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: 18.97%

[0095] Theabrownin: 15.87%

[0096] Caffeine: 44.83%

[0097] Tea polysaccharide: 12.45%

[0098] Take superfine puer tea powder, add water and extract at 95°C for 3 times, the multiple of water is 14 times, and the extraction time is 2 hours; the process of extraction and discharge is continuously stirred, and the extracted slurry is centrifuged with a three-legged centrifuge each time. Combine the centrifugate, the centrifugate is naturally heated to 50°C, and the 200,000 molecular weight membrane is filtered to obtain the membrane filtrate and the membrane retentate; when the temperature is ≤70°C, the membrane retentate is concentrated under reduced pressure to a concentrated solution with a solid content of 10%. Use a three-legged centrifuge to centrifuge once, and use a tube centrifuge to cent...

Embodiment 2

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

[0100] Take superfine puer tea powder, add water and extract at 95°C for 3 times, the multiple of water addition is 16 times, and the extraction time is 2 hours; during the extraction and discharge process, it is continuously stirred, and the extraction slurry is centrifuged with a three-legged centrifuge each time. Combine the centrifugate, the centrifugate is naturally heated to 40°C, and the 300,000 molecular weight membrane is filtered to obtain the membrane filtrate and the membrane retentate; when the temperature is ≤70°C, the membrane retentate is concentrated under reduced pressure to a concentrated solution with a solid content of 10%. Use a three-legged centrifuge to centrifuge once, and use a tubular centrifuge to centrifuge the first centrifuge for the second time. The temperature is ≤70°C. Combine the membrane filtrate and the second centrifuge and concentrate to a specific gravity of 1.13 / 55°C. The concent...

Embodiment 3

[0145] Embodiment 3, the preparation of Pu'er tea extract

[0146] Take superfine puer tea powder, add water and extract once at 75°C, add water 10 times, and extract for 1 hour; continuously stir during the extraction and discharge process, and centrifuge each extraction slurry with a three-legged centrifuge. Merge the centrifugate, the centrifuge is naturally heated to 30°C, and filtered by a 100,000 molecular weight membrane to obtain the membrane filtrate and the membrane retentate; the temperature is ≤70°C, and the membrane retentate is concentrated under reduced pressure to a concentrated solution with a solid content of 5%. Use a three-legged centrifuge to centrifuge once, and use a tubular centrifuge to centrifuge the first centrifuge for the second time. The temperature is ≤70°C. Combine the membrane filtrate and the second centrifuge and concentrate to a specific gravity of 1.01 / 55°C. The concentrated paste can be spray-dried. .

Abstract

The invention relates to a traditional Chinese medicinal extract and a preparation method thereof, in particular to a puerh tea extract and preparation thereof. The preparation method comprises the technical means of water extraction, membrane filtration, centrifugation, condensation, filtration, 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...
