Embodiment 1

[0023] In the new 20-acre standard factory area of ​​Guizhou Meitan County Xuelanxiang Tea Industry Co., Ltd. located in the tea product processing industrial park of Xinglong Town, Meitan County, Guizhou Province, the black tea processing of Eagle tea is carried out. The site selection, infrastructure layout, environmental conditions and sanitation conditions are all in line with the relevant technical specifications of DB52 / T 630 "Basic Conditions for Tea Processing Sites in Guizhou".

[0024] The raw materials of fresh leaves are collected from the green food production base built by the 6-year-old clone of Youshu, which is the raw material plant of two kinds of eagle tea, Leopard skin camphor and Red fruit yellow meat Nan in Tiewa Village, Huangjiaba Town, Meitan County; / T391 "Environmental Quality of Green Food Production Areas" related regulations; because the raw material plants of eagle tea do not like fertilizer, they have the characteristics of biology and ecology su...

Embodiment 2

[0035] Processing location and raw material are with embodiment 1.

[0036] ) Caiqing: Before 11 am on November 20, 2017, use branch shears to trim the crown of the tree. Excess autumn shoots and other weak branches should be trimmed and trimmed in autumn; the branches and leaves will be transported back to the planting base in a ventilated and cool place in a bamboo basket, and 50kg of fully developed and mature leaves of the year will be picked by hand, and the damaged leaves, scorched edges, and pests will be removed. Spotted leaves.

[0037] 2) Spreading and airing: at 14:00 in the afternoon, the fresh leaves are transported to the processing factory and spread out; spread out in a clean and hygienic bamboo plaque; the thickness of the spread leaves is 8cm, and spread out until 7:00 am on November 21, a total of 17 hours. The leaves become soft, gray-green in color, slightly camphor woody, and the water content of the leaves is 50%.

[0038] ) Finishing: steam killing, 2...

Abstract

The invention relates to a processing method of Laoying dark tea. The method comprises the following technical links: (1) picking green leaves; (2) performing spreading for cooling; (3) performing fixation; (4) performing rolling; (5) performing pile fermentation; (6) performing shaping and primary baking; (7) performing final firing; and (8) performing sieving and performing packing. In order tosufficiently develop and utilize the efficacy of reducing blood sugar and reducing blood lipid of flavonoid, polyphenols, polysaccharide and the like in raw material plants for the Laoying tea and improve the health-care efficacy of minerals of calcium, iron, zinc, selenium, magnesium and the like beneficial to metabolism of human bodies, and based on research of a processing technology primarilymeeting the hygienic index of NY / T288 green food tea and taking account of distinctive physical and chemical indexes and organoleptic quality of tea products, the invention optimally establishes the dark tea technology suitable for large-scale processing of ripe leaves of two kinds of raw material plants, litsea coreana and actinodaphne nees, for the Laoying tea, and provides reliable technical support for green processing and utilizing of high-flavone high-calcium tea products of the Laoying dark tea.
