Embodiment 1

[0035] A preparation method of Fuling Liubao tea, comprising the steps of:

[0036] (1) Preparation of Poria cocos decoction pieces: select fresh and pest-free Poria cocos whole roots, wash and dry, cut into thin slices with a thickness of 0.5-1 mm, and spread them in the sun until the water content is 8%, to obtain Poria cocos decoction pieces;

[0037] (2) Poria cocos decoction pieces were broken: freeze the Poria cocos decoction pieces in liquid nitrogen at -196°C for 3 minutes, quickly take them out and put them into a cell wall breaking machine, and perform wall breaking treatment at a speed of 30,000 rpm for 3 minutes to obtain broken Poria cocos Powder, its wall breaking rate is 94%;

[0038] (3) Preparation of Poria cocos extract: Mix the broken Poria cocos powder and water at a mass ratio of 1:18, heat to boiling on high heat, decoct on low heat for 0.5 h, filter to obtain the filtrate, and concentrate by rotary evaporation at 80°C and -0.09 MPa , to obtain a concent...

Embodiment 2

[0046] A preparation method of Fuling Liubao tea, comprising the steps of:

[0047] (1) Preparation of Poria cocos decoction pieces: select fresh and insect-free Poria cocos whole roots, wash and dry, cut into thin slices with a thickness of 2-3 mm, and spread them in the sun until the water content is 5%, to obtain Poria cocos decoction pieces;

[0048] (2) Poria cocos decoction pieces were broken: freeze the Poria cocos decoction pieces in liquid nitrogen at -196°C for 1 min, quickly take them out and put them into a cell wall breaking machine, and perform wall breaking treatment at a speed of 20,000 rpm for 1 min to obtain broken Poria cocos Powder, its wall breaking rate is 91%;

[0049] (3) Preparation of Poria cocos extract: Mix the broken Poria cocos powder and water at a mass ratio of 1:15, heat to boiling on high heat, decoct on low heat for 1 hour, filter to obtain the filtrate, and concentrate by rotary evaporation at 90°C and -0.08 MPa , to obtain a concentrated s...

Embodiment 3

[0057] A preparation method of Fuling Liubao tea, comprising the steps of:

[0058] (1) Preparation of Poria cocos decoction pieces: select fresh and insect-free Poria cocos whole roots, wash and dry, cut into thin slices with a thickness of 0.5-2 mm, and spread them in the sun until the water content is 6%, to obtain Poria cocos decoction pieces;

[0059] (2) Poria cocos decoction pieces were broken: freeze the Poria cocos decoction pieces in liquid nitrogen at -196°C for 5 minutes, quickly take them out and put them into a cell wall breaking machine, and perform wall breaking treatment at a speed of 25,000 rpm for 3 minutes to obtain broken Poria cocos Powder, its wall breaking rate is 88%;

[0060] (3) Preparation of Poria cocos extract: Mix the broken Poria cocos powder and water at a mass ratio of 1:15, heat to boiling on high heat, decoct on low heat for 1 h, filter to obtain the filtrate, concentrate by rotary evaporation at 70°C and 0.1 MPa, Obtain the concentrated so...

Abstract

The invention relates to a preparation method of poria cocos Liupu tea. The preparation method comprises nine steps of poria cocos decoction piece preparation, poria cocos decoction piece wall breaking, poria cocos extraction liquid preparation, strain activation, raw tea fixation, pile fermentation, secondary fermentation, natural aging and drying shaping. The poria cocos is subjected to wall breaking to extract active ingredients; the wall breaking rate is 85 to 94 percent; the extraction efficiency of wolfiporia cocos triterpenes, pachman and poria cocos sterol can be effectively improved;the extraction time is shortened; the effective ingredient damage is avoided; the fermentation strains including eurotium cristatum, blue mould, aspergillus niger, yeast and mucor are extracted from Liupu tea; the Liupu tea flavor lack due to addition of single strain for fermentation can be avoided; the fermentation strains are activated and are then inoculated; the activity of the fermentation strains can be favorably improved; the fermentation efficiency of the Liupu tea can be improved; through the pile fermentation, secondary fermentation and aging, the golden flower growing effect is good; the nutrition ingredients of Liupu tea and poria cocos can be adsorbed and converted in the fermentation process; health care ingredients such as chitin, chitin chitosan, beta-polyglycoside, cellulose and glycoprotein are generated.

Description

technical field [0001] The invention belongs to the field of tea processing biotechnology, and in particular relates to a preparation method of Fuling Liubao tea. Background technique [0002] Liubao tea has the characteristics of "red, thick, old and mellow". The top-grade tea has betel nut fragrance and golden flower. It has outstanding weight loss effect and can improve the symptoms of energy metabolism. The effect of diuresis and detoxification is well-known in Guangdong, Guangxi, Hong Kong, Macao, Southeast Asia and other domestic and foreign markets. [0003] The basic production process of traditional Liubao tea is greening, rolling, fermenting, drying, steaming, fermenting, drying, steaming, pressing and aging. During the rolling process of Liubao tea, the leaf cells are broken, various enzymes fully contact with the substrate, and undergo chemical pre-action to form complex complexes. During the stacking process, microorganisms grow vigorously under the action of ...
