Abstract
A kind of production method of stem of noble dendrobium black tea of the present invention carries out room temperature and withers, can avoid being conducive into caused by direct high-temperature hot-air withers the active principle conversion of tea quality not exclusively, the stem of noble dendrobium yellow leaf the problem of；Medium temperature hot wind, which withers, can further promote to be conducive into the stem of noble dendrobium leaf conversion of tea quality substance, while stem of noble dendrobium blade green grass gas being made to scatter and disappear completely；The advanced fast chartered plane of recycling of tentatively rubbing carries out secondary rub when rubbing, the clasmatosis of stem of noble dendrobium leaf can be made to obtain evenly, make the fermentation of stem of noble dendrobium leaf evenly, while making the cell wall rupture of stem of noble dendrobium leaf epidermis corneocyte, intracellular active ingredient fully releases；Temperature is rationally controlled when drying, the temperature of drying carries out two-wheeled drying from low to high, avoids the problem that drying rate is too fast, the excessively high tea that causes into of temperature generates burnt fiery taste.
Description
Technical field
The present invention relates to tea processing technical fields, and in particular to a kind of production method of stem of noble dendrobium black tea.
Background technology
Fresh stem of noble dendrobium clearing heat and promoting fluid power is strong, and warm disease and evil is joined the army blood, and high fever dysphoria with smothery sensation person when using, mend clearly as length by dendrobium chrysanthum enriching yin,
Pyreticosis later stage, yin deficiency abnormal heat person are suitable.Dendrobium candidum, HERBA DENDROBII, the efficacy of a drug is stronger, Dendrobidium huoshanness, is suitable for old man void people, yin-fluid
Insufficient person, earrings dendrobium promote the production of body fluid without cold and cool, with generation tea, Appetizing spleen-tonifying.Modern chemistry and pharmacological research show iron sheet stone
The principle active component of dry measure used in former times is polysaccharide, and polyoses content is up to 20%~30%.Because contained by it dendrobium polysaccharide, alkaloid, amino acid,
There is the ingredients such as trace element the immunocompetence of enhancing body, anti-oxidant, anti-aging to reduce blood glucose, nourishing Yin and promoting production of body fluid, strong kidney benefit
Essence inhibits tumour cell, alleviates the unique effects such as physical fatigue.But since dendrobium officinale is mainly grown in high and steep mountains
Overhanging cliff on, because its seed is minimum, thin such as dust and without endosperm, germination rate is extremely low under field conditions (factors), natural resources
It is very rare.In addition uncontrolled digging throughout the year, wild resource is increasingly exhausted, and natural production cannot meet existing market demand.
Dendrobium candidum maple bucket mostly is made using the cane of dendrobium candidum in the market, and the leaf of dendrobium candidum is leather due to it
Matter shape leaf, the epidermal cell wall thickness of leaf, cuticula is flourishing, and the active ingredient that dendrobium candidum leaf includes is difficult to release, therefore
The active ingredient in dendrobium candidum leaf is difficult to be utilized at present.
Invention content
