Abstract

The present invention discloses qi benefiting and heart tonifying instant tea and a preparation method thereof. The instant tea is characterized by being composed of the following raw materials in parts by weight: 400-420 parts of tea leaves, 10-11 parts of phaseolus angularis seeds, 8-10 parts of dried ginger, 4-5 parts of angelica sinensis, 2-3 parts of coptis chinensis, 9-11 parts of rehmannia glutinosa, 8-9 parts of ophiopogon japonicus, 11-12 parts of ziziphus jujuba, 4-5 parts of ginsengs, 7-8 parts of poria cocos, 10-11 parts of astragalus membranaceus, 9-10 parts of lophatherum gracile, 8-9 parts of red dates, 10-11 licorice, 30-40 parts of activated carbon, 45-46 parts of rapeseed oil, and 0.1-0.2 part of hydroxypropyl methylcellulose. The caffeine in tea water can be removed through activated carbon filtration, and a layer of film formed on the surface of the pretreated activated carbon can block flavor substances other than the caffeine in the tea water to be absorbed by the activated carbon. Besides, tea particles of the instant tea are enveloped using the hydroxypropyl methylcellulose, and thus the instant tea has a good moisture resistance, and can avoid caking due to moisture absorption during storage. In addition, the instant tea has effect of benefiting qi and tonifying heart.
