Description
Technical field
The present invention relates to Tea Processing technical field, and in particular to a kind of production technology of ultrafine green tea powder.
Background technology
The green tea powder middle age contains more Tea Polyphenols, is the auxiliary additive commonly used in food processing, and Tea Polyphenols is tealeaves
The general name of middle polyphenols, including flavanol compound, anthocyanin class, flavonoids, flavonols and phenolic acid class etc..Predominantly flavane
Alcohols, catechin accounts for 60~80%.Class material Tea Polyphenols, also known as tea tan or tea tannin, is the Main Ingredients and Appearance to form tealeaves color, smell and taste
One of, it is also have one of Main Ingredients and Appearance of healthcare function in tealeaves.Research shows that Tea Polyphenols isoreactivity material tool detoxifies and anti-spoke
The effect of penetrating, can effectively prevent radioactive substance from invading marrow, and strontium 90 and Co 60 can be made to excrete rapidly.Tea Polyphenols has
Stronger antioxidation, especially ester catechin EGCG, its reproducibility are even up to 100 times of the different bad hematic acid of L-.Tea Polyphenols
In addition to antioxidation, also with bacteriostasis, such as there is inhibitory action to staphylococcus, Escherichia coli, hay bacillus.
Peculiar smell in the adsorbable food of Tea Polyphenols, therefore with certain deodorization.There is protective effect to the pigment in food, it
Both natural pigment can be played a part of, can prevents food from fading again, Tea Polyphenols also has the formation and accumulation for suppressing nitrite
Effect.Existing green tea powder with the following drawback that the tea raw material of selection is relatively simple, and tealeaves contains in itself in actual production
Some leaf green are relatively low, and green tea powder green is thin, and the particle of green tea powder is larger, usually produce green tea only by crushing
Powder, green gas taste is heavier, the production of existing some green tea powders it is relatively costly.
The content of the invention
The technical problems to be solved by the invention are that a kind of color pool of offer is green, and chlorophyll retention rate is high, without green gas taste,
Particle is thin, the production technology of the low ultrafine green tea powder containing Tea Polyphenols of processing cost.
A kind of production technology of ultrafine green tea powder, it is characterised in that comprise the following steps,
1) tealeaves collection, tealeaves before acquisition more than 30 days when plantation of sheltering from heat or light is carried out to tea tree by shade net, harvesting
Preceding 10 shade net is removed, during collection, collection is sheltered from heat or light the young leaves grown after plantation；
2) fresh leaf spreads：Fresh tea leaf laying is placed into the upside of bamboo mat, and bamboo mat is placed into dry, ventilation sunshade
House in, 2~3 days duration；
3) protect green lands treatment：When fresh leaf spreads on bamboo mat to yoke, last layer green keeping agent is spread on the upside of tealeaves
The aqueous solution, the mass concentration of the green keeping agent aqueous solution is 5~10%, per unit area sprinkling green keeping agent aqueous solution 10ml, yoke
Bottom is provided with the blower fan for blowing to bamboo mat, and every 3~4 hours stir once fresh tea leaf；
4) finish；Tealeaves after protecting green lands is placed into steam inactivation machine and is finished；
5) knead；Tealeaves after de-enzyme is put into kneading machine and is kneaded；
6) block-separating and sifting；Sieved after the tea deblocking that will be kneaded；
7) stalk is taken off；Tealeaves after screening is ground into rubbing back and forth so that stalk departs from blade, sieves remove stalk again
Remove；
8) dehydrate；The blade of tealeaves is dried again, content water management is within 4%；
9) ultramicro grinding obtains green tea powder, crushes temperature control at 50~60 DEG C.
It is described protect green lands treatment when, tealeaves often stirs a tealeaves upper strata and all sprays the green keeping agent aqueous solution once.
Start firepower during described de-enzyme violent, as the moisture in tealeaves is gradually decreased, firepower will gradually weaken, not
Stir with stopping.
Stalk is prevented to be broken during described de- stalk.
Described tealeaves before acquisition 40 days when plantation of sheltering from heat or light, the preceding printing opacity for sheltering from heat or light for 10 days are carried out to tea tree by shade net
Rate is 40~50%, and the light transmittance for then sheltering from heat or light for 10 days is 70~80%, is 40~50% followed by the light transmittance that 10 days shelter from heat or light,
Then shade net was removed in 10 days.
Described green keeping agent by weight include following components, the weight portion of sodium chloride 5~10, the weight portion of Firebrake ZB 1~3,
The weight portion of copper weed floral leaf water extract 0.3~0.5 and the weight portion of vitamin C 1~2.
Described ultramicro grinding is by the way of ball mill grinding.
Green tea powder of the invention eliminates stalk so that the major part of green tea powder is all for the leaf subplate of tealeaves makes
Into, thus eliminate traditional stalk and cause coarse mouthfeel, bitter taste the shortcomings of.
The present invention in order to prevent the green tea powder there is green gas taste, condition, water content, the external force spread by optimal control fresh leaf
The mode of action and temperature process condition when crushing, so as to improve the quality of ultrafine green tea powder.
The present invention is tealeaves by way of plantation period has carried out sheltering from heat or light cultivation to tealeaves so that the tealeaves of harvesting contains
Leaf green very high, and blade is tender, and the stalk of particularly tealeaves is smaller, and stalk is easily removed, and green tea powder is more fine and smooth, bitter
Astringent taste is very light.
The present invention also takes special technology of protecting green lands during processing so that tealeaves can have leaf higher green
Plain retention rate, employs special green keeping agent, and green keeping agent of the invention contains sodium chloride, Firebrake ZB, copper weed floral leaf water extract
And vitamin C, the protection foliage green effect of tea can not only be played, but also with microelement-supplementing and other beneficiating ingredients
Effect.The growth of copper weed requires that soil copper content is especially high, the blue of its flower, it is necessary to absorb a large amount of copper ions to make colorful,
Therefore the copper weed floral leaf water extract of the application can provide the copper ion for protecting green lands, and copper weed also has relieving summer-heat, dissipate
The effect of wet water-filling, can complement each other with green tea powder, not result in side effect.
The beneficial effects of the invention are as follows：Beneficiating ingredient of the present invention is high, good health care effect, delicate mouthfeel, and taste is preferable, quality
Height, color pool is green, and chlorophyll retention rate is high, and without green gas taste, particle is thin, and processing cost is low.
