Problems solved by technology

CN 101669561 B discloses a tea beverage with purple sweet potato leaves and blueberry leaves as main raw materials and a preparation method thereof. In the tea beverage, after mixing purple sweet potato leaves and blueberry leaves, the finished tea beverage is prepared by killing, kneading, and drying. Since the tea drink is made of purple sweet potato leaves and blueberry leaves, it cannot reflect the unique fragrance of blueberry leaves, and the blueberry leaves are destroyed and oxidized due to the use of 150-190°C for greening. In addition, the pH value of purple sweet potato leaves is higher than that of blueberry leaves. Mixing these two leaves will accelerate the decomposition of anthocyanins in blueberry leaves and reduce the amount of flowers in tea drinks. The content of cyanine weakens the health benefits of beverages

Embodiment 1

[0019] A kind of blueberry black tea, it is characterized in that: described blueberry black tea is to take blueberry leaf as raw material, prepares according to the following method:

[0020] 1) Fresh leaf picking: Pick fresh, pollution-free blueberry leaves to remove impurities and leaf water.

[0021] 2) Withering: place the blueberry leaves on a withering device such as a grain mat or a cloth mat, and carry out withering treatment. The thickness of the spread leaves is preferably 1-2 kg / square meter. 10%-15%, the withering ends.

[0022] When withering, avoid strong sunlight exposure. Moderately withered fresh leaves shrivel and become soft. The leaves feel soft when pinched by hands, without friction sound. The leaves form agglomerates when held tightly. When the hands are released, the leaves loosen slowly, and the leaves turn dark green. The scent of green grass fades, revealing the pleasant fragrance of withered leaves.

[0023] 3) Cell crushing: Put the withered b...

Abstract

The invention discloses blueberry black tea. Blueberry leaf blades serve as a raw material, and the blueberry black tea is prepared through the process of fresh leaf picking, withering, cell disruption, fermentation, roasting, shaping and drying and the like. The blueberry black tea does not contain caffeine, made tea water is savoury and mellow in taste and rich and gaudy in color, plenty of flavonoids are contained in the tea, and the blueberry black tea has the health care effects of restraining platelet aggregation, preventing thrombus and atherosclerosis, directly restraining generation of free radicals, preventing aging and being resistant to cancers and radiation and antiallergic and the like.

Description

Technical field [0001] The invention involves a drink, especially a blueberry tea drink made of fresh blueberry leaves. Background technique [0002] Blueberry (Blueberry) is more than oranges, alias, Blue Capita, Shan Sangzi, etc., which belongs to the genus plant of the Rhododendrona.Wild blueberry nutritional value is extremely high, and it is rare wild fruit. The anthocyanins (AnthoCyanosides), organic sag, organic selenium, cordin, amino acid, fruit acid and other special nutrients contained in blueberries are unmatched by any plant.In particular, biological flavonoids, referred to as OPC, have better physiological activity than general plant anthocyanins. Nutritional health foods with blueberry fruits are raw materials.After analysis and testing, blueberry leaves contain a large amount of vitamin C, OPC, SOD, anthocyanins and other ingredients that are beneficial to the human body, but the development and utilization of blueberry leaves in the existing technology are very f...
