【摘要】 以白果为原料,在单因素实验的基础上采用响应面分析法研究白果蛋白质的提取工艺,考察提取液浓度、p H、料液比及提取时间对白果蛋白质提取率的影响。结果表明白果提取蛋白质的最适条件为:提取液浓度0.16 mol/L,p H8.7,料液比1∶26,提取时间5 h,此条件下,白果蛋白质的提取率为82.76%,与理论预测值83.01%相比,其相对误差为0.30%,说明优化得出的回归模型具有一定的实际指导意义。更多还原

【Abstract】 The response surface analysis method was used to study the Ginkgo protein extraction process on the basis of single factor experiment with Ginkgo for materials,the effect of Tris-HCl concentration,p H,solidliquid rate,extraction time on the protein extraction yield was inspected. The research results showed that the optimal conditions for ginkgo protein extraction:0.16 mol/L,p H8.7,1∶26(g/m L),and 5 h. Under this condition,the yield of Ginkgo protein was 82.76%,compared to the theoretical value,the relative error of 0.30%. Optimized regression equation derived some practical significance.更多还原
