Embodiment 1

[0024] S101: Fermenting the dark tea to obtain black tea with S. coronoidis;

[0025] S102: crushing the black tea with S. coronoidis to obtain dark tea pieces with a particle size of 2 cm;

[0026] S103: Select the black tea block with S. coronis for later use, and re-ferment the black tea block without S. coronis;

[0027] S104: Pulverize the black tea block with S. coronoidis to obtain black tea powder with a particle size of 0.1 mm;

[0028] S105: Put the black tea powder into a vibrating sieve with an aperture of 40 meshes and shake it, and re-ferment the dark tea powder retained on the vibrating sieve, and set aside the sieved mixture;

[0029] S106: Filter the mixture through a cloth net with a pore size of 60 meshes to obtain Cystis coronis.

Abstract

The invention provides a method for extracting eurotium cristatum from dark tea. The method comprises the following steps: fermenting dark tea to obtain the dark tea containing the eurotium cristatum; crushing the dark tea containing the eurotium cristatum, so as to obtain dark tea blocks; selecting the dark tea blocks containing the eurotium cristatum for later use; smashing the dark tea blocks containing the eurotium cristatum to obtain dark tea powder; tiling the dark tea powder, putting in an oscillating sieve and oscillating, wherein a sieved mixture is for later use; and filtering the mixture by a fabric net, so that the eurotium cristatum is obtained. In the method for extracting the eurotium cristatum from the dark tea, the crushed dark tea blocks containing no eurotium cristatum and the dark tea powder intercepted on the oscillating sieve after oscillating can be fermented again for preparing the dark tea containing the eurotium cristatum, cyclic utilization of the dark tea is realized, and production cost is reduced; meanwhile, the extraction method provided by the invention is simple in operation, easy to realize and low in equipment investment cost and has a relatively good application prospect.

Description

technical field [0001] The invention relates to the technical field of substance extraction, and more specifically, relates to a method and application of extracting Saccharomyces coronarii from dark tea. Background technique [0002] Cystis coronoidis, commonly known as Jinhua, belongs to the fungus of the genus Physiocystis coronoides of the family Fagenaceae. It can grow on soil, Fuzhuan tea, Cordyceps sinensis, Chinese medicine tablets and sawdust and other substrates , At present, most of the coronoids are fermented from Fuzhuan tea. S. coronoidis not only has no effect on the quality of fermented Fuzhuan brick tea, but also secretes amylase and oxidase in tea leaves, catalyzes the conversion of starch in tea leaves into simple sugars, catalyzes the oxidation of polyphenolic compounds, and changes the color of tea soup Brown-red, eliminating rough green taste, making the taste of tea more refreshing, sweet and smooth. Saccharomyces coronoidis has a strong effect of pr...
