摘要: 研究了响应面法超滤提纯无梗五加果多糖工艺。在单因素实验的基础上,利用minitab15软件设计了响应面实验。研究了超滤压力,超滤时间,超滤温度,料液浓度对超滤膜通量的影响并确定最佳工艺参数。结果表明超滤压力0.30 MPa,超滤时间10min,超滤温度40℃,料液浓度1.8mg/mL,预测超滤膜通量达到理论值最高0.077 mL/cm2?min,实际膜通量值为0.070 mL/cm2?min,与预测值基本相符。

Abstract: The ultrafiltration technology of separating polysaccharide from Acanthopanax sessiliforous fruits was studied. On the basis of single factor tests, response surface methodology was designed by minitab software 15. The effect of ultrafiltration pressure, time, temperature and feeding concentration on membrane flux was studied. The results showed that the optimum ultrafiltration conditions were ultrafiltration pressure of 0.30MPa, ultrafiltration time of 10min, ultrafiltration temperature of 40℃ and feeding concentration of 1.8mg/mL.The practical membrane flux was 0.070 mL/cm2?min,close to the predicted membrane flux of 0.077 mL/cm2?min.
