【摘要】：采用中心組合設計(CCD)響應面法(RSM)優(yōu)化α淀粉酶抑制劑篩選條件.在單因素試驗基礎上,對影響α淀粉酶抑制劑活性的4個因素即淀粉溶液濃度、保溫溫度、DNS用量、沸水時間進行優(yōu)化,根據(jù)回歸方程最終確定α淀粉酶溶液質量濃度1mg/mL,淀粉溶液質量濃度17 mg/mL,保溫溫度46℃,保溫時間15 min,DNS用量2mL,沸水時間6min.經(jīng)試驗驗證結果穩(wěn)定可靠,可用于α淀粉酶抑制劑篩選.
[Abstract]:On the basis of single factor test , four factors influencing the activity of 偽 amylase inhibitor , i.e . the concentration of starch solution , the temperature of heat preservation , the amount of DNS and the time of boiling water , were optimized . The concentration of 偽 amylase was determined to be 1mg / mL , the mass concentration of starch was 17 mg / mL , the temperature was 46 鈩，
