Abstract
The invention discloses a method for producing eucommia male flower tea, which comprises the steps of selecting eucommia male flowers, twisting for forming, quickly freezing, freezing and drying under vacuum, killing green and promoting fragrance, and cooling and sieving. In the invention, an ultralow-temperature quick freezing and low-temperature and vacuum freezing are adopted to dry the eucommia male flowers, so the active ingredients in the eucommia male flowers are hardly damaged; and the effect of the method is better than common tea preparation method. The eucommia male flower tea product prepared by the method is needle-like and green, and the shape of the eucommia male flower tea is almost the same as that before freezing. The tea water made by the tea prepared by the invention is green and orange, has a mellow flavor, and tastes sweet and agreeable and the aftertaste of the tea lasts long.
Description
Technical field:
The present invention relates to human lives's drink, relate in particular to a kind of processing method of tealeaves, particularly a kind of method of producing eucommia ulmoides male flower tea.
Background technology:
Drink tea in the history in existing several thousand of Chinese history, many tea-drinking product are lasting with its unique quality and function, and still, people's overwhelming majority of drinking tea all is that the leaf of tea tree is made.In plant, often fruit and the flower of most worthy.Eucommia ulmoides male flower tea is from the male flower of the Chinese medicine bark of eucommia, and its value is well imagined.Its medical value of the bark of eucommia almost is known to all in China, and All the world knows, and Compendium of Material Medica is early on the books, and that the bark of eucommia has is antiabortive, the function of step-down, nourishing liver and kidney, strong muscles and bones, and the male flower that comes from the bark of eucommia has good health care equally.The gutta-percha tree male and female are homophyletic not, and male flower that gutta-percha tree is opened comes off after finishing pollination under normal circumstances naturally, is not utilized.Generally at the eucommia Bark male flower full-bloom stage of 3-4 part in spring in every year, there is a large amount of male flowers to be wasted.The method that the leaf that utilizes tea prepares tealeaves is disclosed in No. 200610027428.0 patent applications of China.If adopt the way of former preparation tealeaves to process eucommia Bark male flower, can reduce the effect of eucommia Bark male flower, the water content of eucommia Bark male flower is higher, prepares jasmine tea with the method for preparing tealeaves, and is frangible, affects vision and sense organ.
Summary of the invention:
The object of the present invention is to provide a kind of method of producing eucommia ulmoides male flower tea, the method for described this production eucommia ulmoides male flower tea will solve the technical problem of the inapplicable processing eucommia Bark male flower of the method for preparing tealeaves in the prior art.
The method of this production eucommia ulmoides male flower tea of the present invention, comprise a step of choosing eucommia Bark male flower, it is characterized in that: after the described step of choosing eucommia Bark male flower is finished, carry out a step of eucommia Bark male flower being kneaded shaping, carry out again an eucommia Bark male flower after will kneading and be lower than the step of carrying out quick-frozen under-20 ℃ the temperature, the time of quick-frozen is between 3-24 hour, carry out again one the eucommia Bark male flower after the quick-frozen carried out vacuum drying step under freezing condition, in described vacuum drying step, temperature is lower than-20 ℃, the vacuum drying time is between 6～24 hours, carry out again the fragrant step that eucommia Bark male flower completed and urge, complete and urge fragrant temperature between 100～200 ℃, complete and urge the fragrant time between 1～10 minute, carry out again a step to completing and urging the eucommia Bark male flower behind the perfume (or spice) to cool off, carry out again the step of the cooled eucommia Bark male flower that sieves.
Further, described eucommia Bark male flower is selected from the pistil of eucommia Bark male flower, and the diameter of pistil is between 1.0～2.0 centimetres.
Further, also can be selected from bud or the pistil of eucommia Bark male flower and the mixture of bud of eucommia Bark male flower.
Further, after choosing eucommia Bark male flower, eucommia Bark male flower is carried out the airing drying, the time of airing is between 5～16 hours.
Further, the eucommia Bark male flower after will kneading is being lower than under-20 ℃ the temperature and is carrying out in the step of quick-frozen, and the temperature of quick-frozen is between-20 ℃ to-70 ℃.
Concrete, the eucommia Bark male flower after kneading is being lower than quick-frozen in the ultra low temperature freezer of-35 ℃ or-70 ℃.This step is very important, directly has influence on the quality of male flower tea finished product.
Further, eucommia Bark male flower after the quick-frozen is carried out vacuum freeze drying, eucommia Bark male flower is transferred in-50 to-35 ℃ the vacuum freeze drier and carries out drying, open vavuum pump, allow the gasification that directly distils of ice crystal in its male flower, reach the purpose of removing moisture in the eucommia flower by the mode that vacuumizes, vacuum freeze drying is whole removal moisture not, but can remove most of moisture, remaining water deficient is to have influence on following preparation process to the impact of tea product quality.
Concrete, transfer to vacuum freeze drier after, can take to allow it continue freezing 0.5～2 hour, prevent that melt on the male flower surface in the transfer process, impact distillation gasification result.
Further, to complete and urge perfume (or spice) after the step cooled off of eucommia Bark male flower in, in Electric heat oven, complete and urge perfume (or spice), temperature is between 100～200 ℃ in the Electric heat oven, the time was at 1～10 minute.Temperature and time control is very important, deals with improperly, the tea product blackout occurs, or does not produce fragrance, or produce empyreumatic taste.
Further, sieve and remove the smalls that idol in the operating process has generation.
The present invention and prior art are compared, and its effect is actively with obvious.The present invention adopts super low temperature quick frozen and cryogenic vacuum freeze drying eucommia Bark male flower and prepares high-grade tea, almost completely kept its active ingredient, active ingredient contained in the eucommia Bark male flower is destroyed hardly, and its effect is better than now common tealeaves preparation method greatly.Eucommia Bark male flower tea product likeness in form needle-like, the look prepared are green, and be similar with freezing front shape.With the tea that the tea of the method preparation is infused, its color greenbelt orange, aromatic taste, sweet reward mouth is enjoyed endless aftertastes.The development and utilization eucommia Bark male flower can be created more society and economic benefit, is a large Gospel for vast farmers, and refuse becomes treasured, creates larger added value.Eucommia Bark male flower is made tea, and its fragrance is very tempting, adds the medical value of the bark of eucommia itself, and its eucommia Bark male flower is made tea, will become treasure in the tea.
