Embodiment 1

[0036] The manufacturing process of organic green tea, this process specifically comprises the following steps:

[0037] (1) Picking: pick fresh organic green tea leaves with one bud and one leaf or one bud and two leaves, put the picked tea leaves in a clean and breathable bamboo basket or bamboo grate, and put them in a cool and ventilated place for later use;

[0038] (2) Cleaning: Rinse the picked tea leaves twice with spiral water flow, put them in a bamboo grate to drain, and let the natural wind blow to the surface of the tea leaves without obvious water droplets; when washing, the amount of tea leaves and water is calculated as 1:12 in mass ratio ;

[0039] (3) Spreading: After the above-mentioned rinsed tea leaves are loosened, they are spread on a shelf in a cool and ventilated room. The thickness of the spread is 1.5cm, the room temperature is controlled at 15°C, and the humidity is controlled at 40%. Turn it over once, spread it for 4.0 hours, and the water conten...

Abstract

The invention belongs to the field of green tea, and particularly discloses a preparation technology of organic green tea. The technology comprises the following steps of picking, cleaning, spreading, deactivating enzyme by phases, rolling, aging, extracting fragrance, finely selecting, and packaging. The technology has the advantages that by shortening the spreading time, the bitter taste of the finished tea is effectively reduced; by deactivating enzyme by phases for multiple times, rolling at different pressure and aging, the contents of tea polyphenol and catechinic acid in the prepared green tea are effectively increased; after detecting, compared with the green tea prepared by the traditional technology, the content of tea polyphenol in the green tea prepared by the technology is improved by about 7 to 10%, and the content of catechinic acid is improved by about 4 to 6%; the fragrance of prepared green tea is heavy and lasting, the color is yellow and green, the quality is high, and the appearance and color of tea leaves are excellent.
