Abstract

The invention relates to the technical field of processing mugwort tea, in particular to a processing method of mugwort tea, which is made by natural drying, natural withering, steam treatment, pulverization, extraction, electric field treatment, concentration and spray drying of mugwort leaves. The mugwort leaf tea prepared by the invention has good sensory quality and storage effect, and has the characteristics of high dissolution rate of nutrients, good clarity, harmonious smell, and good taste. The method of the invention can make it contain volatile oil, and the oil is mainly eucalyptus oil α-thujone, α-phellandrene, β-eugenene, camphene, camphor, fennelone, trans-reedol, and terpineol are dissolved and effectively retained in large quantities. Therefore, mugwort tea has anti-inflammatory properties , cough, expectorant health effects.

Description

technical field [0001] The invention relates to the technical field of processing mugwort tea, in particular to a processing method of mugwort tea. Background technique [0002] Artemisia argyi belongs to the spleen, liver, and kidney meridians. It is warm in nature and bitter in taste. The whole herb is used as medicine. special, thus limiting its scope of application. [0003] Using wormwood leaves for tea can improve the medicinal and edible value of tea. For example, Patent No. 201210313359.5 discloses a method for making wormwood leaf tea, which includes the following steps: picking, picking wormwood leaves; steaming, making the plucked wormwood leaves Put it into the preheated steaming drum, the preheating temperature range is 90-100°C, the steaming drum rotates at a speed of 30 revolutions per minute, the steaming time is 60 seconds, and then cool immediately; knead, The steamed mugwort leaves are put into a kneading machine for kneading, hot air treatment at a temp...
