摘要
介绍了一种乙醇———离子关合沉淀法制备茶多酚的新工艺，并对工艺过程进行优化。在最佳工艺条件下，茶多酚的收率可达到１２．１％，纯度达９２．３％。同时初步探讨了乙醇———离子联合沉淀法除果胶类物质的机理。
In this paper,a new method for the preparation of tea polyphenol is introduced.The optimal conditions are obtained under which the yield and purity reach 12.1% and 92.3% respectively. The mechanism on the removal of pectin and protein from tea polyphenol is correspondingly studied.
