| Abstract: | Tea saponin in water after aqueous enzymatic extraction was purified by membrane technology.The results showed that:through removing impurity using the microfiltration membrane of 300 nm under pH value of 5.5,saponin content increased from 2.84% to 11.09% with the loss rate of 9.12%,through concentrating using nanofiltration membrane of 500 Da,saponin content increased from 3.57% to 15.30% with the loss rate of 13.7%,through drying at 55 ℃,normal pressure,the tea saponin with purity of 91.01% was obtained. |
