Embodiment 1

[0093] The preparation of embodiment 1 Pu'er tea extract, wherein each component accounts for the percentage by weight of extract gross weight:

[0094] Tea polyphenols: 50.15%

[0095] Tea polysaccharide: 16.37%

[0096] Caffeine: 7.60%

[0097] Theabrownin: 23.21%.

[0098] Take Pu-erh tea, pour into groups for countercurrent circulation extraction, each group consists of 3 cans; each can is boiled and decocted for 4 extractions, each time adding 6 times of water, and each extraction time is 1h; the first extraction of each can enters the liquid storage tank , the subsequent extraction solution of each tank is used as the extraction solvent of the next tank in turn; the tank that completes the extraction is added with new raw materials and enters the cycle to start a new extraction. The extract is filtered and the extract is filtered at 80 mesh. 10,000 molecular weight membrane filtration to obtain membrane filtrate and membrane retentate; the membrane retentate is concen...

Embodiment 2

[0099] The preparation of embodiment 2 Pu'er tea extracts,

[0100] Take Pu-erh tea, pour into groups for countercurrent circulation extraction, each group is composed of 2 cans; each can is boiled and decocted for extraction 3 times, each time adding 5 times of water, and each extraction time is 0.5h; the first extraction of each can enters the storage solution The subsequent extraction solution of each tank is used as the extraction solvent of the next tank in turn; the tank that has completed the extraction is added with new raw materials and enters the cycle to start a new extraction. Filtration of the extract The extract was filtered with 60 meshes, the filtrate was naturally cooled to 30°C, and filtered through a membrane with a molecular weight of 100,000 to obtain the membrane filtrate and membrane retentate; the membrane retentate was concentrated under reduced pressure at a temperature ≤70°C to obtain a solid content of 5 % concentrated solution, the concentrated sol...

Embodiment 3

[0144] Embodiment 3, the preparation of Pu'er tea extract

[0145] Take Pu-erh tea, pour into groups for countercurrent circulation extraction, each group is composed of 5 cans; each can is boiled and decocted for 8 extractions, each time adding 3 times of water, and each extraction time is 1.5h; the first extraction of each can enters the storage solution The subsequent extraction solution of each tank is used as the extraction solvent of the next tank in turn; the tank that has completed the extraction is added with new raw materials and enters the cycle to start a new extraction. Filtration of the extract The extract is filtered through 300 meshes, the filtrate is cooled to 55°C by heat exchange, and filtered through a membrane with a molecular weight of 300,000 to obtain the membrane filtrate and the membrane retentate; the membrane retentate is concentrated under reduced pressure at a temperature ≤70°C to obtain a solid content of 30% concentrated liquid, the concentrated...

The preparation method comprises the following technical means: encapsulation, countercurrent extraction, membrane filtration, centrifugation and the like.

Description

technical field [0001] The invention relates to a traditional Chinese medicine extract and its preparation, in particular to an extract of Pu'er tea and its preparation. Background technique [0002] Pu'er tea is a famous local tea unique to Yunnan. There are two series of large-leaf sun-dried green tea from Yunnan and its reprocessing: raw Pu-erh tea that is directly processed into finished products, and cooked Pu-pu tea that is processed after artificial accelerated fermentation. There are two types of pressed tea; after the finished product, the natural aging process continues, and it has the unique quality of getting better with age. Pu-erh tea is made from the fresh leaves of the fine variety Yunnan big-leaf species, also known as Pu-erh loose tea. Its shape is thick and fat, and its color is black or brownish red, commonly known as pig liver color. The taste is mellow and sweet, with a unique aged fragrance, and has the reputation of "beauty tea". [0003] Pu-erh t...
