Abstract
The invention discloses a kind of dendrobium candidum black tea and preparation method thereof, by both dendrobium candidum extract solution and black tea with 1:The weight part ratio complex configuration of (5 10) complements each other into dendrobium candidum black tea, both dendrobium candidum extract solution and black tea, farthest remains the nutritional ingredient in dendrobium candidum, drinks for a long time, can reach lipid-loweringing, the effect of strengthen immunity.
Description
Technical field
The present invention relates to food processing field, and in particular to a kind of dendrobium candidum black tea and preparation method thereof.
Background technology
Dendrobium candidum (scientific name：DendrobiumofficinaleKimuraetMigo), also known as ribbed hedyotis herb, micro- specific item is belonged to,
The perennial herbaceous plant that grows nonparasitically upon another plant of orchid family, is distributed mainly on the ground such as Chinese Anhui, Zhejiang, Fujian.Its stem is used as medicine, in category tonic
Yin tonics.Dendrobium candidum have promote the production of body fluid, it is hypoglycemic, enhancing immunity of organisms the effects such as.Between Katyuan year the Tang Dynasty《Taoist Scriptures》Iron
The skin stem of noble dendrobium is classified as first of nine big celestial grass.Tea product species in the market about dendrobium candidum is various, and is combined with black tea
Then have not seen, and most of dendrobium officinale tea select be all dendrobium candidum stem, leaf or flower, easily cause in manufacturing process
The loss of nutrition inside dendrobium candidum, healthy nutritive value is low, causes the waste of resource.
The content of the invention
To solve the above problems, the invention provides a kind of dendrobium candidum black tea and preparation method thereof, by dendrobium candidum and
Both black teas are combined, and are farthest remained the nutritional ingredient in dendrobium candidum, are drunk for a long time, can reach lipid-loweringing, enhancing
The effect of immunity.
The present invention is achieved by the following scheme：
A kind of dendrobium candidum black tea, it is characterised in that the dendrobium candidum black tea is pressed by dendrobium candidum extract solution and black tea
1:The weight part ratio complex configuration of (5-10) is formed, mainly including following preparation process：
(1) 1 is pressed:The weight part ratio of (5-10) gets dendrobium candidum extract solution and black tea ready；
(2) by dendrobium candidum extract solution and black tea mixed fermentation；
(3) obtained dendrobium candidum black tea first product after fermentation is dried；
(4) dry dendrobium candidum black tea is subjected to pressure brick finished product.
It is preferred that, the preparation method of the dendrobium candidum extract solution is：
(1) dendrobium candidum by fresh harvesting is cleaned, and is crushed, and is crossed 30-50 mesh sieves, is obtained dendrobium candidum powder；
(2) dendrobium candidum powder obtained by step (1) is added in the 70-80% ethanol solutions of 5-6 times of parts by weight, immersion
Refluxing extraction 2-3 times under the conditions of 12-15h, 60-80 DEG C, each 1.5-2h, filtering, merging filtrate；
(3) 10-15min is centrifuged under the conditions of the filtrate for obtaining step (2), 4000-5000r/min, supernatant concentration is taken
Discharged to relative density for 1.1-1.25.
It is preferred that, the method for the mixed fermentation of the step (2) is：By black tea homogeneous reactor in slighing on pad, thickness 10-
20cm, dendrobium candidum extract solution is divided 3 times and is uniformly sprayed in black tea, is capped diablement fort, the turning of 2-3h back after sprinkling every time
Side is sprayed, and stacks 10-15h.
It is preferred that, the drying means of the step (3) is：By the dendrobium candidum black tea after fermentation, vacuum refrigeration is positioned over
In drying machine, -30-50 DEG C are first cooled the temperature to, rate of temperature fall is 5 DEG C/min, and 4-6h is incubated after freezing；It is evacuated to 5-
10Pa；50-65 DEG C is heated to, 10-12h dischargings are dried.
The present invention has selected the extract solution of dendrobium candidum, at utmost remains its active ingredient, while with extract solution
Form moistens tea in invisible, will not occur the aesthetic feeling of the whole cup tea of particle influence of dendrobium candidum when making tea.
Fermentation stage, water is replaced from dendrobium candidum extract solution, can both be met the moisture needed for tea leaf fermentation process, again may be used
The extract solution of dendrobium candidum and black tea leaf just are sufficiently mixed into fermentation initial stage in fermentation, its mouthfeel and nutriture value are greatly improved
Value.
From traditional Exposure to Sunlight, fire is roasting, electric oven is dry etc., and mode is different, can present invention employs the mode of vacuum freeze drying
To reduce the loss of volatile ingredient, the nutritious composition in tealeaves Central Plains is kept；It is dried in the state of tealeaves freezes, can be with
The complete structure of tealeaves is kept, is not in the generation of the phenomenons such as fracture, powder, dried tealeaves is loose porous, when drinking
Can quick brewing, tealeaves is unfolded, millet paste is bright orange；Vacuum freeze drying, can remove more than 95% moisture content, enables tealeaves long-term
Preserve without mutagens matter.
The invention has the advantages that：Rapid and convenient is brewed, tealeaves unfolds attractive in appearance, the thorough bright orange no-sundries of millet paste,
Mouthfeel alcohol just, is for a long time drunk can lipid-loweringing, strengthen immunity.
