Abstract
A gingko tea for preventing and treating cardiovascular and cerebrovascular diseases is prepared from the leaf buds of gingko through picking up, spreading, heating, kneading and drying.
Description
[technical field] the present invention relates to a kind of improvement and succedaneum of Folium Camelliae sinensis, particularly belongs to a kind of Folium Ginkgo tea and processing technology thereof.
[background technology] drinks tea, and is that people associate important form and the content with amusement in daily life.For majority, drinking tea has the effect of health preserving body-building.But, along with people to healthy pay attention to day by day, people wish to reach by drinking tea the purpose that is of illnesses and fitness, and this effect of common tea is not obvious.So in conjunction with the traditional Chinese medical theory of China, emerging many in the market is the health tea of raw material with Folium Ginkgo, Folium Crataegi, dry Flos Chrysanthemi etc.But, existing Folium Ginkgo tea, the taste bitterness has influenced the cognition degree of consumer to a great extent, is difficult to generally promote, and can not really become the succedaneum of Folium Camelliae sinensis.By analysis, this bitter taste is in the course of processing of Folium Ginkgo, causes owing to processing technique is unreasonable.In addition, because the Folium Ginkgo tea that existing market is sold do not have strict qualification on selecting materials, selected a large amount of old leaves for use, because its cell wall, cell membrane lignifying, no longer have the natural medical curative effect of Folium Ginkgo, cause the medical value of existing Folium Ginkgo tea to exhaust.
[summary of the invention] purpose of the present invention promptly is to disclose a kind of Folium Ginkgo tea and processing technology thereof, with improvement and the succedaneum that a kind of Folium Camelliae sinensis is provided, not only meets the custom that people drink tea but also can give full play to the purpose that the Folium Ginkgo natural medical is worth thereby reach.
Folium Ginkgo tea disclosed in this invention are characterised in that, it makes raw material is the first Semen Ginkgo leaf bud of exhibition, and are through harvesting, spreading for cooling, complete, knead, dry and make streak cured leaf, promptly drinkable after brewing with boiled water.
The processing technology of Folium Ginkgo tea disclosed in this invention comprises harvesting, spreading for cooling, completes, kneads and dries, and it is characterized in that:
(1) pluck: germinate from the ginkgo branch began in 2～4 days, and the Semen Ginkgo leaf bud of plucking blade face exhibition just is as the tea making raw material, and is standby.General sustainable 10～20 days of harvesting process is treated that the blade face is black, when beginning lignifying, is promptly stopped to pluck.
(2) spreading for cooling: will pluck that the Semen Ginkgo leaf bud that comes is put to the sunlight abundance, ventilated, make thinner in the place of dried and clean, dry in the sun; Generally will continue 12～48 hours, thick, moisture content scatters and disappears, weight reduces at 1/4～1/3 o'clock and stops to treat to wither its blade face;
(3) complete: use tea water-removing machine, under 200 ℃～260 ℃ temperature, the Semen Ginkgo leaf bud through spreading for cooling is completed; The process control that completes presents bright-coloured green 50～60 seconds, blade face is advisable, and avoids the blade face to become gloomy color; Through the Semen Ginkgo leaf bud that completes, moisture content scatters and disappears and accounts for 1/6～1/7 of its weight.
(4) knead: will spread out through the Semen Ginkgo leaf bud that completes, and dispel the heat to room temperature, and put into tea twisting machine, heavily rub 10～15 minutes, visual being stops when streak.
Complete for (5) two times: will put into tea water-removing machine again through the Semen Ginkgo leaf bud of kneading, and under 80 ℃～120 ℃ temperature, carry out two times and complete, and continue 5～10 minutes, the moisture content that evenly scatters and disappears is particularly removed and is kneaded the juice that squeezes out in the process.
Knead for (6) two times: will spread out through the Semen Ginkgo leaf bud that completes for two times, and dispel the heat, and put into tea twisting machine again, heavily rub 5～10 minutes, to repeat appearance to room temperature.
(7) oven dry: will put into tea making dedicated drying machine through the Semen Ginkgo leaf bud of kneading for two times, constantly moving drying under 120 ℃～150 ℃ temperature with handspring, until between leaf dry adhesion, stop when producing fragrance.
(8) two times oven dry: will make thinner through the Semen Ginkgo leaf bud of oven dry, be cooled to room temperature, put into tea making dedicated drying machine again and carry out two times oven dry, under 120 ℃～150 ℃ temperature, stir with quick-moving speed, further reduce moisture content, the control water content stopped at 8%～10% o'clock.At this moment, fragrance increases
(9) three times oven dry: will make thinner through the Semen Ginkgo leaf bud of two times oven dry, be cooled to room temperature, put into tea making dedicated drying machine again, under 120 ℃～160 ℃ temperature, stir with quick-moving speed, carry out three times oven dry with further raising fragrance, and reduce moisture content, the control water content stopped at 4%～6% o'clock.
(10) packing: will make thinner through the Semen Ginkgo leaf bud of three times oven dry, be cooled to room temperature, reject relic and impurity, pack, promptly make Folium Ginkgo tea disclosed in this invention.
Tea making raw material of the present invention---Folium Ginkgo, on pharmacology, have invigorate blood circulation, the analgesic effect, as: " practical Chinese herbal medicine complete works " according in December, 1999 publication of Harbin publishing house put down in writing: Folium Ginkgo, " little hardship; property is flat, have invigorate blood circulation, the function of pain relieving and reduce the effect of serum cholesterol, coronary artery dilator.Cure mainly hypertension, coronary arteriosclerotic angina pectoris, hypercholesterolemia disease, dysentery, elephatiasis.”。Because processing technology that the present invention taked, more traditional tea-manufacturing technology is divided into more step again, and the moisture content that scatters and disappears equably in the course of processing has been avoided bright leaf sap at high temperature to turn sour, degenerate and generated bitter taste.In addition, the persistent period of each step is shorter relatively, avoided destruction and loss to its contained active component, therefore, product of the present invention is drunk conveniently, mouthfeel is good, the fragrance height endures repeated infusions, and is ideal Folium Camelliae sinensis succedaneum, and have the Folium Ginkgo natural medical and be worth, prevention and treatment cardiovascular and cerebrovascular disease are had good effect.
