Embodiment 1

[0028] Embodiment 1: a kind of preparation method of high γ-aminobutyric acid tea, its preparation steps are as follows:

[0029] A, withering: the fresh leaves of Prunus punctatus picked are placed in the air for 10-12 hours in a room with a temperature of 20-24° C. and a relative humidity of 60-65%, to obtain withered leaves of Prunus auricula with a water content of 60-64%.

[0030] The high γ-aminobutyric acid tea in this example uses the fresh leaves of Prunus punctatus as raw material. The growth environment of this raw material requires a large temperature difference between day and night. Plum leaves grown in this adversity environment accumulated a large amount of γ-aminobutyric acid, which increased the content of γ-aminobutyric acid in the fresh leaves of Prunus japonica. This kind of high GABA can be planted in greenhouses in spring and autumn or in areas with large temperature difference between day and night. Picking of fresh leaves of Plum leaves is done manual...

Embodiment 2

[0052] Embodiment 2: a kind of preparation method of high γ-aminobutyric acid tea, its preparation steps are as follows:

[0053] A, withering: the fresh leaves of Prunus punctatus picked are placed in the air for 10-12 hours in a room with a temperature of 20-24° C. and a relative humidity of 60-65%, to obtain withered leaves of Prunus auricula with a water content of 60-64%.

[0054] B. Fixing: putting the withered leaves of Prunus aurantium into a fixing machine with a temperature of 180-200° C. for 45-50 seconds to obtain the de-greening leaves of Prunus aurantium with a moisture content of 55-58%.

[0055] The de-greening machine of this embodiment adopts the 6CAT-30 type cylinder-type famous tea de-greening machine. When the temperature of the equipment reaches 180-200 ° C and the air temperature at the leaf outlet reaches 90 ° C, the leaves are thrown, and the amount of leaves thrown is about 30 kilograms per hour. The leaves should be thrown evenly. Generally, the proc...

Abstract

The invention relates to a preparation method of high gamma-aminobutyric acid tea. The preparation method comprises the following steps: withering fresh Cerasus humilis leaves, de-enzyming, twisting, carrying out primary baking, carding, drying, screening and carrying out other steps to obtain the high gamma-aminobutyric acid tea. The high gamma-aminobutyric acid tea can lower the blood pressure,improve sleeping, strengthen memory, recompose the nerve and resist anxiety, has the function of preventing and treating epilepsy, and can postpone cerebrum senility and regulate the male reproductive function. The high gamma-aminobutyric acid tea contains high free valine, isoleucine, leucine and various other human necessary branched-chain amino acids, and can provide energy reserve for long-time endurance exercises and promote the recovery of sports fatigue. The high gamma-aminobutyric acid tea contains more asparagine, and can form biochemical hindrance for cancerated cells in vivo, thereby inhibiting the growth and reproduction of cancer cells and having synergistic and attenuating effects on chemotherapy of malignant tumors.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a preparation method of high γ-aminobutyric acid tea. Background technique [0002] my country's tea culture has a long history, and tea has become a necessity in people's daily life. Tea contains more than 300 kinds of nutrients that are beneficial to the human body, and the protein, amino acid, fat, carbohydrate and various vitamins and minerals contained in it are all necessary nutrients for the human body. However, the caffeine in tea sold on the market can excite the central nervous system, so drinking tea at night often affects sleep. [0003] Prunus is a kind of Rosaceae cherry shrub species unique to my country. It has a large crown ratio, short plants, and fast growth. It can effectively prevent soil erosion and play an important role in ecological governance. There are 17,300 mg of calcium per kilogram of Plum leaves, so Plum leaves are also called calcium frui...
