Problems solved by technology

[0004] Fixing is an essential process in the processing of fresh leaves. Through fixing, the tea can undergo a series of chemical reactions and endow the tea with different qualities. The existing fixing is mainly to destroy the enzyme activity in the tea through high temperature. Steam fixing is to use steam Tea is treated at high temperature. The existing steam fixation is mainly carried out through the evaporation of water vapor. The effect of this fixation method is not satisfactory. actively seeking

Abstract

The invention relates to a steam liquid for steaming de-enzyming of guapian and a processing technology. The steam liquid comprises the following raw materials by weight: 0.2-0.4 part of glutathione peroxidase, 2-3 parts of salt, 3-5 parts of thiamine, 0.4-0.8 part of distamycin A, 0.8-1.2 parts of sodium phosphate, 0.5-1.0 part of superoxide dismutase, 0.3-0.8 part of sodium citrate, 2-4 parts of potassium borate, and 40-50 parts of water. The steam liquid provided by the invention is used for steaming de-enzyming, and then processing is carried out, the obtained tea has few enzyme-catalyzed reaction, constant tea polyphenol content, small loss of beneficial ingredients and high quality, and also the shelf life of the tea can be prolonged.

Description

Technical field [0001] The invention relates to the technical field of tea processing, in particular to a steam liquid for steam curing of melon slices and a processing technology. Background technique [0002] Luan Guapian, a traditional Chinese historical famous tea, one of the top ten famous teas in China, referred to as Guapian, Piancha, is produced in the area of ​​Dabie Mountain, Lu'an City, Anhui Province.
