Embodiment 1

[0021] Add the old tea raw material water bath into pure water, extract its supernatant after centrifuging for 10min (centrifugal speed is 5000r / min); add an ethanol solution with a volume fraction of 50% to the supernatant to form a mixed solution A, Store at -15°C for 1 hour, centrifuge the mixture A when a curd-like precipitate appears, and take the sediment B at the bottom after centrifugation for 10 minutes; add the precipitate B to ethyl acetate for extraction to obtain the extracted Solution C: mix 100g of extract C, 350g of honeysuckle, 220g of chrysanthemum, 110g of mint, 140g of wolfberry, 70g of rose and 850g of pure water, boil and filter, and cool the filtrate to obtain the tea beverage A1.

Embodiment 2

[0023] Add the old tea raw material water bath into pure water, extract its supernatant after centrifuging for 15min (centrifugal speed is 8000r / min); add a volume fraction of 70% ethanol solution to the supernatant to form a mixed solution A, Store at -5°C for 2 hours, centrifuge the mixture A when a curd-like precipitate appears, and take the sediment B at the bottom after centrifugation for 15 minutes; add the precipitate B to ethyl acetate for extraction to obtain the extracted Solution C: mix 100g of extract C, 450g of honeysuckle, 260g of chrysanthemum, 140g of mint, 170g of wolfberry, 80g of rose and 900g of pure water, boil and filter, and cool the filtrate to obtain the tea beverage A2.

Embodiment 3

[0025] Add the old tea raw material water bath into pure water, extract its supernatant after centrifuging for 12min (centrifugal speed is 6500r / min); add an ethanol solution with a volume fraction of 60% to the supernatant to form a mixed solution A, Store at -10°C for 1.5h, centrifuge the mixture A when a curd-like precipitate appears, and take the sediment B at the bottom after centrifugation for 12min; add the precipitate B to ethyl acetate for extraction to obtain Extract C: mix 100g of extract C, 400g of honeysuckle, 245g of chrysanthemum, 125g of mint, 155g of wolfberry, 75g of rose and 870g of pure water, boil and filter, and cool the filtrate to obtain the tea beverage A3.

Abstract

The invention discloses a tea drink prepared from old tea and a process thereof. The process comprises the steps of adding an old tea raw material water bath to pure water, conducting centrifugation for 10-15 min, and then conducting supernate extraction; adding ethanol solution to supernate to form mixed liquid A, placing the mixed liquid A at a temperature ranging from -15 DEG C to -5 DEG C for 1-2 h, centrifuging the mixed liquid A when curdy precipitate appears, and obtaining bottom sediment B 10-15 min later; adding the sediment B to ethyl acetate for extraction to obtain extraction liquid C; mixing the extraction liquid C, honeysuckle flower, chrysanthemum flower, herba menthae, barbary wolfberry fruit, rose flower and pure water, conducting boiling and filtration in sequence, and cooling filtrate to obtain the tea drink. By making the tea drink from old tea, waste of old tea can be prevented, and the drink prepared from extracted tea polyphenol has a series of important pharmacological functions including resisting cancer, aging and radiation, clearing human body free radicals and reducing blood sugar level and blood fat.

Description

technical field [0001] The invention relates to tea beverages, in particular to a tea beverage prepared from aged tea and its technology. Background technique [0002] Tea is rich in a class of polyhydroxy phenolic compounds -. It is a new type of natural antioxidant and a class of polyphenolic compounds mainly composed of catechins. Its pharmacological function has very broad application prospects in the fields of oil, food, medicine, and daily chemicals. Tea contains 20%-30% tea polyphenols, and the extraction and application of tea polyphenols has become one of the hot topics in the development of "green projects" at home and abroad. At present, there is a huge demand for health care products with tea polyphenols as the main ingredient at home and abroad. The annual consumption in the United States is as high as 500t, and in Japan is 300-500t. The consumption in North America and Europe is also increasing year by year. my country is rich in tea resources, and a large a...
