Abstract

The invention discloses a preparation method of cold water-brewed type tea leaves. The preparation method comprises the following steps: (1) spreading the harvested tea leaves, spraying modification liquid to the surfaces of the tea leaves, and spreading for 3-4 days; (2) putting the spread tea leaves on a CTC production line, performing primary cutting with a Rotorvane rotor machine, cutting up the withered leaves with a CTC three-head weft machine, and rolling into particles; spraying fermentation broth to the tea leaf particles; mixing uniformly and fermenting on a ventilation continuous fermentation bed, wherein the fermentation treatment time is 40-50 min; finally, drying to obtain a finished product. The preparation method of cold water-brewed type tea leaves disclosed by the invention is environmentally friendly, and can realize large-scale batch production and has high efficiency; the dissolution quantity of the contents in the prepared cold water-brewed type tea leaves is large, and the brewing effect is remarkable.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and in particular relates to a preparation method of cold water brewing tea. Background technique [0002] Tea leaves processed by traditional techniques can only be brewed with hot water. If brewed with cold water, it is difficult to extract the active ingredients of the tea leaves, and the aroma and taste are very poor. However, consumers in Europe, America and other countries prefer cold drinks, and almost 90% of tea leaves are used to make iced tea for drinking. Therefore, in order to make iced tea, water must be boiled to brew tea leaves, and then wait for the tea soup to cool down, which often takes more than 1 hour. For this reason, British Unilever company has developed a kind of processing technology of new cold water brewing type tea, and obtained European patent and world patent in September 2001. Through special processing, the tea can be leached in 15°C water within 5 minute...
