Embodiment 1

[0015] According to the mass percentage, mix 95% ripe Pu-erh tea with 5% large-leaf sun-dried green tea, coarsely crush them, and put them into the extraction tank; put 5 times the quality of the tea into edible ethyl acetate, extract at room temperature for 6 hours, and filter Take out the extract, depressurize or vacuum concentrate at room temperature, further vacuum dry and reclaim ethyl acetate to obtain extract 1; drop into the extraction tank with a concentration of 95% (volume ratio concentration) of edible alcohol that is 10 times the quality of tea leaves, at room temperature extract at low temperature for 3 hours, filter the extract, concentrate under reduced pressure or vacuum at room temperature, and further vacuum dry to recover the alcohol to obtain extract 2; extract the tea material extracted with ethyl acetate and edible alcohol with a carbon dioxide supercritical extraction device, extract The liquid is concentrated to a density of 1.1 g / ml by a reverse osmosi...

Embodiment 2

[0017] According to the mass percentage, use 50% ripe Pu-erh tea and 50% raw Pu-erh tea as raw materials, coarsely crush them, put in edible ethyl acetate twice the quality of tea leaves, extract at room temperature for 4 hours, filter out the extract, and store at room temperature Under reduced pressure or vacuum concentration, further vacuum drying to reclaim ethyl acetate, to obtain extract 1; put into the extraction tank 5 times the concentration of tea leaves in an aqueous edible alcohol solution of 99% (volume ratio concentration), and extract at room temperature for 6 hours , filter out the extract, depressurize or vacuum concentrate at room temperature, further vacuum dry to recover alcohol, and obtain extract 2; the following steps obtain the Pu’er tea extract according to the method in Example 1, except that after supercritical extraction with carbon dioxide, the extract is obtained by freezing Drying method to obtain tea powder. According to the mass ratio of Pu'er ...

Embodiment 3

[0019] According to the mass percentage, use 70% ripe Pu-erh tea and 30% green tea as raw materials, coarsely crush, put 10 times the quality of the tea leaves into edible ethyl acetate, extract at room temperature for 1 hour, filter out the extract, and depressurize at room temperature Or vacuum concentration, further vacuum drying to reclaim ethyl acetate, to obtain extract 1; drop into the extraction tank with an aqueous edible alcohol solution whose concentration is 90% (volume ratio concentration) twice of the tea quality, extract at room temperature for 1 hour, and filter out The extract is concentrated under reduced pressure or vacuum at room temperature, further vacuum-dried to recover the alcohol, and extract 2 is obtained; the following steps are followed to obtain the Pu-erh tea extract according to the method in Example 1, except that after supercritical extraction with carbon dioxide, the method is freeze-dried Get tea powder. According to the proportioning of 80%...

Abstract

The invention relates to a Pu,er tea health-care food and a preparation method thereof. The preparation method comprises the following steps of: blending a fermented Pu,er tea with a dried primary tea, a raw tea and a green tea to form a raw material; and using various edible solvents such as water, alcohol, ethyl acetate and the like to perform continuous extraction so as to ensure that the components such as tea polyphenol, tea pigment, theanine, tea polysaccharide and the like in the Pu,er tea are used comprehensively. The entire extraction process comprises the extraction, filtering, condensing, drying and sterilizing which are finished at a lower temperature or close to the room temperature so as to avoid damages to functional components of the Pu,er tea in the traditional high-temperature preparation process. Simultaneously, the Pu,er tea health-care food has a high yield, a low cost and good stability, and is suitable for large-scale production. The functional components extracted from the tea raw materials can be prepared into various health-care food forms such as capsules, soft capsules, tablets, granules and the like.

Description

technical field [0001] The invention relates to the technical field of food, in particular to a Pu'er tea health food and a preparation method thereof. Background technique [0002] Pu'er tea is a large-leaf tea produced in the Lancang River Basin, including Lincang, Pu'er, and Xishuangbanna in Yunnan. Because the distributing center is in Pu'er County, Yunnan Province, it is named Pu'er Tea. Pu-erh tea can be divided into cooked tea and raw tea. Ripe tea is fermented tea and raw tea is unfermented tea. Raw Pu-erh tea soup has a strong orange-yellow color. Its aroma is sharp and long-lasting. Ripe Pu-erh tea is unique in quality, dark in color, rich in aroma, mellow and sweet in taste, and has endless aftertaste after drinking. [0003] Pu'er tea can quench thirst, promote body fluids and refresh oneself, and has a significant effect on removing excess fat in the human body. There have been a lot of researches on the efficacy of Pu'er tea at all times and in all over the...
