Problems solved by technology

Although my country has formulated and promulgated tea tree pesticide restrictions, permitted and recommended types and methods of use, environmental pollution and pesticide residues cannot be fundamentally eliminated, which has become one of the obstacles to green tea production.
According to the existing green tea production process, the residual pesticides and harmful substances deposited on the leaves will remain in the finished tea without effective treatment

Abstract

The invention discloses a preparation method of jujube bud-leaf green tea, which comprises the following steps: (1) Blanching green tea: according to the weight of water and bud-leaf 6-10: 1, immerse fresh and tender jujube buds or leaves in boiling water, heat until boiling and remove , Immediately immerse in clean water at room temperature and stir to cool; ⑵Dehydration: After the water on the surface of the cooled buds and leaves is removed by centrifugation, the moisture content of the buds and leaves is reduced to 40%-45% by blast drying; 3. Frying and rolling: the dehydrated buds Put the leaves into the tea pot and stir-fry repeatedly and fully knead; (4) drying: dry the fried and kneaded buds and leaves, so that the moisture content of the cooled buds and leaves drops to 7.0% to 7.5%, and then screen and discard the broken pieces to obtain jujube buds and leaves. green tea. The invention adopts the blanching method to kill greens, which can wash away harmful components in the sediments on the surface of buds and leaves, reduce or eliminate pesticide residues, keep the active ingredients of jujube buds and leaves as much as possible, and fully embody the green and clear tea soup, tea Round and bright green tea characteristics.

Description

technical field [0001] The invention relates to a method for preparing tea, in particular to a method for preparing jujube bud-leaf green tea. Background technique [0002] Asia is the main producer of tea in the world, and the tea production of China, India, Sri Lanka, Kenya and Indonesia accounts for 80% of the world's total production. In 2001, China’s tea gardens covered an area of ​​11,400 hectares, produced 701,700 tons of tea, exported 249,600 tons, and an export value of US$342 million; in 2010, the area of ​​tea gardens was 19,700 hectares, produced 1.475 million tons of tea, exported 302,500 tons, and exported 784 million US dollars . In 2012, the area of ​​tea gardens was 21,000 hectares, and the tea production was 1.915 million tons, ranking first in the world; the export was 320,000 tons, ranking second after Kenya. China is the hometown of tea, but it is not a big tea drinking country. The average annual tea consumption of Chinese people is about 400 grams, ...
