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

Embodiment 1
[0034] The specific operation steps of preparing blueberry-flavored green tea are as follows:
[0035] 1) Tea base treatment: Select 20kg of high-quality baked green tea, refire the tea base at a temperature of 105°C, and take 10 minutes to spread and cool the tea base. The water content of the tea base is 3.2%, and the tea base is obtained;
[0036] 2) Blueberry leaf treatment: select 10kg of fresh blueberry leaves with one bud and three or four leaves, and cool them at a temperature of 25°C. The thickness of the fresh blueberry leaves is 3cm, and the cooling time is 60 minutes; Shake green rotating speed 15r / min, time 3min, make the fragrance of blueberry leaf distribute further, obtain the fragrant blueberry leaf of shaking;
[0037] 3) Scenting flowers: first take 4kg of tea base and wrap it into tea bags with gauze, spread the tea bags flat in the scenting flower box, so that the thickness of the tea base in the tea bag is 3cm; then take 2.5kg of fragrant blueberry leaves...

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. The finished blueberry black tea product is amber, and the tea liquor is brightly red; the blueberry black tea has the blueberry fruit flavor and tastes sour, sweet and refreshing.
