Abstract
The present invention provides a kind of green tea extract and low-temperature extraction method, and extracting process at least includes：Place green tea into 0 DEG C ~ 4 DEG C of water and extract 3 ~ 5 hours, tea mass ratio is 1g：20g~70g.Time needed for greatly shortening cold extraction process using preparation method of the present invention, improve production efficiency, the extract excellent taste of preparation.
Description
Technical field
The present invention relates to a kind of green tea extract and its low-temperature extraction method.
Background technology
Tea, is the national drink of the Chinese nation.Nowadays, wide row is drunk tea in generation, and tealeaves has turned into consumes most, prevalence most extensively, most
A kind of worldwide health beverage for getting consumer reception.Recently, with the quickening of people's rhythm of life and in order to cater to young man
Consumption market, tea in the market occurs in that a kind of new mode of making tea, i.e. cold brew tea.Traditional cold brew tea, is that tealeaves is put into
7-8 hour of middle immersion in 5-10 DEG C of cold water.
Studies have found that, prolonged extraction, the production equipment of manufacturer cannot often meet, and cause production efficiency
Lowly, it is impossible to accomplish scale production；Research simultaneously is it has also been found that prolonged extracting process is also easy to cause various microorganisms
Grow, threatened to food security.
Green tea is the not fermented tea being made, and remains the natural materials of fresh leaf, Tea Polyphenols, catechin, the Ye Lv for containing
Element, caffeine, amino acid, vitamins and other nutritious components are also more.These natural nutrition compositions in green tea are to anti-aging, anti-
Cancer, anticancer, sterilization, anti-inflammatory etc. have special-effect, are less than other teas.
The content of the invention
The shortcoming of prior art in view of the above, it is an object of the invention to provide a kind of green tea extract and its low temperature
Extracting process, for solving deficiency of the prior art.
In order to achieve the above objects and other related objects, the present invention is provided and on the one hand provides a kind of green tea low-temperature extraction side
Method, the extracting process at least includes：Place green tea into 0 DEG C~4 DEG C of water and extract 3~5 hours, tea-water proportion is 1g：20g~
70g。
It refers to take Theaceae Camellia Plants tea Camellia sinensis O Ktunze that the green tea refers to
[Thea sinensis L.] young leaves or bud, not fermented, the drink made through techniques such as de-enzyme, shaping, drying.
The tea-water proportion is 1g：20g~70g refers to that the tea of every 1g is extracted using the water of 20g~50g.Preferred scheme
Can be extracted using the water of 30g~45g using the tea per 1g.
Preferably, the water uses mineral water.For example, Changbai Mountain mineral water can be selected.
Preferably, the time of the extraction is 3.5~4.5 hours.
Another aspect provides green tea extract prepared by above-mentioned green tea low-temperature extraction method.
It is used to prepare the purposes of green tea another aspect provides above-mentioned green tea extract.
Another aspect provides a kind of green tea beverage, comprising above-mentioned green tea extract.
The preparation method of green tea beverage, can use prior art, to adding appropriate water, additive in green tea extract
For example the component such as antioxidant, stabilizer, sugar, obtains by sterilized, filling.
Using in green tea beverage prepared by above-mentioned green tea extract, green tea extraction is contained in green tea beverage described in per 500ml
120~420ml of liquid.
It is highly preferred that containing 120~420ml of green tea extract in green tea beverage described in per 500ml
As described above, green tea extract of the invention and its low-temperature extraction method, have the advantages that：
Relative to the time that traditional handicraft greatly reduces extraction, the efficiency of production is improve, while the extraction of short time
The method of taking has kept away the growth of microorganism.Simultaneously using the green tea extract sweet mouthfeel of offer of the invention, local flavor is splendid.
Specific embodiment
Embodiments of the present invention are illustrated below by way of specific instantiation, those skilled in the art can be by this specification
Disclosed content understands other advantages of the invention and effect easily.The present invention can also be by specific realities different in addition
The mode of applying is embodied or practiced, the various details in this specification can also based on different viewpoints with application, without departing from
Various modifications or alterations are carried out under spirit of the invention.It should be clear that the not specific process equipment or device for indicating in the following example
Use conventional equipment or device in the art.In addition, it is to be understood that one or more method and steps mentioned in the present invention are simultaneously
Not repelling before and after the combination step can also have other method step or may be used also between the step of these are specifically mentioned
To insert other method step, unless otherwise indicated；It should also be understood that one or more the equipment/devices mentioned in the present invention it
Between combination annexation do not repel and can also there is other equipment/device before and after the unit equipment/device or at this
Other equipment/device can also be inserted between a little two equipment/devices for specifically mentioning, unless otherwise indicated.And, unless separately
It is described, the numbering of various method steps is only the convenient tool for differentiating various method steps, rather than to limit the row of various method steps
Row order limits enforceable scope of the invention, being altered or modified for its relativeness, and technology contents are being changed without essence
In the case of, when being also considered as enforceable category of the invention.
Extracting process：Green tea is added to the water, is extracted, obtain green tea extract.
Embodiment 1~5 and comparative example use the above method, set different extraction times, temperature and tea ratio,
The quality of O＆A extract.Professional is engaged to identify the quality of extract.
Green tea extract quality prepared by the embodiment 1~5 of table 1
Above-mentioned experiment shows that the green tea extract extracted using this method, fragrance is elegant, fresh taste, and aftertaste is sweet.
To Tea Polyphenols and the content of amino acid in above-described embodiment 1~5, the quality of green tea is further evaluated.
