2、液比之間存在顯著的交互作用。對(duì)多元二次回歸方程進(jìn)行求偏導(dǎo),可以得到:l,=1.060.013曰一6.5A+0.84C:l,=O.19一O.013A一0.42口+0.73C;y=0.60+O.84A+O.73日一3.92C聯(lián)立方程組,解得熱水浸提香菇多糖最優(yōu)條件的編碼值如下:A=0.138,B=0.002,C=0.169。即在浸提溫度為78.6,浸提時(shí)間為120min,料液比為l:58.3時(shí),模型預(yù)測(cè)香菇粗多糖得率最大值為14.12%。3結(jié)論通過(guò)BoxBenhnken設(shè)計(jì)和響應(yīng)面分析法,利用DesignExperc統(tǒng)計(jì)軟件能夠可靠地進(jìn)行優(yōu)化實(shí)驗(yàn)以及數(shù)據(jù)處理。本實(shí)驗(yàn)應(yīng)用這一方法對(duì)香菇多糖提取的工藝
