Abstract

The invention discloses a processing method of tea flowers, relating to the technical field of processing. The processing method comprises the following steps: harvesting tea flower buds from the middle ten days of October to the first ten days of December; wiping out receptacles, spreading on a water sieve; freezing the buds in a gauze bag at a temperature of being less than 20 DEG C, freezing for 12-14h; freeze-drying the buds in a vacuum dryer, vacuumizing when the temperature is lower than -20 DEG C, starting an oil heating system when the pressure is vacuumized to -0.1 Mpa, continuously drying for 24-26h by heating until the content of water in the buds is not greater than 4 percent; and baking the buds in a baking machine at a temperature of 90-100 DEG C for 15-20min. According to the processing method, the problem that the quality is not favorably improved because the plumpness is poor, the appearance is unattractive, the color is not fresh and alive, the fragrance is not pure, the color is slightly yellow and not bright, and the like is solved.

Description

technical field [0001] The invention relates to the technical field of tea product processing, in particular to a method for processing tea tree flowers.

Based on the above reasons, tea farmers adopt Strengthen the management of fertilization, thereby inhibiting the blooming of flower buds, or remove flower buds by manual removal, pruning, etc., to ensure the vegetative growth of tea leaves. At present, it has been found th...
