Description
Technical field
The present invention relates to tea fermentation technologies, more particularly to a kind of application of nanmu in tea fermentation technology.
Background technology
Fermentation is the key link of black tea process, and determines the core process of black tea quality.Fermentation essence is that fresh leaf is thin
Born of the same parents' tissue damage causes the enzymatic catalysis of polyphenol compound, and the chemistry that a series of complexity such as oxidations, polymerization, condensation occur becomes
Change process, to form the coloring matters such as theaflavin, thearubigin, theabrownin and alcohols, ketone, aldehydes, esters, carboxylic acids
The important substance of tea aroma and mouthfeel is influenced with phenols etc..Fermentation of black tea is in floor, bamboo basket, cootle mostly at present
It carries out, also there is the sale of full-automatic mechanical Zymolysis Equipment on the market.Traditional fermentation method is in addition to hygienic requirements cannot be guaranteed, ferment
Outside uneven, attenuation degree differs, the endoplasm and mouthfeel of black tea product are also different.From the point of view of existing achievement in research, hair
Ferment temperature, humidity, oxygen and fermentation time length are to influence the key factor of fermentation success or failure.And our team are passed through largely in fact
Discovery is trampled and compares, fermentation place and material also have black tea quality important influence.Common fermentation equipment has following defect：
（1）The material of general quality be not sufficiently stable it is especially wooden in it is certain dissolve in tealeaves during the fermentation at branch, to influence
Tealeaves mouthfeel and endoplasm, or even can have some poisonous and harmful substances.（2）Fermentation of black tea humidity is general usually all 90% or so
It is logical it is wooden easily corroded under this humidity throughout the year rotten, to cannot be lasting, or even jeopardize food security.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of nanmu answering in tea fermentation technology
With tealeaves is placed in the container made of leaflet hardwood nanmu and is fermented, the quality of tealeaves is improved.
The purpose of the present invention is achieved through the following technical solutions：A kind of nanmu answering in tea fermentation technology
With, which is characterized in that the tealeaves after rubbing is placed in the container made of leaflet hardwood nanmu and is fermented.
Preferably, further include before tealeaves being fermented：
Picking：Fresh leaf is picked, fresh leaf is free of rainwater or dew, and the picking season is summer, and plucking time is in 5 months, the last ten-days period, picking
When 20~24 DEG C of environment temperature, humidity be 60~65%；
It withers：The fresh leaf of picking is put into airing in withering trough, obtains the bud that withers；
It rubs：The cell tissue that active force destroys the bud that withers is applied to the bud that withers, bud shape of withering described in holding is complete.
Preferably, fresh leaf apparatus for placing when picking and/or withering trough are made of leaflet hardwood nanmu.
Preferably, the number to wither be twice or more, it is adjacent rub twice between further include spreading for cooling：To wither bud
It is put into spreading for cooling room, it is 3~5cm to spread thickness, controls 20~25 DEG C of room temperature, and humidity 90~95% spreads 20~30min.
Preferably, the spreading for cooling room is made of leaflet hardwood nanmu.
Preferably, the fermentation condition is：Ferment 90-150min under conditions of 25-30 DEG C.
Preferably, manage bar and shaping are carried out to the tealeaves after fermentation.
Preferably, the manage bar and apparatus for placing of tealeaves is made of leaflet hardwood nanmu when shaping.
Preferably, the tealeaves after fermentation is dried：Tealeaves after fermentation is placed on and is dried made of leaflet hardwood nanmu
It is dried in device.
Preferably, the water content of the sample tea after drying is 3~5%.
The beneficial effects of the invention are as follows：
（1）Tealeaves is placed in the container made of leaflet hardwood nanmu in the present invention and is fermented, due to leaflet hardwood nanmu stable material quality
It is durable, it is not easy septic yeast, poisonous and harmful substance will not be dissolved out, the quality of finished tea can be improved, meanwhile, container can be held
It uses long；
（2）Since the essential oil of leaflet hardwood nanmu is to 5 kinds of cancer cells such as leukemia HL-60 cell strain, lung cancer cell A-549 strain, and
Gram-negative bacteria and positive bacteria all have good inhibiting effect（IC50 is within 50ug/ml）, small during the fermentation
The essential oil vital essence of leaf hardwood nanmu is combined with tealeaves generation ingredient or combination reaction so that finished tea obtained has leaflet hardwood nanmu
The effect of essential oil vital essence；
（3）Tealeaves is held in preparation process by device made from leaflet hardwood nanmu, is neither easy to introduce new impurity, again
The time of contact that tealeaves and leaflet hardwood nanmu can be extended makes tealeaves and the essential oil vital essence of leaflet hardwood nanmu react, further carries
The high quality of finished tea.

Refering to fig. 1, the present invention provides a kind of application of nanmu in tea fermentation technology：
Embodiment one
As shown in Figure 1, a kind of application of nanmu in tea fermentation technology, includes the following steps：
S1. it picks：Fresh leaf is picked, fresh leaf is free of rainwater or dew, and the picking season is summer, and plucking time is in 5 months, the last ten-days period,
20~24 DEG C of environment temperature, humidity are 60~65% when picking.
The fresh leaf is one leaf of a bud or a bud two；Fresh leaf in the present invention can also use tender leaf.
When picking, the fresh leaf taken container made of leaflet hardwood nanmu is held, or is arranged one in container inner wall
Layer contact layer made of leaflet hardwood nanmu so that fresh leaf does not contact in a reservoir with other substances other than leaflet hardwood nanmu.
S2. it withers：The fresh leaf of picking is put into airing in withering trough, fresh leaf is made to dry out to obtain the bud that withers.It withers
Mode includes：Fresh leaf is put into withering trough and withers naturally by mode one, and temperature is 20~25 DEG C, and humidity is 65~75%, the time
For 7~10h, preferably 22~23 DEG C of temperature, humidity preferably 67~70%, time preferably 8~9h；Mode two, fresh leaf is put into and is withered
In slot, into fresh leaf, blowing hot-air withers, and the temperature of hot wind is 30~40 DEG C, and the duration is 20~35min, every 1~
5min is stirred once, preferably 35~37 DEG C, duration preferably 29~33min of temperature, overturns interval time preferably 2~3min.
The withering trough is made of leaflet hardwood nanmu.
The number to wither be twice or more, it is adjacent rub twice between further include the steps that spreading for cooling, the specific side of airing
Formula is：The bud that will wither is put into spreading for cooling room, and it is 3~5cm to spread thickness, and room temperature is 20~25 DEG C, and humidity is 90~95%, when spreading
Between be 20~30min, spread thickness preferably 3.5~4cm, preferably 22~23 DEG C of room temperature, humidity preferably 93~94% spreads the time
It is preferred that 25~27min, the airing room by leaflet hardwood nanmu be made or spreading for cooling room in the part surface that is contacted with tealeaves be provided with
The contact layer made of leaflet hardwood nanmu.
S3. it rubs：The cell tissue that active force destroys the bud that withers is applied to the bud that withers, bud shape of withering described in holding is complete
It is whole.During rubbing, the cell tissue for the bud that withers is destroyed, and tea juice is excessive, accelerates the enzymatic of polyphenol compound in tealeaves
Oxidation, is conducive to the progress of subsequent fermentation, and then improve the quality of finished tea.
The mode rubbed is to be rubbed by rolling machine or rubbed by hand, when being rubbed using rolling machine, is rubbed
