Abstract

The invention belongs to a production process of a tea beverage, in particular a production process of a fermented tea beverage, and aims to solve the problems that the prepared tea beverage prepared by the existing process contains tea residue solids and the liquid is turbid after being filled. Red tea is placed in a stainless steel cylinder to be subjected to water immersion cleaning and dust cleaning with normal temperature pure water to keep that the red tea contains certain moisture; the clean tea which is subjected to water immersion cleaning is decocted; the decoction utensil is a stainless steel jacketed kettle; the steam decoction temperature is 95 DEG C, and the decoction time is 10 minutes; the tea is filtered and clarified after being decocted, namely the tea is secondarily filtered by using a diatomite filter and a micro-porous membrane filter (200 meshes) respectively and clarified; after tea liquor is obtained, yeast, lactic acid bacteria and acetic acid bacteria strains are added to be subjected to mixed fermentation for 48 hours; anthocyanin powder is mixed to obtain the fermented tea beverage. The fermented tea beverage prepared by using the process does not contain the tea residue solid, the liquid is clear and transparent after being filled, and the color is light brownish.

Description

technical field [0001] The invention belongs to a production process of tea beverage, in particular to a production process of fermented tea beverage. Background technique [0002] The production process of the previous fermented tea beverages is: generally, black tea leaves are extracted by high-temperature soaking (90°C), low-temperature soaking (50°C) and ultrasonic soaking (50°C) to extract tea juice, and auxiliary raw materials anthocyanins and carbonic acid are added. synthesis. The production process of the existing fermented tea beverage is complex, and the fermented tea beverage made by this process contains solid tea leaves, and the liquid is cloudy after filling. Contents of the invention [0003] The object of the present invention is to provide a production process of a fermented tea beverage that does not contain tea dregs and has a clear and transparent liquid after filling. [0004] The technical scheme that realizes the object of the present invention: ...
