Description
Technical field
The present invention relates to the system in the technology field of tea bag, more particularly to the low packed pulverizing tea of caffeine fruity
Preparation Method.
Background technology
Caffeine in tealeaves accounts for the 2%~5% of its dry, and it can promote central nervous excitation, promote blood
Circulation, acceleration heartbeat, relaxing smooth muscle, promotion gastrointestinal secretion, enhancing subtotal hepatectomy etc..Therefore caffeine can be sensitive to some
Crowd brings adverse effect, for example, easily inducing children ADHD, triggers Patients with geriatric cardiovascular and cerebrovascular diseases cerebral thrombus or miocardial infarction, makes pregnant
Woman's gestosis, causes neonate disabled, causes climacteric women insomnia, paramenia, causes middle-aged and old calcium deficiency etc..Mesh
Before, for liquid charging stocks such as tealeaves leaching liquors, caffeine mainly is removed using column chromatography technology, this technology is applied to work
In the production of industry metaplasia.But for traditional curable type tealeaves, mainly there are Hot water extraction and supercritical carbon dioxide fluid extraction, though Hot water extraction
It is so simple and easy to apply, but wastewater treatment load is big, and will also result in while caffein-free the functional components such as Tea Polyphenols
It is lost in.
Supercritical carbon dioxide fluid extraction selectivity is strong, safe operation, but Tea Polyphenols and fragrance component can also have in caffein-free
Loss in various degree, obtained more into the fresh refreshing degree reduction of tea, current SCF-CO 2 equipment is expensive, it is difficult at home
Applied in small enterprise.Therefore a kind of caffeine removal methods for traditional curable type tealeaves are developed significant.
The present invention will study a kind of tealeaves tea bag of offer, in the case where not influenceing Tea Polyphenols to lose, pass through removing
Caffeine, improves the health degree of tealeaves in favor of the selection of more crowds.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of tealeaves fragment for removing caffeine, sealed by permeable bag
Dress, lowers the excitability of tealeaves, is adapted to the preparation side of the low packed pulverizing tea of caffeine fruity that the people of more multiple-age bracket drinks
Method.
The present invention is realized by following technological means solves above-mentioned technical problem：
A kind of low packed pulverizing tea of caffeine fruity, using fresh tea passes (moisture 74.23%, Tea Polyphenols 25.84%, coffee
Coffee alkali 3.82%, total free amino acid 1.18%, water extraction 46.67%) prepare, because caffeine is soluble in more than 80 DEG C heat
Water, so from the heating water bath mode water extraction caffeine of 80~100 DEG C of temperature range, rise temperature is conducive to the leaching of caffeine
Go out.This method fresh tea passes are higher than the caffeine removal efficiency of stem tea, and fresh tea leaf water content is high, and it is dry relative to stem tea
Heavy burder liquor ratio is big so that the caffeine removal efficiency of fresh tea passes is big.In addition fresh tea passes and the cyto-architectural difference of stem tea may
It is that one of the reason for causing this different, fresh tea passes have complete eucaryotic cell structure, and caffeine is mobility in vacuole, because
And with selective penetrated property, the catechin of macromolecular can be hindered in a short time, and the stem tea through kneading its cell knot
Structure is destroyed, caffeine and Tea Polyphenols due to dehydration reason cell inwall also in relation with even closer, be not easy it
Leach in a short time.Caffeine and Tea Polyphenols are present in cyto-architectural vacuole, and the aqueous solution can be swelled tea cell,
Improve mass transfer situation of the caffeine in tealeaves.Confirmed through overtesting：The removal efficiency of fresh tea passes caffeine is in solid-liquid ratio up to 1: 10
(g/mL) it is optimal.The most suitable solid-liquid ratio of fresh tea passes is 1: 10 (g/mL), and the higher moisture content of fresh tea passes is to cause this difference
Main cause.
If being only simultaneously pure water extraction, the removal efficiency of fresh tea passes caffeine is only 50% or so, if addition one
Quantitative Tea Polyphenols, can greatly increase the removal efficiency of caffeine in tealeaves after extraction.Moreover, with Tea Polyphenols aqueous solution mass body
The removal efficiency of caffeine also increases therewith in the increase of fraction, tea sample.Because Tea Polyphenols can be tied in many ways with caffeine
Close, this combination can increase the dissolution trend of caffeine in tea cell, so that increasing for Tea Polyphenols amount can make coffee in the aqueous solution
The amount that coffee alkali is leached increases.The complete eucaryotic cell structure of fresh tea passes itself just can prevent intracellular catechin to divide greatly in a short time
Son is leached, and in the case of containing Tea Polyphenols in extraneous solution, more can effectively retain the Tea Polyphenols in tealeaves, relative increase coffee
The dissolution trend of coffee alkali.This can be explained in the low concentration Tea Polyphenols aqueous solution well.Fresh tea passes optimum extraction condition is:Temperature
80~100 DEG C, solid-liquid ratio 1: 6~10 (g/mL), Tea Polyphenols aqueous solution quality volume fraction 5~8%, 5~10min of time.This
Under the conditions of caffeine removal efficiency up to more than 80%, be higher by 30%, and Tea Polyphenols free of losses than conventional hot water extraction.Tea Polyphenols water
Solution extraction can be effectively reduced the caffeine content in tealeaves, be effectively retained or improve main function composition in tealeaves
The amount of Tea Polyphenols.
Caffeine is extracted using the aqueous solution of Tea Polyphenols, caffeine can be largely removed, improve the product of tealeaves
Matter, but 80% recovery rate of the above is built upon on the premise of tealeaves passes through dissolved destruction by tealeaves epicutile wax in advance,
The problem all existed by tealeaves of plant leaf blade is that the surface of plant leaf blade all has coating of wax matter layer, belongs to hydrophobic,
The dissolution of tea juice in immersion process is influenceed, the surface wax to tealeaves by the way of harmless is invented and pre-processes, invention is adopted
Method is to utilize solid-liquid ratio 1:Sodium bicarbonate (the NaHCO of the 5~10% of 20~303) solution to tealeaves advance immersion 50~
80min, then adds fine sand with respect to total amount 3~6%, 4~10min of stirring, after the completion of pull tealeaves out and dry, microexamination can be with
It was found that the surface epidermis wax of tealeaves manifests the destruction of different levels by destruction.
Invention is not the tealeaves of traditional sense, but what the tealeaves fragment for passing through pulverization process after tea-manufacturing technology was packed
Tea bag, for the pursuit suited one's taste, the tealeaves that invention carried out pretreatment to surface sprays juice extraction thing, allows juice extraction
Liquid diverging is penetrated into tealeaves, dissolution while immersion, so that reaching improves the purpose of mouthfeel.Participate in the material of juice extracting
Material has：Apple, banana, matrimony vine, skim milk, honey, Rosa Damascana, jasmine petal, grape wine, ginseng, apple, the thing such as banana
Material is first squeezed the juice, and is then diluted with water 5~10 times of dilutions, the surface of tealeaves is then sprayed in the form of spraying, after air-drying
Secondary spraying is carried out, for carrying out 2~3 operations, is finally dried, tealeaves particle, splitting encapsulation is ground into.
Beneficial effects of the present invention：Invention is removed to the caffeine in tealeaves, the tealeaves is adapted to more ages
The crowd of section, reduces the excitant and excitability of tealeaves, improves the quality of tealeaves, to human body with health, and extracting method is profit
Combination suction-operated with Tea Polyphenols to caffeine, while caffeine is fully absorbed, retains the guarantor to Tea Polyphenols in Tea
Shield, and without worrying the loss of Tea Polyphenols, finally, tealeaves of the invention and without the process kneaded, the final form of tealeaves
It is that disintegrating slag after particle, immersion in teacup is less.
