Abstract

The invention relates to preparation methods for blueberry scent green tea and blueberry black tea. The preparation method of the blueberry scent green tea comprises the following steps of (1) tea base treatment; (2) blueberry leaf treatment; (3) scenting; (4) heat dissipation; (5) re-heaping up and scenting; (6) holding-out of scented flowers; (7) baking; (8) flower lifting; and (9) holding-out of scented flowers. The preparation method of the blueberry black tea comprises the following steps of (1) rolling, (2) fermentation and (3) baking. The preparation methods are characterized in that the blueberry leaf treatment is treated through a shaking technology; leaves are taken as flowers and are used as scenting raw materials for the blueberry scent green tea; in the scenting stage, tea leaves are covered with a tea bag, so that heat dissipation and holding-out of the scented flowers are facilitated; due to a one-scenting and one-lifting technology, the technology is simple and feasible; the blueberry leaves for scenting and lifting can be prepared into blueberry black tea, so that the utilization rate of a resource is increased. The blueberry scent green tea prepared from baked green tea and the fresh blueberry leaves has fresh blueberry scent; the tea liquor is brightly olivine; a person drinking the blueberry scent green tea can feel the flower scent, and the blueberry scent green tea tastes delicious.

Problems solved by technology

However, there are few types of flowers suitable for making scented tea in the north, mainly honeysuckle and osmanthus. The raw materials are not abundant, and they are not easy to pick, so it is difficult to develop scented tea. How to obtain local materials, "use leaves as flowers", and make full use of blueberry leaves to develop new tea products , would be a good way to
