Embodiment 1

[0023] A processing technology for long-leaf pekoe white tea, comprising the steps of:

[0024] (1) Picking: pick jade-white fresh leaves with one bud and one leaf, which are long-leafed pekoe. The buds and leaves form flowers, uniform in size, and short stalks;

[0025] (2) Withering: After removing stems, slices, wax leaves, red leaves, and dark leaves, wither in sunlight until the moisture content of the tea leaves reaches 50%, and the withering time is 14 hours;

[0026] (3) Degreening: Put the withered white tea into the dryer until the moisture content is 20%, then spread the tea leaves for micro-fermentation, and the fermentation time is 12 hours;

[0027] (4) Drying: Initial drying, the temperature of the dryer is 100°C, the drying time is 10 minutes, the cooling time is 20 minutes, and the second drying is at 70°C, the drying time is 15 minutes, when the moisture content of the tea leaves is lower than 5% Take it out and put it in the freezer for 3 hours, take it out...

Embodiment 2

[0031] A processing technology for long-leaf pekoe white tea, comprising the steps of:

[0032] (1) Picking: pick jade-white fresh leaves with one bud and one leaf, which are long-leafed pekoe. The buds and leaves form flowers, uniform in size, and short stalks;

[0033] (2) Withering: After removing stems, slices, wax leaves, red leaves, and dark leaves, wither in sunlight until the moisture content of the tea leaves reaches 60%, and the withering time is 16 hours;

[0034] (3) Degreening: Put the withered white tea into the dryer until the moisture content is 30%, then spread the tea leaves for micro-fermentation, and the fermentation time is 14 hours;

[0035] (4) Drying: Initial drying, the temperature of the dryer is 120°C, the drying time is 15 minutes, the cooling time is 20 minutes, and the second drying is at 80°C, the drying time is 20 minutes, when the moisture content of the tea leaves is lower than 5% Take it out and put it in the freezer for 3 hours, take it out...

Abstract

The invention belongs to the technical field of tea processing and relates to a long leaf pekoe white tea processing technology. The technology comprises (1) picking: picking white jade-color fresh leaves of long leaf pekoe with one leaf and one bud, (2) withering: removing stems, slices, wax leaves, red leaves and dark leaves and then carrying out withering under sunlight, (3) de-enzyming: putting the withered white tea into a dryer until the moisture content is 20 to 30%, then spreading the tea and carrying out micro-fermentation for 12 to 14 hours, (4) drying: carrying out primary baking through a baking machine at a baking machine temperature of 100 to 120 DEG C, carrying out spreading cooling for 20 minutes and carrying out re-baking at a temperature of 70 to 80 DEG C, and (5) packaging. The technology can effectively prevent the loss of nutrients of the white tea and keeps complete appearance of the white tea. The cultured long leaf pekoe white tea has fluff covering the whole white tea leaf and can produce the tea soup with a fresh fragrance and a mellow taste. The technology has simple processes, is easy to produce in a large scale, removes the bitter taste and realizes a mellow tea fragrance.

Description

technical field [0001] The invention relates to a long-leaf pekoe tea processing technology, which belongs to the technical field of tea processing. Background technique [0002] Long-leaf Pekoe was bred by the Tea Research Institute of the Yunnan Academy of Agricultural Sciences from 1973 to 1985 from the Nannuo Mountain tea tree population in Menghai County using the single-plant breeding method. It is cultivated in large areas in Xishuangbanna, Simao, Lincang and other places in Yunnan. In 1985, Yunnan Crop Variety Approval Committee identified it as a provincial variety. [0003] Long-leaf Pekoe has obvious trunk, large tree vigor, and unfolded tree posture. It is an arbor type and has strong cold resistance, drought resistance and disease resistance. The buds are dense, the buds and leaves are yellow-green, and there are many hairs. Long-leaf pekoe tea is of high quality, and green tea is beautiful in appearance and good in quality. Made of black tea, the appearance...
