preparation example Construction

[0068] Specifically, in one aspect, the present invention provides a method for preparing Pu'er tea products, comprising the following steps:

[0069] (1) extract tea raw material, obtain extract;

[0070] (2) centrifuging the extract to obtain a centrate;

[0071] (3) performing membrane filtration on the centrate to obtain the filtrate;

[0072] (4) performing membrane concentration on the filtrate to obtain a concentrate; and

[0073] (5) The concentrate is freeze-dried and processed into Pu'er tea products.

[0074] The preparation method of the Pu'er tea product also includes (6) the step of molding the freeze-dried product to obtain a shaped Pu'er tea product.

[0075] The above steps (1)-(6) will be described in detail below, but these descriptions in no way limit the present invention.

[0076] In step (1), the tea raw material can be Pu-erh tea made by processing Yunnan big-leaf tea leaves, preferably Pu-er tea obtained by sun-drying and microbial fermentation of ...

example 1

[0105] Present example 1 provides a kind of preparation method of Pu'er tea, comprises the following steps:

[0106] Step A-1

[0107] The tea raw material is obtained by sun-drying and microbial fermentation of Yunnan large-leaf Pu-erh tea from Yunnan Province, and storing it through 3-year warehousing process.

[0108] Step A-2

[0109] According to the raw material / water ratio of 1:10, pour boiling water into the extraction tank, then put the tea leaves into the extraction tank according to the ratio, and extract twice, each extraction time not less than 30min.

[0110] Step A-3

[0111] The extracted tea soup is filtered through a 60-mesh filter and stored in a medium storage tank, and then the centrifuge (DHC-300) is turned on and centrifuged at a speed of 300L / h to remove dust, particles and macromolecular impurities. The tea soup after centrifugation has no impurities visible to the naked eye, and then it is stored in a medium storage tank.

[0112] Step A-4

[011...

example 2

[0126] The tea paste was prepared in the same manner as in Example 1, except that the ratio of raw materials / water was changed to 1:6.

Abstract

The invention provides a preparation method of a Pu'er tea product, a related Pu'er tea product and a device. The preparation method comprises the following steps: (1) extracting a tea raw material toobtain an extracting solution, (2) carrying out centrifugal separation on the extracting solution to obtain separated tea soup, (3) performing membrane filtration on the separated tea soup to obtainfiltrate, (4) carrying out membrane concentration on the filtrate to obtain a concentrate, and (5) freeze-drying the concentrate and processing it to obtain the Pu'er tea product. The invention provides the modern Pu'er tea product which is suitable for large-scale and large-batch production and can retain flavor substances and aroma substances in the processing process.

Description

technical field [0001] The invention belongs to the field of drinking products, and in particular relates to Pu'er tea products and a preparation method thereof. Background technique [0002] Tea, coffee, and cocoa are called the three major beverages in the world. At present, nearly 3 billion people in more than 160 countries and regions around the world have the habit of drinking tea. As one of the main producing countries of tea, China's development of tea industry and the export of Chinese tea culture it represents have greatly promoted the modernization of tea. With the continuous improvement of people's living standards in our country and the updating and upgrading of consumption concepts, the majority of people's tea drinking is not only to satisfy the thirst quenching needs in the general physiological sense, but to pay more attention to the needs of leisure, health care and appreciation. According to research reports, tea contains a variety of health-care ingredie...
