| 摘 要： | 研究了浓度、温度、压力各因素对截留分子量100k超滤膜澄清分离速溶茶副产品中茶多酚的影响,并采用正交试验设计优化了超滤膜澄清分离的工艺条件.结果表明,在样液质量分数0.40%、温度35℃、压力0.138 MPa的条件下分离试样,膜透过液中茶多酚含量达48.73%,得率为40.75%,说明超滤技术是澄清分离速溶茶副产品中茶多酚的有效手段之一.

| Abstract: | The operational conditions were studied and discussed.The best operational conditions of 100k UF membrane were as follows: concentration 0.40%,temperature 35 ℃,pressure 0.138 MPa.At the optimal conditions,the content of tea polyphenols was 48.73%,final yield of tea polyphenols was 40.75%.The results showed it was feasible to separate tea polyphenols from instant tea by-product by ultrafiltration. |
