Preparation method of herba centellae substitutional tea

Abstract

The invention discloses a preparation method of herba centellae substitutional tea. The preparation method comprises the steps of (1) collecting: collecting centella leaves in two seasons of summer and autumn; (2) cleaning and selecting: removing foreign matters, branches or yellow leaves; (3) spreading for cooling: ventilating and spreading for cooling the centella at 26 to 30 DEG C; (4) de-enzyme: performing de-enzyme treatment on the centella leaves; (5) molding: putting raw materials after de-enzyme on rolling equipment, spreading for cooling firstly, then rolling to obtain strip decoction pieces; (6) drying: drying the rolled leaves under the condition that the temperature is 50 to 110 DEG C and the thickness is 1.0 to 3.0 cm, and the drying time is 1 to 2h; (7) controlling the humidity of the dried herba centellae substitutional tea to below 60 percent, and cooling the dried herba centellae substitutional tea to room temperature, and then performing subpackage to obtain a finished product. According to the preparation method of the herba centellae substitutional tea, all aspects such as the purity of materials, sensation of sense organs of the color, shape, smell and the like of the tea, the mobility of yield production, moisture and ash content, the content of active ingredients, long-term stability, brewing property of the decoction pieces, and the like are obviously superior to that of the existing technical scheme.

Description

Problems solved by technology

The process of the present invention solves the problem that needs to be solved in making a single Centella asiatica substitute tea by selecting more reasonable parts for making tea, inactivating enzymes in leaves, rolling and molding, sterilizing and drying: the commonly used parts of Centella asiatica have many impurities , The active ingredient degrades quickly, the storage time is short, the active ingredient dissolves slowly, the dissolution is small, and there is no good leaf shape, taste and smell after re-foaming.
