Embodiment 1

[0010] The present embodiment provides a kind of processing technology of Rosa roxburghii black tea, and concrete processing method is as follows:

[0011] Put the picked fresh Rosa roxburghii young leaves on the dustpan in the processing room to wither, the room temperature is 23°C, the relative humidity is 65%, the tile thickness is less than 2cm, the withering time is 10 hours, and the moisture content of the leaves to be withered reaches 60%-64%. The leaf shape is shrunken, the leaf quality is soft, the tender stem is soft and bends continuously, the leaves are soft when pinched by hand, and form a ball tightly, and can slowly disperse after letting go, the gloss of the leaf surface disappears, the leaf color is slightly dark green, and the green grass changes It is weak and emits a certain aroma, which is a sign of moderate withering. Put the withered young leaves of Rosa roxburghii into a kneading machine and knead until the cell damage rate reaches more than 85%, and mor...

Abstract

The invention provides a processing technology of leaves of roxburgh rose black tea, and belongs to the technical field of improvement of tea leaves. The processing technology comprises the followingsteps: putting the picked fresh tender leaves of roxburgh rose on a dustpan for withering in a processing room, wherein the room temperature is 23 DEG C, the relative humidity is 65%, the tile thickness is less than 2cm, and the withering time is 8-12 hours; when the moisture content of the withered leaves reaches 60%-64%, rolling the withered tender leaves of roxburgh rose in a rolling machine; when the broken cell rate reaches 80% or more, 90% or more of the leaves become strips after the rolling, the juice overflows, and the leaves feel wet and sticky to a hand and can be held into a ball while having moderate looseness after being released, putting the rolled tender leaves of roxburgh rose into a fermentation tank, wherein the temperature is 23 DEG C, the humidity is 89%-93%, and the fermentation time is 4 hours; drying in a dryer; after the drying is finished, spreading and cooling to room temperature, and then packaging and storing. The processing technology aims to solve the problem that most of the pruned leaves of roxburgh rose are directly discarded at present and consequently resource waste is caused since the leaves of roxburgh rose have relatively high nutritional value.

Description

technical field [0001] The invention provides a method for processing roxburghii branches and leaves, which belongs to the field of roxburghii leaf processing. Background technique [0002] Rosa roxburghii is a unique emerging fruit tree in my country, and there are many wild species of Rosa roxburghii in Guizhou. Rosa roxburghii is rich in trace elements, amino acids and various active substances, which makes Rosa roxburghii have pharmacological functions such as detoxification, sedation, and anti-oxidation. The medicinal properties of Rosa roxburghii are also recorded. Rosa roxburghii flower is flat in nature, sweet in taste, effective in stopping dysentery and diarrhea, and has medicinal value, and the essential oil of Rosa roxburghii contains higher hydrocarbons, aldehydes, alcohols, phenols, alkenes, and organic acids, which can be widely used in health care products, nutritional products, pharmaceutical products, cosmetics. Rosa roxburghii can be directly processed in...
