Tea-leaf power of the present invention is meant the meal of tealeaves, ultra-micro powder and nanometer powder.

Tea extract of the present invention is meant and adopts water extraction, water extraction and alcohol precipitation method, alcohol extracting method, overcritical---the resulting tea extract of carbonoxide extraction, the squeezing the juice of bright leaf, and concentrate, dry thing.

Additive of the present invention comprise flavor enhancement or (with) excipient or (with) colouring agent, the relative scale of additive in sifting tea be, flavor enhancement 0-10%, excipient 0.3-95%, and colouring agent is an amount of.Wherein, flavor enhancement includes sweetener, tasty agents, acid, the agent of tender flavor, and the relative scale of flavor enhancement in sifting tea is sweetener 0.5-2%, tasty agents 0.1-0.5%, acid 0.5-1%, tender flavor agent 0.5-1%.Excipient comprises filler, wetting agent, lubricant, adhesive, and percentage by weight contained in excipient is respectively, filler 0-98%, lubricant 0-2%, adhesive 0-95%, flavor enhancement 0.1-2%.Flavor enhancement in the above-mentioned excipient includes sweetener, acid and the agent of tender flavor, and their contained percentage by weights in flavor enhancement are respectively, sweetener 0-95%, acid 0-95%, tender flavor agent 0.5-20%.

The present invention has provided the preparation method of this instant tea tablet; promptly at the tea-leaf power of 0.5-99.7% (percentage by weight); or add the disintegrant of 0-85% in the mixture of tea-leaf power and tea extract (in dry) or the tea extract; and the flavor enhancement of adding 0-10%; the excipient of 0.3-95%; and an amount of colouring agent; under suitable humidity and temperature conditions; perhaps directly be pressed into tablet; perhaps granulate or granulation of non-water or dry granulation through wet earlier, form Formulation by the tablet press machine compacting again.

The present invention has pointed out that also this instant tea tablet can be used as leisure and health beverages.

The present invention has also pointed out the tealeaves function relevant health care purposes that this instant tea tablet preparation method can be used for and adopted.

In above-mentioned instant tea tablet, the effervesce sifting tea can comprise the instant disintegrant of one or more routine, and for example citric acid and sodium acid carbonate contain 0-85 weight % as every; Filler such as lactose, for example every contain 0-80 weight %, adhesive such as PVP, every contains 0-95 weight % lubricant, contains 0.1-2 weight % as every of stearic acid sugar.Although respectively organizing the example excipient, following development can form 100% heavy dissolving tablet with the tealeaves component, but, tablet can contain the flavor enhancement that routine is used for preparation in addition, colouring agent and form the effervesce sifting tea of 100% weight, for example instant sifting tea can comprise the disintegrant of the promotion dissolving of one or more routines, for example natural gum, cellulose derivative, polyvinylpyrrolidone and derivative thereof.The CMS or derivatives thereof; For example dispersing tablet can comprise a kind of meet water rapidly disintegration form the disintegrant of uniform sticky suspension, N-vinyl-2-Pyrrolidone for example, sodium carboxymethyl starch, the cross-linked polymeric CMC, L-HPC, CPVP, guar gum, Siberian cocklebur glue, alginates, pregelatinized starch, hydrophilic cellulose derivative.

Tea and tea extraction and flavor enhancement may be prepared altogether, and by closely mixing the formation tablet with adhesive or excipient, the advantage that this tablet brought is tea or tea extraction can be concentrated to minimum volume, is easy to carry aptly.

In above-mentioned instant tea tablet preparation method, tablet of the present invention can prepare by effervescent tablet, dissolving tablet or the Disket production method of routine.For example mix each component, granulate then, then prepare suitable sifting tea by tablet press machine.

The tea that is used as raw material among the present invention can be the dry tealeaves after the processing or the fresh tea passes of fresh harvesting.Stem tea can be ground into the tea powder that is fit to size particles by common pulverizer, also can become superfine tea powder or be broken into nano level tea powder, also can become superfine tea powder or be ground into nano level tea powder by ultramicro grinding by suitable way by ultramicro grinding by suitable way.The thickness of powder depends on the quality of the health herb tea of tea, the needs of characteristics and mouthfeel.The directly press for extracting juice method of bright leaf of tea is extracted the composition in the leaf, or pushes the extraction of squeezing the juice by adding an amount of water.Tea extract is meant that tealeaves extracts through water, or the press for extracting juice method that bright leaf extracts through decompression, concentrate, spray-drying forms.Or the water extract of tealeaves, add ethanol remove precipitation solution behind the part macromolecule impurity through recovered under reduced pressure, concentrate, spray-dired dry thing, or with the supercritical carbon dioxide extracting instrument to tealeaves extract, concentrate, the material of spray-drying gained.

The granulation of effervesce sifting tea can prepare by the method for granulating of routine.As wet granulation, for example acid ingredient and alkaline components are granulated respectively, before compressing tablet, mix, as the dry granulation compressing tablet, with roll extrusion or double compression granulation back compressing tablet; Granulate as non-water, component is granulated with on-aqueous liquid (as ethanol, isopropyl alcohol etc.) in will writing out a prescription; Direct tablet compressing for example, as select suitable component, with the mixture direct tablet compressing, and save granulation step.Equally preferably preparation preparation of the present invention under low-humidity environment for example is lower than 25%RH, is more suitable for being lower than 20%RH.For example humidity is low as far as possible with the effect of protection to extremely sensitive acid ingredient of humidity and carbonate in theory for the effervesce sifting tea.Same preferred temperature is controlled at 15-25 ℃, so also can avoid sugar in low melting point such as the tea extraction and the excipient of partly selecting for use such as polyethylene glycol softening.

The preferred instant sifting tea of the present invention is packaged in the airtight moisture-proof packaging material, and for example liner is with double-layer polyethylene, and other puts the common vessel of a pouch silica gel, preferably adopts thick metal forming lining with polyethylene.

The invention provides and a kind ofly be used for various uses instant tea tablet preparation method, as produce refreshing effect to the mind body-building, beauty treatment etc.

Advantage of the present invention is, invention and prepare finished product, carried forward the long tea culture of China energetically, go abroad for the tea beverage that China is traditional, go to the world and started a brand-new approach; Its multi-form, conveniently drinking way is accepted by contemporary people deeply; It is suitable on a large scale concentrating the preparation method of High-efficient Production further to guarantee the quality requirement of this sifting tea; This instant tea tablet has effectively overcome by the tealeaves sheet disintegration of routine preparation slowly or be difficult to dissolve the shortcoming of being brought, and makes it become comparatively desirable leisure beverage and health beverages.
