摘　　要： 为避免保健酒的后浑浊,提高其澄清度和稳定性,采用膜过滤的方法,对中空纤维膜澄清保健酒的工艺进行了研究。实验选用压力、料液流速和温度为自变量,保健酒透光率和膜通量为响应值,采用Box-Benhnken设计的方法,拟合得到二次多项式回归方程的预测模型,并确定中空纤维膜澄清保健酒的最优条件为:压力0.1MPa,料液流速1.5L/min,温度37.4℃。在此条件下,酒液透光率为87.65%,膜通量为42mL/min,并且色泽得到明显改善,pH、电导率、酒精度以及主要有效成分总皂甙的变化不大。 In order to improve the clarity and stability of healthy wine, the clarification technology of healthy wine filtrated by through hollow fiber membrane was studied. Based on single factor experiments, the pressure, liquid flow rate and temperature were selected as independent variables, and the transmittance and membrane flux of healthy wine were selected as response values.The quadratic polynomial regression equation predictive model was obtained by Box-Benhnken design.The optimum conditions were acquired that pressure was 0.1 MPa, the liquid flow rate was 1.5 L/min and the temperature was 37.4%. Under these conditions, the transmittancy of healthy wine was 87.65% and the membrane flux was 42mL/min.Besides,the absorbance of healthy wine was reduced and the color was improved.Its pH,conductivity and the content of alcohol changed a little and saponins as the main active ingredient was retained.
