Problems solved by technology

In the above step of separating the tea saponin extract, a considerable part of the tea dregs particles along with the tea saponin extract flows into the next filter part, and a considerable part of the tea dregs particles often cause the outlet to be blocked, resulting in the separation of the tea saponin extract. difficulty

Embodiment 1

[0010] Embodiment 1: the method for extracting tea saponin in Camellia oleifera seed dregs, with hydrous ethanol as extraction solvent, comprises the following steps:

[0011] a. Put the Camellia oleifera seed meal into a turbo grinder, and pulverize the Camellia oleifera seed meal to a fineness of 30 meshes;

[0012] b. Put the pulverized camellia seed meal into the leaching tank, and inject ethanol into the leaching tank when the temperature in the leaching tank reaches 25°C. The volume concentration of ethanol is 65%, and the mass ratio of camellia oleifera seed meal to ethanol is 1 :10, heat up to 90°C, make ethanol reflux, after 2.5 hours of stirring and ethanol reflux state, extract the leaching solution from the bottom of the leaching tank, filter and inject it into the enamel kettle for temporary storage;

[0013] c. Add ether in the enamel kettle, the mass ratio of ether to the leaching solution is 1:3, so that the tea saponin in the leaching solution is precipit...

Embodiment 2

[0014] Example 2. The method for extracting tea saponin in Camellia oleifera seed dregs, with hydrous ethanol as extraction solvent, it comprises the following steps:

[0015] a. Put the Camellia oleifera seed meal into a turbo grinder, and pulverize the Camellia oleifera seed meal to a fineness of 45 meshes;

[0016] b. Put the pulverized camellia seed meal into the leaching tank, and inject ethanol into the leaching tank when the temperature in the leaching tank reaches 27°C. The volume concentration of ethanol is 65% to 75%. The mass ratio is 1:10, the temperature is raised to 92°C, and the ethanol is refluxed. After 3 hours of stirring and ethanol reflux, the leaching solution is extracted from the bottom of the leaching tank, filtered and injected into an enamel kettle for temporary storage;

[0017] c. Add diethyl ether in the enamel kettle, the mass ratio of diethyl ether to the leaching solution is 1:3.3, so that the tea saponin in the leaching solution is precip...

Abstract

The invention relates to a method for extracting tea saponin from tea seed meal, which comprises the following steps of: a, putting the tea seed meal into a turbine crusher and crushing the tea seed meal into the fineness of 30 to 50 meshes; b, putting the crushed tea seed meal into a leaching tank, injecting 65 to 75 volume percent ethanol into the leaching tank in a mass ratio of the tea seed meal to the ethanol of 1:10 when the temperature in the leaching tank is between 25 and 30 DEG C, raising the temperature to between 90 and 95 DEG C so as to reflux the ethanol, stirring for 2 to 3 hours, extracting leaching solution from the bottom of the leaching tank in a refluxing state of the ethanol, filtering, and injecting the solution into an enamel kettle for temporary storage; and c, adding ethyl ether into the enamel kettle in a mass ratio of the ethyl ether to the leaching solution of 1:3-3.5 to ensure that the tea saponin in the leaching solution is a flocculent precipitate, and extracting the flocculent precipitate and drying to prepare the finished tea saponin. The method has the advantages that: the method effectively improves the leaching rate of the tea saponin in a solvent; and the tea saponin leaching solution can be smoothly extracted and a blockage phenomenon is completely avoided in the step of separating the tea saponin leaching solution.

Description

technical field [0001] The invention relates to a method for extracting tea saponin from camellia oleifera seed dregs. Background technique [0002] Tea saponin is a kind of pure natural non-ionic surfactant, which is a kind of glycoside compound extracted from the seeds of Camellia, which widely exists in various tea plants. Its basic mechanism includes ligand, sugar body and organic acids. Tea saponin has the general properties of saponins, bitter and spicy. [0003] In the prior art, a polar solvent is used to extract tea saponin from camellia oleifera seed dregs. The technological process is as follows: soak the pulverized tea dregs in an aqueous polar solvent in a leaching tank to extract tea saponin, tea saponin The extract is separated from the tea dregs, and the tea saponin extract is filtered and concentrated to obtain a crude product of tea saponin. In the above process, the tea meal raw material is generally crushed to particles with a particle size larger than...
