Abstract
It is to acquire green tea old leaf and the cellulase that is added during rubbing after tea green-keeping is rubbed and then spread and finishes again the invention discloses a kind of processing method of high-quality green tea；Tealeaves is added papain and secondary rub and then spread and finish again after water-removing；Tealeaves addition pectase is rubbed three times and then spread after water-removing finishes again；Other techniques are carried out according to conventional green tea processing method, the cell component in tealeaves can be made to be easier to dissolve out, increase the content of millet paste extract, theanine, tea polysaccharide, reduce polyphenol content, tea leaf quality and mouthfeel are significantly improved, green tea obtained gives off a strong fragrance, mouthfeel is fresh and sweet, and soup look is bright, and operation is simple, conducive to the economic benefit for improving tealeaves.
Description
Technical field
The invention belongs to tea processing field, and in particular to a kind of processing method of green tea.
Background technique
Green tea is a kind of azymic tea, using the suitable new bud-leaf of tea tree as raw material, is spread, is finished, rubbed, shaping, done
The techniques such as dry refine, and include the inorganic elements such as abundant carrotene, vitamin A, calcium, phosphorus and a variety of amino acid, and have only
Special flavour.Green tea, which not only quenches one's thirst, refreshes oneself, and also has good replenishing body fluid and clearing away heat pathogen, anti-inflammation and sterilization, strong bone and unfolds blood vessel etc.
Effect makes it also obtain great welcome in the international market.However, as the improvement of people's living standards, to tealeaves product
The content requirement of matter, mouthfeel and its nutritional ingredient is also higher and higher, and tea polyphenols are a kind of effective antioxidant, however due to
Contain more tea polyphenols, less theanine and polysaccharose substance in green tea, and then bitter taste in its drinking process caused to be laid particular stress on,
Mouthfeel is bad.It is low output, at high cost currently, the acquisition of existing green tea is generally made with two leaves and a bud.Therefore, change and pass
System Green tea processing technology develops a kind of processing method for making green tea with old leaf and effectively improving green tea quality and mouthfeel, for
The expansion in green tea market, the promotion of economic benefit all have great importance.
Summary of the invention
The purpose of the present invention is to provide a kind of processing method of high-quality green tea, Green Tea Polyphenols content obtained is low,
And theanine and caffeine content are high, give off a strong fragrance, mouthfeel is fresh and sweet, soup look is bright, effectively improves tea leaf quality.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of processing method of high-quality green tea, acquisition green tea old leaf are spread, are finished；Rubbing after tea green-keeping
Addition cellulase is rubbed and then spread in the process finishes again；Tealeaves is added papain and carries out secondary rub after water-removing
It twists and then spreads and finish again；Tealeaves addition pectase is rubbed three times and then spread after water-removing finishes again.
Specifically comprise the following steps:
(1) acquisition of raw material: acquisition green tea old leaf, 4-12 leaf；
(2) spread: the blade of acquisition is disposed within, and 30 DEG C of room temperature, humidity 60%, space oxygen-supplying amount is often to stand
Square rice 0.5L/min, spreads time 6-8h, is lost leaf water part, and blade is wilted.
(3) it finishes: the blade after spreading being placed in roller fixation machine, 125 DEG C of water-removing 2-3min.
(4) cellulase solution that mass fraction is 0.5% is uniformly sprayed on the tealeaves after finishing, and rubs 3min；Rub end
Afterwards by tealeaves take out, mix, and it is evenly laid out it is disposed in bamboo plaque spread, tealeaves spreads with a thickness of 3cm, room temperature 30
DEG C, humidity 75%, space oxygen-supplying amount is every cubic metre of 0.8L/min, spreads time 30min；Tealeaves after spreading is placed in rolling
In cylinder green-keeping machine, 125 DEG C of water-removing 1min.
(5) tealeaves after finishing uniformly squirts the Papain enzyme solution that mass fraction is 0.45%, rubs 2min；Rub knot
After beam by tealeaves take out, mix, and it is evenly laid out it is disposed in bamboo plaque spread, tealeaves spreads with a thickness of 3cm, room temperature
36 DEG C, humidity 75%, space oxygen-supplying amount is every cubic metre of 0.8L/min, spreads time 30min；Tealeaves after spreading is placed in
In roller fixation machine, 125 DEG C of water-removing 1min.
(6) tealeaves after finishing uniformly squirts the pectase liquid that mass fraction is 0.7%, rubs 2min；It will after rubbing
Tealeaves takes out, mixes, and it is evenly laid out it is disposed in bamboo plaque spread, tealeaves spreads with a thickness of 3cm, 36 DEG C of room temperature,
Humidity is 75%, and space oxygen-supplying amount is every cubic metre of 0.8L/min, spreads time 30min；Tealeaves after spreading is placed in roller to kill
In green machine, 125 DEG C of water-removing 1.5min.
(7) tealeaves after finishing carries out shaping and drying according to conventional green tea manufacturing procedure, and a kind of high-quality green tea is made.
The cellulase solution of addition and the mass ratio of tealeaves are 0.2:1-0.3:1.
The Papain enzyme solution of addition and the mass ratio of tealeaves are 0.1:1-0.2:1；The pectase liquid of addition and tealeaves
Mass ratio is 0.1:1-0.15:1.
Remarkable advantage of the invention is:
The present invention innovates on the basis of conventional green tea processing technology, and discarded green tea old leaf is recycled
The green tea of high-quality is made.Key problem in technology is that old leaf spreads the processing of control and high microsteping green tea during rubbing, such as
The process of rubbing of green tea after water-removing is carried out in three times, rubs addition cellulase solution for the first time, rubs addition wood for the second time
Melon liquid of protease rubs addition pectase liquid for the third time, and takes the enzyme activity of lossing that finishes step by step, not only effectively keeps original green tea
Flavor, while increasing the dissolution rate of cell component in tealeaves, increase the content of millet paste extract, theanine, tea polysaccharide, reduce
Polyphenol content, hence it is evident that improve tea leaf quality, green tea obtained gives off a strong fragrance, mouthfeel is fresh and sweet, and soup look is bright, and easy to operate easy
Row, conducive to the economic benefit for improving tealeaves.Millet paste extract, theanine, tea polysaccharide in tealeaves produced by the present invention after testing
Content improve 32.4%, 14.7%, 18.3% compared with traditional tealeaves, polyphenol content reduces by 35.6%.
