Abstract

The invention discloses a processing method of dendrobium candidum flower tea. The processing method comprises the steps of performing picking, performing choosing, performing spreading for cooling, performing screening, performing fixation, performing resurgence, performing final-panning, performing drying and the like. According to the processing method of the dendrobium candidum flower tea provided by the invention, manners of high-temperature fixation and low-temperature drying are adopted, besides, the step of performing resurgence is additonally set after the fixation, so that by the processing method, effective components in the flower tea can be sufficiently reserved, the quality characteristics of the shape, the fragrance and the like of the flower tea can be improved, and the quality guarantee period of the flower tea can be prolonged. In addition, the method is low in cost, high in efficiency and suitable for mass production.

Description

Technical field [0001] The invention relates to the technical field of scented tea processing, in particular to a processing method of Dendrobium officinale flower tea. Background technique [0002] Dendrobium officinale belongs to the orchid family, and its flowers are yellow-green. Modern medical research has confirmed that the medicinal ingredients of Dendrobium candidum mainly include polysaccharides, dendrobine, amino acids and other substances that can improve human immunity, enhance memory, and resist aging. [0003] Because Dendrobium officinale is a seasonal flower, it is very difficult to obtain flowers outside the flowering season. China has a tradition of frying scented tea since ancient times. At present, the production methods of Dendrobium candidum flower tea include traditional frying method, vacuum drying method, microwave drying method and freeze drying method. Due to the high production cost of vacuum drying method, microwave drying method and freeze drying meth...
