Description
Technical field
The present invention relates to tealeaves manufacture technology field, and in particular to a kind of preparation method of green tea.
Background technology
Green tea has unique color and luster, fragrance, sense of taste, moulding, has significant physiologically active, is a kind of best natural
Healthy beverage.Contain a variety of nutrition such as Tea Polyphenols, tea polysaccharide, caffeine, protein, amino acid, vitamin, mineral matter in tealeaves
And pharmaceutical component, this is the material base of tealeaves biological action, and mineral matter, dimension life not only can be directly supplemented by drinking tea
The nutrients such as element, amino acid, and the anti-oxidation active substances such as Tea Polyphenols can be taken in, comprehensive Physiological effect is produced to body
Effect.Although green tea has pharmacological action and the healthcare functions such as anti-oxidant, anti-aging, anti-cancer, anticancer, sterilization, anti-inflammatory, meanwhile,
Also nervous centralis can be stimulated containing alkaloids such as caffeines, influence sleep, increase blood pressure, the illness for improving rheumatism arthritis
Rate, mutagenesis and the composition for causing the effects such as baby's premature labor.At present except the technology of caffeine is mainly used in instant tea and liquid
Body beverage, the technology applied to traditional tea is less, or can remain poisonous organic solvent, or can destroy the damage of tealeaves flavor
Lose, or complex operation, or cost height.
Selenium is animal and the essential nutrient element of people, has cancer-resisting, prevents Keshan disease, Kaschin-Beck disease, cardiovascular disease,
Anti-aging, release the effect such as heavy metal toxicity.The full selenium concentration of soil that China has 73% is less than 0.02mg/Kg, belong to selenium deficiency or
Low selenium area, it is too low to result in Selenium In Foods content.Many endemic illness, such as Keshan disease, Kaschin-Beck disease, cancer, heart and brain blood
The diseases such as pipe and immunity of organisms decline and aging course etc. are relevant with selenium intake deficiency in meals, mainly due to these
The selenium that the people in area absorb from local food is inadequate.Selenium element is strengthened by food approach, it has also become feature is eaten at present
One of study hotspot of product.
For green tea as a kind of traditional economy crop, selenium content itself is not high, develops a kind of selenium-rich and content of caffeine is low
Green tea, integrate nutrition, safety, health care, there is important value to green tea health food development, it may have great city
Field prospect.
The content of the invention
The goal of the invention of the present invention is, in view of the above-mentioned problems, providing a kind of preparation method of green tea, reduces caffeine etc. no
Sharp composition, improves Se content, and the green tea of making integrates nutrition, safety, health care, has higher market value.
To reach above-mentioned purpose, the technical solution adopted in the present invention is：
A kind of preparation method of green tea, comprises the following steps：

Gently stirred once every 10~15 minutes, to fresh leaf loss of weight 20%~30%.
S3, fixing：Using water-acetic acid steam beating, then by fresh leaf 35~50 DEG C of 5~10min of bubble of warm water, will finish
Fresh leaf afterwards is pulled out from water, is shaken loose and is spread out and rejects heat to 25 DEG C~30 DEG C.
S4, knead：By in the water-removing leaves input kneading machine of step S3 processing, kneaded according to light-weight-light mode
Pressurization, time of kneading is 25~40min.
S5, manage bar：Tea leaf vibration manage bar after first being kneaded under the conditions of 200~220 DEG C is into streak, then using electricity
The multi-functional trimmer of heat 25~30min of shaping under the conditions of 120~160 DEG C by tealeaves.
S5, drying：Tealeaves after manage bar is placed on tea tray, is put into dryer and dries.
S6, Titian：By in the tealeaves input fragrance extracting machine after drying, 8~10min of Titian, is carried under the conditions of 110~130 DEG C
Moisture content≤5.5% of tealeaves after perfume (or spice).
S7, cryopreservation：Tealeaves finished product after Titian is packaged, places freezer storage.
As a kind of preferable scheme, in step S1, the selenium fertilizer is humic acid selenium titanium fertilizer, the quality percentage of its each component
It is than content：Instant capacity humic acid is 70%, urea phosphate 25%, and phosphoric acid selenium potassium is 2.5~3%, and titanyl sulfate is 2~3%,
During sprinkling, it is watered 40~50kg with 100 grams of humic acid selenium titanium fertilizer and is uniformly sprayed at tea tree blade face.
As a kind of preferable scheme, in step S3, fixing temperature control is at 180~200 DEG C, pH3.5~5.5, fixing
3~5min of time.
As a kind of preferable scheme, in step S3, the fresh leaf after fixing is delivered to again second is carried out in caldron type water-removing machine
Secondary fixing, fixing temperature control is at 220 DEG C~230 DEG C, and passage time is 1~2 minute, the fresh leaf after then second is finished
Spreading for cooling, fast cooling is to 25 DEG C~30 DEG C.
As a kind of preferable scheme, in step S4, the concrete operations kneaded are：Loosening pressure 1min, pressurize 3min, so
Loosening pressure 1min again afterwards, according to this circular treatment.
As a kind of preferable scheme, in step S5, first with mesh belt dryer by tealeaves under the conditions of 100~120 DEG C just
Dry 3-5min, then 2~3h of spreading for cooling, then 10~15min is dried again under the conditions of 90~110 DEG C.
Due to using above-mentioned technical proposal, the invention has the advantages that：
1. the preparation method of the present invention, to tea tree foliage spray selenium rich water solution before tea picking, after fertilising 8~15 days again
Fresh leaf is gathered, fresh leaf is fully absorbed selenium fertilizer, so as to improve the selenium content of tealeaves.Make consumer necessary by supply human body of drinking tea
Trace elements of selenium, play a role in health care.
2. tealeaves of the present invention utilizes water-acetic acid steam beating, the unfavorable compositions such as caffeine are reduced, improve tea-leaf safety.
Meanwhile using secondary fixing, improve the quality of tealeaves.The green tea of making integrates nutrition, safety, health care, has higher
Market value.
