Abstract

The invention discloses a processing method of rosa-roxburghii leaf tea and belongs to the technical field of tea processing. The processing method comprises the following steps: firstly picking fresh rosa-roxburghii leaves, withering the leaves, feeding into a fixation machine for fixation, then rolling the rosa-roxburghii leaves after fixatioin, then carrying out secondary fixation, then carrying out rolling, and finally shaping and drying to obtain the rosa-roxburghii leaf tea. The processing method disclosed by the invention has the advantages that the rosa-roxburghii leaf tea is processed by utilizing the rosa-roxburghii leaves on branches trimmed from a rosa-roxburghii tree, and wastes are changed into valuables, so that the processing cost of the rosa-roxburghii leaf tea is low; and after the processing method is adopted for treating the rosa-roxburghii leaves, the beneficial components in the rosa-roxburghii leaves are effectively retained, and the mouth feel is improved; and the processed rosa-roxburghii leaves are mellow in taste, are tasty and refreshing, are compact, round-straight and neat and have large appreciating and artistic values.
