Description

A kind of preparation method of dendrobium tea
Technical field
The present invention relates to technical field of traditional Chinese medicines, particularly relate to a kind of preparation method of dendrobium tea.
Background technology
Dendrobium tea is the health protection tea of mainly making take the stem of noble dendrobium as raw material.Mostly most of dendrobium tea of the prior art be to be obtained by the stem of noble dendrobium and other Chinese herbal medicine compatibilities, and its each self-corresponding preparation method also more impropriety, easily causes the problems such as nutritive loss, quality reduce, health-care effect is undesirable.
A kind of dendrobium tea as disclosed in CN101695328A, is by 3~7 parts of the stems of noble dendrobium, 2~3 parts of gynostemma pentaphylla, and 3~7 parts of Mao Xu Caos, 3~7 parts of tealeaves, 3~5 parts, sugar is made; Concrete method for making is existing the stem of noble dendrobium, gynostemma pentaphylla to be soaked 8~12 hours, and heating is boiled 1~3 hour, adds afterwards tealeaves, Mao Xu Cao, continues to boil 1~3 hour, filters to obtain filtrate for the first time; In filter residue, discharge water and boil 1~2 hour, filter and obtain filtrate for the second time; In filter residue, discharge water again and boil 0.5~1 hour, filter and obtain filtrate for the third time; Merge three times filtrate, be condensed into medicinal extract, add sugar to mix, technique is made pharmaceutically acceptable preparation or food and drink routinely, obtains dendrobium tea.The deficiency of this scheme is in raw material tea, except the stem of noble dendrobium, to also have gynostemma pentaphylla, Mao Xu Cao, tealeaves and sugar, and taste is more complicated; Preparation method also has improper part, and long soaking time easily causes water soluble vitamin, inorganic salts stripping, in the process of boiling in heating, causes nutritive loss, reduces nutritive value, even causes medicinal material rotten.
The and for example disclosed a kind of dendrobium officinale health tea of CN102293286BA, be by freshly harvested come fresh dendrobium candidum, pine needle, the leaf of bamboo, fresh Randia canthioides leaf and withe dry cleaning and dry surperficial moisture, the weight ratio of four kinds of raw materials is respectively 1: 2.5: 2.5: 1, then using dendrobium candidum as raw material 1, add again the mountain spring water of filtration of 10.5 times of dendrobium candidum weight to decoct, when temperature arrives 100 ℃, decocting time 60~90 minutes, decoction liquor is cooled to normal temperature, after filtration, obtains preparation 1; Secondly, pine needle and the leaf of bamboo are mixed, as raw material 2,3, add the mountain spring water of filtration of 3.2 times of raw material 2,3 gross weights to decoct extraction, decoct 100 ℃ of water temperatures, 40~50 minutes time, be then cooled to normal temperature and also filter and obtain preparation 2,3; Again, add the clean fresh Randia canthioides leaf drying and 5.5 times of withe dry weight to filter mountain spring water, decoct extraction, extracting temperature is 100 ℃, and 25~35 minutes time, cold filtration, obtains the preparation 4 that contains natural antiseptic agent and pigment; Finally, above-mentioned preparation 1, preparation 2,3 and preparation 4 are mixed, and with the mountain spring water after filter sterilization by 0.5~1 times of mixed liquor dilution, by 5% and 0.1% of the total formulation weight amount after dilution, add honey and preservative sodium benzoate, filling after sterilization again.The deficiency of this scheme is, preparation method is too complicated, and in final product, contains anticorrisive agent, has reduced nutritive value and the edibility of product.
For another example disclosed dendrobium tea of CN103431127A and preparation method thereof, by clean stem of noble dendrobium stem after drying through section, hug sth. made by twisting, cure and make the dendrobium tea that the length of strip or sheet or curling sheet is less than 35 millimeters; Stoving temperature is 50 degree~110 degree, and the time of curing is 1 hour to 10 hours.The deficiency of this scheme is, bakes and banks up with earth excess Temperature, easily causes nutritive loss; The time of curing is shorter, is unfavorable for Titian.
Summary of the invention
In order to solve the problems of the technologies described above, the object of the present invention is to provide a kind of preparation method of dendrobium tea, solved in prior art the medicinal ingredient of dendrobium tea impure, method for making is improper causes the problems such as nutritive loss, quality reduce, health-care effect is undesirable.
The invention provides following technical scheme:
A preparation method for dendrobium tea, is to make as raw material take the stem of noble dendrobium, comprises the following steps:
(1) stem of noble dendrobium is gathered afterwash, segment, cures 60~70 ℃ of temperature, 16~18 hours time by constant temperature drying room;
(2) carry out Microwave Treatment after going out drying room, approximately 2.5~3min, obtains dry tea again;
(3) the dry tea of step (2) gained is added to 4~8 times of water gagings, with NaOH, regulate pH=7~9, decoct 1~3h, collect filtrate, filter residue adds 3~6 times of water gagings again, decocts 0.5~2h, collects filtrate, merging filtrate;
(4) step (3) gained filtrate being concentrated into relative density at 70~80 ℃ is 1.1~1.2, adds ethanol to containing alcohol amount 65%~75%;
(5) standing 12~48h, filters, and gets supernatant and reclaims ethanol concentrated, obtains Herba Dendrobii extract;
(6) pulverize after adopting fluidized bed drying or microwave drying, cross 40~60 mesh sieves, pack gauze bag into, in 0.15MPa, 121 ℃ of high pressure steam sterilization 20min, are distributed into paper bag for bag tea after being cooled to room temperature, and sealing, obtains tea in bag.
The preparation method of above-mentioned a kind of dendrobium tea, also can, by gained filtrate evaporation and concentration in step (3) to medicinal extract, then in vacuum belt-type dryer, be dried to dry extract, then granulation, compressing tablet obtain plain sheet, finally plain sheet is carried out to film coating, obtain tea buccal tablet.
The preparation method of above-mentioned a kind of dendrobium tea, also can make fine particle by the Herba Dendrobii extract in step (5), and packing, makes tea electuary.
The preparation method of above-mentioned a kind of dendrobium tea, gained filtrate in step (3) is concentrated, at the temperature of 4~10 ℃, refrigerate 6~24h, get supernatant, add the pure water dilution of 30~100 times of supernatant volumes, filter, then boiling sterilization, filling, obtain cold tea.
Beneficial effect of the present invention: preparation method is scientific and reasonable, simple, production continuity is strong, and the medicinal tea type of acquisition is abundant, and the purity of Herba Dendrobii extract is high; Bake and bank up with earth temperature height moderate, time length is suitable, can reach good Titian effect, and can retain to greatest extent the effective medicinal components of dendrobium tea, improves nutritive value.Adopt the dendrobium tea that makes of the inventive method, have reinforcing stomach reg fluid, nourishing Yin and clearing heat, anti-ageing, improve the effects such as immunity, and have be easy to carry about with one, easy to use, the natural feature such as pure.
