| titleOfInvention | Separation method for improving yield of tea saponin |
| abstract | The invention discloses a separation method for improving the yield of tea saponin. The separation method comprises the following steps: s1, directly crushing the camellia seed kernels without tea oil removal, then extracting with an ethanol solution with the mass fraction of more than 80%, separating to obtain a tea saponin ethanol solution, and concentrating to obtain a tea saponin aqueous solution; s2, mixing the aqueous solution of the tea saponin obtained in the step S1 with butyl acetate according to the volume ratio of 1: 0.05-2, adjusting the pH value of the mixed solution to 1-3 by adopting hydrochloric acid, and standing to obtain a tea saponin coagulum; and S3, adding the coagulum obtained in the step S2 into a 0.2-1% hydrochloric acid solution according to a ratio of 1: 1-10, stirring, separating to obtain a solid, and drying to obtain the tea saponin. The method can simply and quickly obtain the tea saponin from the aqueous solution of the tea saponin, and the yield of the tea saponin is higher and is 38.3 percent. Meanwhile, the method has the advantages of simple process, simple operation, high tea saponin separation speed and low cost, and is suitable for large-scale industrial preparation of tea saponin. |
