Black and green scented tea processing technique

Abstract

The invention discloses a black and green scented tea processing technique. The processes of fresh leaf preparation, spreading, de-enzyme, rolling and drying for producing green tea and the processes of fresh leaf preparation, deterioration, rolling, fermentation and drying for producing black tea are combined, the same batch of fresh tea leaves are divided into two parts to be processed separately and combined again in the rolling process so as to obtain the same appearance, and flower juice is added in the fermentation process so that the tea has the scent of flower. The processing technique is based on the chemical reaction relation between tea polyphenol, polyphenol oxidase and oxygen. High-temperature de-enzyme inactivates polyphenol oxidase, and green tea does not become red after the rolling process; the activity of polyphenol oxidase is maintained during rolling of black tea, and tea polyphenol becomes black tea characteristic substances including theaflavin and thearubigins through catalytic oxidation after making contact with oxygen. During combined rolling on the same machine, raw materials of the same level have relatively uniform strip forming rate, strip tightness and cell disruption degree, and then finished tea has uniform appearance and good color.

Description

technical field [0001] The invention relates to the field of tea-making technology, and more specifically relates to a processing technology of red-green flower-scented tea. Background technique [0002] In the science of tea making, there are eight major processes in the processing of tea leaves, including withering, greening, greening, veneering, rolling, fermentation, heaping, and drying. The formation of different types of tea, among which, green tea and black tea are the most obvious. The difference between the two is reflected in the process of "killing first and then kneading" and "kneading first and then killing". According to the theory of traditional Chinese medicine, green tea is cool in nature and black tea is warm in nature. Therefore, some tea drinkers drink the two together. It is used in tea product development. [0003] Computer users who sit in the office for a long time and have a cold physique are most suitable for mixed red and green tea, but the taste...
