Embodiment 1

[0028] Example 1: A method for preparing high γ-aminobutyric acid tea, the preparation steps are as follows:

[0029] A. Withering: Put the picked fresh plum leaves in a thin indoor stall at a temperature of 20-24°C and a relative humidity of 60-65% for 10-12 hours to obtain withered plum leaves with a water content of 60-64%.

[0030] The high-gamma-aminobutyric acid tea of ​​this embodiment uses needle-shaped plum fresh leaves as raw materials. The growth environment of the raw materials requires a large temperature difference between day and night. The highest temperature during the day can reach 28-35°C and the lowest temperature at night can reach 2-6°C. A large amount of γ-aminobutyric acid is accumulated in the leaves of plum tea grown under a kind of adversity environment, which increases the content of γ-aminobutyric acid in fresh leaves of plum tea. This high-gamma-aminobutyric acid plum can be planted in spring and autumn greenhouses or areas with large temperature diffe...

Embodiment 2

[0052] Example 2: A method for preparing high-gamma-aminobutyric acid tea, the preparation steps are as follows:

[0053] A. Withering: Put the picked fresh plum leaves in a thin indoor stall at a temperature of 20-24°C and a relative humidity of 60-65% for 10-12 hours to obtain withered plum leaves with a water content of 60-64%.

[0054] B. Desalination: Put the withered European plum leaves into a destructuring machine at a temperature of 180-200°C for 45-50 seconds, and obtain plum leaves with a moisture content of 55-58%.

[0055] The curing machine in this embodiment adopts the 6CAT-30 drum type famous tea curing machine, which starts to throw leaves when the equipment temperature reaches 180-200°C and the air temperature at the exit reaches 90°C. The amount of leaves throwing is about 30 kg per hour. The leaves should be thrown uniformly. Generally, the processing time of the leaves in the drum is 45-50 seconds; the moisture content of the leaves of the European plum is 55-58%...

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 method for preparing high-gamma-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. The protein, amino acids, fats, carbohydrates and various vitamins and minerals contained therein are all essential nutrients for the human body. But the caffeine in tea currently sold on the market can excite the central nervous system, so drinking tea at night often affects sleep. [0003] Prunus edulis is a unique shrub species of the Rosaceae cherry genus in my country. Its crown ratio is large, the plant is short, and it grows fast. It can effectively prevent soil erosion and play an important role in ecological management. Each kilogram of plum leaf contains 17,300 mg of calcium, so plum leaf is also call...
