Description
Technical field
It is more particularly to a kind of using closed extracter extraction the present invention relates to a kind of broken black tea extract and its extraction process
The technique for taking broken black tea.
Background technology
China is the native place of tea, is also the cradle of tea culture.Existing 4000 or the five thousand years history of discovery and utilization of Chinese tea,
And it is flourishing long time, spread all over the whole world.Tea is the drink of the whole nation of the Chinese nation, is sent out in the legendary god of farming, is heard in Lu Zhougong, emerging the Tang Dynasty, is contained in
Song Dynasty, when being popularized in Ming and Qing.
On the Classification of Tea of China, we can be classified as six major classes：It is green tea, black tea, white tea, oolong tea, yellow tea, black
Tea.Broken black tea is one kind of black tea, be by fresh tealeaves through it is wilting, knead after, with machine chopping be in granular pattern fragment, then
It is fermented, dry and be made, because its profile is in small, broken bits, therefore claim broken black tea, also referred to as " red thin tea ".For ease of drinking, often tumbler
Broken black tea be mounted in special filter paper bag, be processed into " tea bag ", bag connected when drinking and is brewed, leached with tea juice fast, leach
More completely feature.
However, the demand in order to meet consumers in general, in the market also has the beverage of some broken black teas, but conventional red
Tea extracting process yield is all less high, hence in so that the mouthfeel of the tea prepared is not mellow enough, local flavor is not also good.
Closed extracter is called multi-functional extracter, and in beverage industry, coffee, cereal, tealeaves etc. are mainly used at present
Extraction, its advantage is that system is closed, can reduce the loss of fragrance in extraction process.The extraction of current country's broken black tea beverage
It is mainly open hanging basket extraction to take mode, yet there are no the report of closed extraction,
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 broken black tea extract and its extraction
Taking technique, for solving deficiency of the prior art.
In order to achieve the above objects and other related objects, the present invention provides a kind of broken black tea extraction process, the extraction work
Skill at least comprises the following steps：
(1) by broken black tea and the closed extracter of water addition, the weight ratio of the broken black tea and water is 1:40~50, the extraction
It is 85 DEG C~95 DEG C to take temperature；The time of the extraction is 30~50 minutes, obtains extract；
(2) extract is filtered, centrifuges, produce broken black tea extract.
The broken black tea refer to by fresh tealeaves through it is wilting, knead after, with machine chopping be in granular pattern fragment, then
It is fermented, dry and be made, the tealeaves refers to for plant of theaceae tea Camellia sinensis (L.) O.Kuntze
The tender leaf of [Thea sinensis L.] or tender shoots.
The closed extracter can be the closed extracter of various manufacturer productions, and such as Taiwan Dongyuan County mechanical engineering is limited
The ES.EX.20.78. of company's production
Preferably, closed extracter is preheated before extraction in the step (1).
Preferably, the preheating time is 5-15 minutes, 85~95 DEG C during preheating temperature.
Preferably, before the extraction, the paddle for lifting closed extracter soaks the tea mixing of floating, then
Closed extracter paddle is dropped back into original position.
Preferably, the paddle of closed extracter is opened while extraction in the step (1), mixing speed is 20-
30 revs/min.
Preferably, the filtering in the step (2) uses rotary drum filter, and screen cloth selects 100-300 mesh, and flow control exists
20-30T/h。
It is highly preferred that through filtering bag filtration after rotary drum filtering, the mesh number of the filter bag is 80~200 mesh.
Preferably, the centrifugation in the step (2) uses disk plate centrifuge, the centrifugation flow 6000-16000L/h, pressure
Power 4.5-6.5bar, rotating speed about 7200-7300rpm.
Another aspect of the present invention provides broken black tea extract prepared by above-mentioned broken black tea extraction process.
Another aspect of the present invention provides the purposes for being used to prepare broken black tea beverage of above-mentioned broken black tea extract.
Another aspect of the present invention provides a kind of broken black tea beverage, and the broken black tea beverage uses broken black tea as described above
Extract is formulated.
Tea beverage is prepared using broken black tea extract, prior art can be used.Added into broken black tea extract appropriate
Water and food additives, by sterilization, can obtain.
As described above, the broken black tea extract and its extraction process of the present invention, have the advantages that：
Extraction process of the present invention is used to extract broken black tea yield height, total by determining extract soluble solid
Amount, it is found that extraction yield can reach 37.8%, therefore the nutritional ingredient and genuineness as much as possible for remaining broken black tea.
Tea beverage, excellent taste are prepared using broken black tea extract of the present invention.
