Abstract

The invention relates to the technical field of making of black tea beverages, in particular to a method for making a rosemary black tea beverage. The method solves the problem that the conventional technology for making the black tea beverage is not suitable for producing the rosemary black tea beverage. The method comprises the following steps of: adding water into rosemary leaves, and performing microwave water extraction, filtration and ethanol extraction to obtain an extract; putting the extract and the filtrate into a reaction tank or a fermentation tank, adding rosemary leaf paste formed by grinding fresh leaves, introducing air or oxygen, heating, stirring, fermenting, filtering leaf residue, obtaining rosemary black tea soup by high-speed separation and membrane filtration, and making the rosemary black tea beverage, rosemary black tea concentrate and instant rosemary black tea powder by using the black tea soup according to the required concentration proportion. The method for making the rosemary black tea beverage has the advantages of wide raw material source and stable and excellent quality of the product, reduces the production cost, improves the economic benefits, and is favorable for industrial automatic control and market promotion.

Description

Technical field [0001] The invention relates to the technical field of making black tea beverages, in particular to a method for making rosemary black tea beverages. Background technique [0002] Rosemary black tea belongs to fermented tea, with reddish brown color, oily, rich fragrance, sweet, mellow taste, ruddy soup, and excellent health care functions. At present, the existing production methods of black tea beverages mainly extract black tea juice directly from black tea, and obtain black tea beverages through filtration, concentration, drying, blending, sterilization, and filling. However, the production process of rosemary black tea is complicated and the selection of materials is exquisite. If the rosemary black tea is used as raw material to process beverages, the processing cost is high, the production cycle is long, the processing technology is cumbersome, the quality is unstable, and the equipment and capital investment are large, which seriously hinders The ...
