Problems solved by technology

[0012] Aiming at the problems that the existing willow leaf tea has a certain coldness and is prone to green and astringent bitter taste and the color of the tea soup is too light when drinking, while the existing black tea has the functions of lowering blood fat and improving gastrointestinal function, but the effect is not obvious, etc., The present invention provides a kind of fermentation using the coronoid saccharomyces, which can not only solve the green and astringent bitterness in willow leaf tea, but also solve the cold and cold defect of willow leaf tea with black tea, and ensure the tea leaves are fermented. A tea processing method that has good flower uniformity, is easy to drink, can maintain the original quality of traditional fermented tea and retain functional ingredients to the greatest extent

Embodiment 1

[0034] Use a sprayer to spray 20L of 40% tea polyphenol solution on 100kg of dry black hair tea raw materials, stir and mix, control the temperature at 75~80℃, the relative humidity of the air at 80%~85%, and pile it for 8h; use 100~ Steam steam at 106°C for 5-10 seconds; spray 20kg of P. cristatum spore powder on the steam-treated tea leaves, stir them evenly, and place them in a rectangular container with a lid, vacuum degas for 20 minutes, and The rectangular container with lid is wrapped and sealed with a fresh-keeping bag, and then steam sterilized with steam at 100~115℃ for 5 minutes; after steam sterilization, the rectangular container with lid is placed in the air with a relative humidity of 70~85% and a temperature of 30~35℃. The fermentation time is 36h. After the fermentation process, 50 kg of black hair tea and 28 kg of golden willow leaf tea are mixed and pressed into tea bricks, they are placed in the air with a relative humidity of 50-65% and a temperature of 30-...

Embodiment 1

[0036] Spray 20L of 40% tea polyphenol solution on 100kg of dried black hair tea with a sprayer and mix with 56kg of Jinliuye tea. After stirring and mixing, the temperature is controlled at 75~80℃, and the relative humidity of the air is 80%~85%. Pile for 8h; steam with 100~106℃ steam for 5~10 seconds; spray 20kg of spore powder of Pseudocystis cristatum on the steamed tea leaves, stir evenly, press into tea bricks, and use a cover Place the rectangular container and vacuum degas for 20 minutes. The rectangular container with lid is wrapped and sealed with a fresh-keeping bag, and then steam sterilized with steam at 100~115℃ for 5 minutes; after steam sterilization, the rectangular container with lid is placed in the air with a relative humidity of 50~ 65%, temperature is 30~35℃, fermentation time is 7 days. The long-term fermentation mixture is treated in an infrared drying oven (model 404-1 produced by Shanghai Hu Yueming Scientific Instrument Co., Ltd.) for 30 minutes, and ...

Abstract

The invention provides a technology for utilizing cyclocarya paliurus leaves and raw dark green tea for fermentation to make healthcare tea. A functionality tea product is obtained through the steps of pile fermentation, secondary fermentation, infrared ray fixing and the like. By means of the secondary fermentation mode, leaching speed of steam sterilization to cyclocarya paliurus leaf tea can be reduced, conversion of polysaccharide substances in the cyclocarya paliurus leaves is also effectively restrained, functionality ingredients of the cyclocarya paliurus leaves are also retained while the mouthfeel of tea soup is improved, reaction with tea polyphenols is avoided, uniform growth of golden flowers can be ensured, and quality of the composite tea is improved. A large amount of eurotium cristatum spore powder is adopted for carrying out fast short-time fermentation and long-time fermentation, and the problem that the cyclocarya paliurus leaf tea is green, astringent and bitter is solved thoroughly; meanwhile, growth of infectious microbes is reduced, mildewing of raw dark green tea is avoided, and the influence on original flavor of the tea from a culture medium in eurotium cristatum liquid is avoided.

Description

Technical field [0001] The present invention mainly relates to a tea production, in particular to a process for making health-care tea by fermenting the golden willow leaf and black hair tea. Background technique [0002] Money willow, also known as green money willow, money tree, money tree. It belongs to the Juglans family, a deciduous tree, the tree is 10-30 meters high; the bark is gray; the branches are dark brown, the flowering period is 4 to 5 months, the leaves are leathery, and the singular pinnate compound leaves. The fruit sequence axis is 25 to 30 cm long, and the fruit has leathery horizontal disc-shaped wings. The fruit matures from July to September. [0003] Golden Willow leaves contain the original ecological hypoglycemic factor chain, which is mainly composed of two original ecological nutrients: inorganic nutrients and organic nutrients, which can effectively and comprehensively regulate human glucose metabolism. Organic nutrients: Golden Willow Tea is rich in ...
