| 摘 要： | 利用逐因子试验和Box-Behnken试验对黑豆皮中红色色素萃取工艺进行了优化研究,获得了工艺优化的数学模型y=3.85+0.43x1+0.05x2-0.32x3-0.12x1x2+0.063x1x3+1.0E-0.02x2x3-0.58x12-0.49x22-0.34x32,分别对自变量求偏导得到优化工艺条件:x1=0.346,x2=0.006988,x3=-0.44,通过转换得到实际工艺条件,即萃取温度X1=83.46℃、萃取时间X2=30.07 m in、料液比X3=1:35.6(w/v)。在最优化条件下模型预测OD512为3.997,验证试验结果为3.85±0.01(n=3),试验证明,逐因子试验和Box-Behnken试验联用可以很好的应用于黑豆皮红色色素的萃取工艺中。
