Abstract

The invention relates to a processing method of green tea. The processing method comprises the processing steps of raw material selection, picking, spreading, fixation, spreading, rolling, shaping, baking and the like, wherein the types of selected raw materials are strictly controlled to be Nanjiang #1, Zaobaijian #5 or Fuding Dabai tea; the raw materials are required to be picked in a harmless ecological tea garden at the elevation of 550-650m in sunny days in the middle of March under the temperature of 20-25 DEG C. The processing method is executed by the processing technologies such as high-quality raw material selection and optimized spreading, so that the quality of the green tea is improved.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a green tea processing method. Background technique [0002] Green tea is a non-fermented tea, which is made from tea tree buds and leaves through three typical processes of killing greens, rolling, and drying. It is named green tea because of its quality characteristic of green leafy soup. [0003] The quality characteristics of green tea require that all flavanols are not oxidized or change less, so the process uses high temperature and high heat to destroy the enzymatic oxidation and prevent the oxidation of catalyzed flavanols. At the same time, the heating process of fresh leaves, high temperature conditions and corresponding water changes in the enzymatic heat denaturation treatment all promoted a series of non-enzymatic chemical reactions in its contents. Therefore, the quality appearance of "green leaves and green soup" and the chemical composition characteristic...
