Abstract

The invention discloses a processing method of Longjing tea containing herba dendrobii. The processing method comprises the following steps: fresh leaf picking, spreading for airing, rocking, blanching, fixation, rolling, scenting and drying. The processing method of the Longjing tea containing herba dendrobii has the following beneficial effects: the taste of Longjing tea is enriched, the cells of the tea leaves are injured and damaged by rocking, so tea polyphenols are subjected to enzymatic oxidation, the fresh leaves give off green grass smell and the aroma of the tea leaves is increased;before fixation, the tea leaves are subjected to rocking and blanching, so the bitter and astringent taste of the tea leaves can be reduced, the amino acid content is increased and the freshness is improved; and the Longjing tea containing herba dendrobii has the effects of reinforcing the stomach, promoting the production of the body fluid, quenching thirst, nourishing yin, resolving heat, alleviating pain, relieving asthma, preventing cough, dredging and clearing deficient heat, diminishing inflammation, removing toxins, strengthening the spleen and stomach, eliminating dampness, dispellingcold, strengthening the bones and muscles, eliminating halitosis, promoting digestion, resolving greasiness, refreshing and benefiting mind, resisting oxidation, resisting halmatogenesis, resisting tumor, reducing the content of cholesterol and low-density lipoprotein in the blood, inhibiting blood pressure rise, inhibiting platelet agglutination, resisting bacteria and resisting product allergy.
