Problems solved by technology

[0005] The tangerine peel white tea currently on the market is simply softened tangerine peel and white tea and pressed together. This method is easy to make and cannot effectively integrate the aroma and taste of white tea and tangerine peel. Moreover, the ratio of the two is uneven, and the quality cannot be stabilized. , not only has a great impact on the taste and aroma, but also cannot bring out the health benefits of white tea and tangerine peel

Embodiment 1

[0034] A processing method for aging health-care old white tea, comprising ① picking, ② withering, ③ stacking, ④ drying, ⑤ storing, ⑥ mixing tangerine peel powder and ⑦ pressing and drying, wherein:

[0035] ②Withering: Spray the Luo Han Guo extract on the surface of the fresh leaves of tea leaves picked in ①, and then wither naturally in the room until the water content of the withered tea leaves reaches 20%. The Luo Han Guo extract is prepared as follows: The crushed Mangosteen is put into boiling water for 30 minutes, wherein 2.2kg of water is added for every 50g of Mangosteen,

[0036] The mass ratio of described Momordica grosvenori and the fresh leaf of tea is 2:5;

[0037] Cellulase aqueous solution, then stacked at 20-30°C with a thickness of 26cm for 44 hours, wherein the mass ratio of cellulase aqueous solution to tea leaves is 1:6;

[0038] ④Drying: Use graphite carbon baking cage to dry until the moisture content is 5%;

[0039] ⑤Storage: Store in a dry and cool ...

Embodiment 2

[0055] A processing method for aging health-care old white tea, comprising ① picking, ② withering, ③ stacking, ④ drying, ⑤ storing, ⑥ mixing tangerine peel powder and ⑦ pressing and drying, wherein:

[0056] ①When picking, the picked fresh leaves are one bud with two leaves, one bud with three leaves or one bud with four leaves, and the variety is Fuding Dabaicha or Fuding Dahaocha.

[0057] ②Withering: Spray the Luo Han Guo extract on the surface of the fresh leaves of tea leaves picked in ①, and then wither naturally in the room until the water content of the withered tea leaves reaches 25%. The Luo Han Guo extract is prepared as follows: Boil Luo Han Guo and put it into boiling water for 50 to get it, and add 2.5kg of water for every 50g of Luo Han Guo,

[0058] The mass ratio of described Momordica grosvenori extract to the fresh leaves of tea leaves is 2:6;

[0059] ③Stacking: First, evenly spray the cellulase aqueous solution with a concentration of 1.2% on the surface ...

Embodiment 3

[0073] A processing method for aging health-care old white tea, comprising ① picking, ② withering, ③ stacking, ④ drying, ⑤ storing, ⑥ mixing tangerine peel powder and ⑦ shaping and drying, wherein:

[0074] ② Withering: Spray the Luo Han Guo extract on the surface of the fresh leaves of ① picked tea leaves, and then naturally wither indoors for 52 hours until the water content of the withered tea leaves reaches 22%. The Luo Han Guo extract is prepared according to the following method : Put the smashed boiled Luo Han Guo into boiling water and boil for 30 minutes to obtain, wherein 2kg of water is added for every 50g of Luo Han Guo,

[0075] The mass ratio of described Momordica grosvenori extract to the fresh leaves of tea is 2:5.5;

[0076] 3. Stacking: Spray 1.5% cellulase aqueous solution on the tea leaves withered in step 2, and then stack them at 20-30°C for 42 hours, with a stacking thickness of 30 cm. The mass ratio of cellulase aqueous solution to tea leaves is 1:6.5...

Abstract

The invention relates to a processing method of aged health-care old white tea. The processing method comprises the steps of (1) performing picking; (2) performing withering; (3) performing piling; (4) performing drying; (5) performing storing; (6) mixing with dried orange peel powder; and (7) performing styling and drying. According to the method, the aged health-care old white tea is prepared bya white tea technology, the making method of the white tea is unique in technology, and the white tea does not need to be fried or kneaded, so that the permeability of cell membranes and enzymatic activity can be reserved to the maximum extent, leaf cells are subjected to a series of slow hydrolyzing and oxidation reaction under the situation that the leaf cells are not damaged or slightly damaged, and conjugated non-volatile precursor substances are converted into free volatile aroma components under the action of hydrolase, and foundation is established for unique color, fragrance and tastewhich are formed in the later stage.

Description

technical field [0001] The invention relates to the field of processing technology of white tea, in particular to an aged health-care old white tea and a processing method thereof. Background technique [0002] White tea is one of the special teas in China, mainly produced in Fuding City, Zhenghe County, Songxi County, Jianyang County and other places in Fujian Province. White tea belongs to slightly fermented tea, and its production method is unique, and the basic process is divided into withering and drying. Modern scientific research has initially revealed the health care mechanism of white tea: ①The flavonoid content in white tea is significantly higher than that of other teas. ② Among the six basic teas, white tea has the lowest free radical content. ③ The bactericidal effect of white tea is remarkable. ④White tea has good anti-oxidation, anti-aging, and anti-skin cancer effects. [0003] Tangerine peel is the dry and mature pericarp of Citrus reticulata Blanco and ...
