Abstract

The invention discloses a black tea processing technology. The black tea processing technology comprises the steps of pretreatment, fresh leaf selection, leaf spreading, leaf cooling, rocking of green leaves, rolling, fermenting, incipient drying, drying, fragrance increasing and packing. The tea processed through the technology is good in quality, the content of amino acids is increased, the content of tea polyphenols and caffeine is reduced, and the black tea is free of the bitter taste.

Description

technical field [0001] The invention relates to a processing technology of black tea, in particular to a processing technology of black tea with good tea quality. Background technique [0002] Black tea is a fully fermented tea, which is made from the young buds and leaves of tea trees through withering, rolling (or kneading and cutting), fermentation, and drying. The common feature is "red soup and red leaves". The more representative black teas in my country include: Keemun black tea known as the "hero among teas", Yunnan black tea known as the "star of teas", and Yingde black tea known as the "rising star". Black tea is different from black tea in nutritional and health ingredients due to fermentation. It has the characteristics of mildness, health, stomach, and beauty. It is suitable for drinking by most people and is welcomed by many middle-aged and elderly people. It is a major tea with the largest number of drinkers and the most special drinking form in the world. ...
