of protein from sunflower meal using salt extraction. Based on the single-factor test,the extraction factors of NaCl concentration,extraction temperature and water/dry ratio were optimized using the response surface methodology with the extraction rate of protein as the response value. As a result ,the optimum extraction conditions of protein from sunflower meal were 1.51 mol/L of NaCl concentration , 1∶12.88 (g/mL) of dry/water ratio,60.27℃of extraction temperature. Under these conditions,the extraction rate of chlorogenic acid was 36.64%.
