Abstract
The present invention relates to a making technology for the extract of tea. The making technology has the technical structure that fresh and tender tea leaves are taken, foreign matter is removed, tea leaves are cleaned, and edible additives and clear water are added to the tea leaves and are mixed uniformly to be rolled into tea leaf pulp; residue is filtered, kieselguhr of which the weight is at least two times of the weight of the fresh and tender tea leaves is added to the tea leaf pulp, vacuum pumping filtration is carried out after the kieselguhr is dissolved, and the tea leaf pulp is heated to 80 DEG C to 95 DEG C. Compared with the prior art, the present invention has the advantages that components which are beneficial to human bodies are preserved in the fresh tea leaves, and meanwhile, the tea leaves are golden and transparent, and have few sediments, no turbid phenomena and fragrant and delicious taste sense.
Description
The present invention relates to a kind of manufacture craft of extract of tea, particularly a kind of manufacture craft that fresh tea leaf in its directly is processed into extract.
Applicant of the present invention had once applied for to Patent Office of the People's Republic of China that an application number was 91104943.6 on July 17th, 1991, name is called the patent of invention of " compound method of tea drink ", its technology constitutes: fresh tealeaves is selected, the removal of impurity, clean with the disinfectant rinsing, after adding an amount of edible additive and clear water and mixing, be rolled into the tealeaves slurry, and screen pack filters out residue.With the tea drink of this process processing, its color and luster is an aquamarine, and certain sediment is arranged in the tea drink, and is opaque, the sort of orange-yellow appearance in the traditional oolong teas water can not occur.
The objective of the invention is to overcome weak point of the prior art, and provide a kind of manufacture craft that fresh tea leaf in its directly is processed into extract of tea, not only can keep in the tealeaves active ingredient, and tea beverage is transparent orange-yellow appearance to the human body beneficial.
The objective of the invention is to reach by following approach.
A kind of manufacture craft of extract of tea, with fresh tea leaf in its through the removal of impurity, after the cleaning, add edible additive and clear water and mix, be rolled into the tealeaves slurry, and filter out residue, said fresh tea leaf in its is a kind of tender tealeaves, is incorporated as the diatomite of twice fresh tea leaf in its weight at least in the tealeaves slurry, after waiting to dissolve, carry out vacuumizing filtration, the tealeaves slurry is heated to 80 ℃～95 ℃.
Said edible additive can be a kind of salt, also can be white granulated sugar.
The said machine that tealeaves is rolled into tealeaves slurry can be a kind of tissue mashing machine, can be the combination of many machines such as a kind of pulverizer and a kind of squeezer also, can also be to utilize traditional pestle mortar that tealeaves is rolled into the tealeaves slurry.
Generally speaking, said edible additive and the method that tealeaves is rolled into tealeaves slurry is routine techniques.
It is more less to contain the chlorophyll composition in the tender tealeaves, and it is then more more to contain the lutein composition.Diatomite can adsorb chlorophyll and other sediment in the tealeaves slurry, and the tealeaves slurry is heated to 80 ℃～95 ℃, also be to be converted into lutein for the chlorophyll of accelerating in the tealeaves slurry, and the while also can reach the purpose of sterilization.
The handling procedure of tealeaves slurry preferably like this, filter with 60 orders～80 order screen packs earlier, filter with 200 orders～300 order screen packs again, in the tealeaves slurry, add said diatomite, carry out vacuumizing filtration with 700 orders～800 order filter papers, after tealeaves slurry heated by the said temperature of heating, be incubated 2～5 hours.
Like this, the tealeaves slurry is more transparent, and orange-yellow effect is more obvious.
Through the resulting tea juice of above-mentioned process, be needed extract of tea.
As preparing tea beverage, need in said tealeaves, adding weight be that the mineral water of 10～15 times of new fresh and tender tealeaves weight or the clear water after the process sterilization get final product only then.
And as to prepare instant tea, then only need said tea juice is concentrated and dry processing gets final product.The dry method of handling can be freeze drying, can be spray-drying also, and method for concentration can adopt reverse osmosis concentration.
In sum, the present invention has following advantage compared to existing technology: in human body beneficial's composition, golden yellow color is shinny, and is as clear as crystal in having preserved tealeaves, and sediment is few, does not have turbid phenomenon, and sense of taste delicate fragrance is good to eat.
Most preferred embodiment:
Take to pluck the new fresh and tender tealeaves that takes, selected, remove disease, worm, withered, blades such as Huang, and other impurity, behind edible liquid detergent thin up, clean tealeaves, use the clear water rinsing clean again, add with the clear water of weight such as tealeaves and be the millesimal edible salt of tealeaves weight, after the uniform mixing, then sending into tissue mashing machine's puddle rolls, 5～10 minutes, reach to pulpous state, make the cell membrane fragmentation in the tealeaves, medicinal ingredient and nutritional labeling are water-soluble, with 60 orders～80 purpose screen packs resulting tealeaves slurry is filtered subsequently, filter with 200 orders～3000 purpose screen packs again, inserting temperature through the tealeaves of above-mentioned twice filter slurry is to heat 1～2 minute in 85 ℃ the heat pot, be incubated after 3 hours, adding weight in the tealeaves slurry is the diatomite of 3 times of new fresh and tender tealeaves weight, waits to dissolve the back and carries out vacuumizing filtration with 700 orders～800 purpose filter papers, can obtain golden yellow bright tea juice after the filtration, add mineral water in tealeaves, its weight is 12 times of new fresh and tender tealeaves weight, promptly obtains the tea beverage that can cannedly come into the market.
Claims (1)
