Abstract
The invention discloses a kind of bark of eucommia function black tea preparation method.The folium cortex eucommiae in 7 October is used as raw material, by selecting, washing, drying, finishing, cutting, knead, fermenting, stoving process, it has been fabricated to the strong black tea of delicate fragrance, not only have the unique taste, by chemical examination, contain chlorogenic acid, Jing Pingni sweet acid isoreactivity compositions in tea, have the dual characteristicses of tea product and healthcare function concurrently.
Description
Technical field
The present invention relates to function black tea preparing technical field, more particularly to a kind of bark of eucommia function black tea preparation method.
Background technology
Folium cortex eucommiae is the leaf of gutta-percha tree harvesting.The raw material to be made black tea by spreading the leaves on withering racks to dry using folium cortex eucommiae typically uses the leaf of green sprouting
Bud, but the raw material is before and after Clear and Bright（4-5 months）Harvesting, it is seasonal strong, yield poorly.
Using spring leaf tea, raw material is seasonal by force, and harvesting is few, causes cost higher, and detects in leaf bud and live through analysis
Property composition is low.
In addition, when traditional encomia black tea makes, fixing processing is not carried out, but because hold in folium cortex eucommiae containing a kind of
Easily by the oxidizing ferment of active ingredient breaks down in folium cortex eucommiae, the enzyme could be inactivated by green removing in high temperature, reduce activity in folium cortex eucommiae
The decomposition of composition, meanwhile, the blue or green taste in folium cortex eucommiae also only eliminates at high temperature.
Existing encomia black tea does not carry out fixing processing, is easily crushed during kneading, and secondly holds during the fermentation
Sentimental taste easily is carried, influences the mouthfeel and quality of tea.
Therefore, existing encomia black tea preparation technology how is improved, while the mouthfeel and quality of tea is improved, improves Du
The content of active component in Zhong Ye, is the technical problem to be solved in the present invention.
The content of the invention
The present invention provides a kind of bark of eucommia function black tea preparation method aiming at above-mentioned defect.Using the 7-10 months
Part folium cortex eucommiae be raw material, by selecting, washing, drying, finishing, cutting, knead, fermenting, stoving process, be fabricated to delicate fragrance
Strong black tea, not only has the unique taste, and by chemical examination, contains chlorogenic acid, Jing Pingni sweet acid isoreactivity compositions in tea, has tea concurrently
The dual characteristicses of product and healthcare function.
A kind of bark of eucommia function black tea preparation method technical scheme of the present invention is the folium cortex eucommiae for using 7-10 months for original
Material, by selecting, washing, drying, finishing, cutting, knead, fermenting, baking step, it is fabricated to bark of eucommia function black tea.
A kind of bark of eucommia function black tea preparation method, comprises the following steps：
（1）7-10 months harvest the leaf of gutta-percha tree；
（2）The folium cortex eucommiae of harvesting is selected, will be mouldy, rotten leaf is picked out；
（3）Cleaned into washing equipment, wash away the dust sticked on leaf；
（4）After being collected to the leaf after washing, it is placed on the bed that dries in the air and is dried, until the moisture of blade surface dries completely；
（5）Leaf after drying is entered into green-keeping machine, fixing temperature is at 200-250 DEG C；Fixing uses 6SCT-50 green-keeping machines, kills
Blue or green purpose：Fresh leaf partial moisture is evaporated, tealeaves is softened, is easy to knead shaping, while foul smell, promotes good fragrance
Formed.After fixing, brittle leaf gradually becomes to contain flexible, will not be crushed during kneading, easily into strips.
（6）Kneading machine is entered back into, strip is presented in 20-25min, the leaf after kneading in time of kneading；
（7）Rear leaf will be kneaded and be put into fermentation machine, fermentation temperature is controlled at 60-90 DEG C；
（8）Leaf is moved into baking oven again after fermentation, control drying temperature is at 100 DEG C.
Step（4）In, the moisture of described blade surface dries completely, and water content is in 50-60%.
Step（5）Preheated specifically, first opening green-keeping machine, and design temperature works as green-keeping machine at 200 DEG C to 250 DEG C
Temperature reach preset temperature after, by leaf be sent into green-keeping machine fixing, by green-keeping machine time 0.5-2min, blade gradually becomes
It is soft, and rich in toughness.
Step（6）In, fermentation humidity is in 70%-80%, and fermentation time is in 4-6h.
Step（8）In, drying time 6-8h.
Beneficial effects of the present invention are：The functional black tea that the present invention obtains, it is not only in good taste, and contain various active
Composition, it is a kind of higher health beverages of value.And using bark of eucommia great Ye as raw material, raw material is easy to get, and cost is low, tea output rate is high.
Embodiment：
For a better understanding of the present invention, technical scheme is described in detail with instantiation below, but it is of the invention
It is not limited thereto.
Embodiment 1
Bark of eucommia great Ye will be harvested 7-10 months first to be selected, will be mouldy, rotten leaf is picked out, subsequently into washing
Equipment is cleaned, and washes away the dust sticked on leaf, and use winnowing machine drying surface moisture；Leaf after drying is placed on
Dry in the air and dried on bed, until the moisture of blade surface dries completely（Water content is in 50-60%）, first open green-keeping machine and carry out in advance
Heat, and leaf after the temperature of green-keeping machine reaches preset temperature, is sent into 6SCT-50 fixings by design temperature at 200 to 250 DEG C
Machine finishes, and by green-keeping machine time 0.5-2min, blade gradually softens, and rich in toughness.6CR-45 kneading machines are entered back into, are kneaded
Strip is presented in 20-25min, the leaf after kneading；Rear leaf will be kneaded and be put into fermentation machine, fermentation temperature is controlled at 60-90 DEG C, hair
