| Abstract: | Tea polyphenol is the major physiological active component in tea, and it is generally manufactured by liquid-liquid extraction technology, using ethyl acetate as solvent from water extract of tea. This paper investigated the effect of water content of ethyl acetate on the extraction efficiency of tea polyphenol. The results indicate that according to the requirement of minimizing the production cost, the volume of water phase and solvent should be adjusted to 2:1 ratio. |
