A kind of processing technology of Guangdong big-leaf yellow tea

Abstract

The invention belongs to the field of tea processing and particularly relates to a Guangdong big-leaf yellow tea processing technology which comprises the technical processes of fresh leaf picking and withering, fixation, spreading for cooling, rolling, heaping for yellowing, preliminary baking, spreading for cooling and drying. Compared with the traditional Guangdong big-leaf yellow tea processing technology, the Guangdong big-leaf yellow tea processing technology provided by the invention has the advantages that the processes of fixation, heaping for yellowing, and the like for tea are improved; and during fixation for tea, a low temperature-high temperature-low temperature fixation mode is adopted, so that the activity of most of enzymes in the tea can be destroyed, the green grass smell in the tea can be eliminated, favorable tea aroma can be produced, and a small amount of enzymes can be kept in the tea to achieve a fermentation effect in the operation of heaping for yellowing. The tea processed by the technology provided by the invention has the advantages of strip-shaped compact shape, heavy weight, yellow-green color, pure endogenous aroma, deep-yellow and bright liquor color, mellow and sweet taste, light-yellow leaf bases and complete leaf buds. The processed tea has unique color, aroma, taste and shape, the added values of the tea are improved, and the historical tea reputation of the Guangdong big-leaf yellow tea is kept and inherited.

Description

technical field [0001] The invention belongs to the field of tea processing, and in particular relates to a processing technology of Guangdong big-leaf yellow tea. Background technique [0002] Cantonese people love to drink tea, and Guangdong also produces good tea. There was once a poem "drinking tea in Guangdong, never to forget", which shows that Cantonese tea is not only loved by Cantonese people, but also leaves a deep impression on foreigners. Big-leaf green tea is a specialty of Guangdong, and its main production areas are located in Shaoguan, Zhaoqing, Zhanjiang and other counties and cities. It is one of the representative varieties of yellow big tea. [0003] Guangdong Dayeqing is processed from local Luokengyuan tea, Liannan Daye, Qinggui Daye and Hainan Daye tea tree varieties. The processing technology of traditional Guangdong big leaf green tea is the same as that of Yunnan sun-dried green tea. The initial production process is divided into five processes: wi...

AI Technical Summary

Problems solved by technology

[0004] In recent years, affected by the tea market orientation, the planting area of ​​large-leaf tea tree varieties traditionally used to manufacture yellow tea in Guangdong Province has been greatly reduced. Tea enterprises that process yellow tea are extremely rare, and the processing technology of yellow tea has not been well inherited. There are few relevant literatures. At present, tea leaves processed according to the processing procedures recorded in limited data often have problems such as uneven fermentation, over-fermentation, and bitter taste. It is difficult to process high-quality Guangdong big-leaf yellow tea.
