Embodiment 1

[0099] The preparation of embodiment 1 Pu'er tea extract, wherein each component accounts for the percentage by weight of extract gross weight:

[0100] Tea polyphenols: 35.95%

[0101] Theabrownin: 24.87%

[0102] Caffeine: 9.80%

[0103] Tea polysaccharide: 25.21%.

[0104] Take Pu'er tea, add water to vigorously boil and decoct for 3 times, each decocting time is 4 hours, the total multiple of adding water is 22 times, the first time is 8 times, the second time is 8 times, the third time is 6 times, the extraction solution Pass through a 60-mesh sieve, cool the filtrate to 45°C naturally, and filter it with a 200,000 molecular weight filter membrane to obtain the membrane filtrate and membrane retentate; concentrate the membrane retentate under reduced pressure at a temperature of ≤70°C to obtain a concentrated 10% solid content Liquid and concentrated liquid are centrifuged for the first time with a three-legged centrifuge, and the centrifuged liquid for the first time ...

Embodiment 2

[0105] Example 2 Take Pu’er tea, add water to vigorously boil and decoct to extract 3 times, each decocting time is 2 hours, the total multiple of adding water is 26 times, the first time is 8 times, the second time is 8 times, the third time is 10 times , the extract is passed through a 80-mesh sieve, the filtrate is naturally cooled to 45°C, and filtered with a 100,000 molecular weight filter membrane to obtain a membrane filtrate and a membrane retentate; the membrane retentate is concentrated under reduced pressure at a temperature of ≤70°C to obtain a solid content of 10 % concentrated solution, the concentrated solution is centrifuged for the first time with a three-legged centrifuge, and the centrifuged liquid for the first time is centrifuged for the second time with a tubular centrifuge. Concentrate under reduced pressure separately or in combination, concentrate to 60°C and measure the specific gravity of 1.14, and spray dry.

Abstract

The invention relates to an extractive of the traditional Chinese medicine and preparation thereof, in particular to the extractive of Pu'er tea and the preparation method thereof; wherein the preparation method comprises the technical means such as water 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...
