| 摘 要： | 采用响应面法优化酒糟中蛋白质的提取条件.在单因素实验的基础上,选取醇碱比、固液比、提取时间为影响因子,应用Box-Behnken中心组合进行3因素3水平的实验设计,以蛋白质提取率作为响应值,进行响应面分析.结果表明,酒糟中蛋白质最佳提取条件为:提取时间87.2min,固液比(g/mL)为1:42.3,醇碱比为1:2.7,提取率预测值19.57%,验证值19.40%,与预测值的相对误差0.88%.

| Abstract: | The response surface analysis methodology (RSM) was used for optimizing extraction conditions in the extraction process of grains protein.Based on the single-factor experiments,three independent variables,alcohol to alkali ratio,solid to liquid ratio and extracting time were selected as casual factors for the extraction.The experiments were carried out according to Box-Behnken central composite experiment design.Response surface analysis method was applied to determining the effect of central composite expe... |
