Abstract
The invention discloses a method for preparing instant black tea powder. The method comprises the steps of withering fresh tea, freezing, rolling and cutting, crushing through ultrasonic wave, fermenting, extracting, filtering, concentrating and drying. Through the freezing treatment, the tea cell walls show brittle state; the tea cell walls are effectively impacted and broken completely by rolling, cutting and processing through ultrasonic wave, so that effective components such as amino acid, microelements and the like encircled in the tea cell walls are effectively leached at a quick leaching speed efficiently; the prepared instant black tea can be dissolved in water with a temperature higher than 5 DEG C; liquor color is clear, transparent and fragrant and the taste is sweet. The method for preparing instant black tea powder is simple, easy to operate, low in cost and applicable to industrial mass production.
Description
Technical field
The invention belongs to Food Engineering Development field, relate generally to a kind of method of preparing instant black tea powder.
Background technology
The kind of instant tea mainly contains instant black tea, instant green tea, instant sented tea etc.The advantage of instant tea maximum is that dissolution velocity is effective soon, instant-drink, and nutritive and health protection components is concentrated, and portably uses conveniently the embarrassment can also avoid directly having tea time in tealeaves tape entry and inconvenience.The processing method of existing instant tea mostly is raw material through water boiling and extraction, then by concentrated and dry, obtains having the instant tea of certain nutrition health-care functions.
Instant black tea powder is as the one in instant tea, and it has the effects such as hypotensive, hypoglycemic, reducing blood lipid, anti-oxidant, anticancer, anti-ageing, anti-AIDS, has become the most popular drink in the whole world.Chinese tea beverage market development speed exceedes 300%, becomes the fourth-largest drink that is only second to soda, water, milk beverage.The instant black tea powder sold in the market, be difficult under dissolve fully under cold water condition at 5～10 ℃, and soup look clarification is bright not, easily there is macroscopic suspension.Instant black tea powder is modulated the acid icy bleak tea or the pure black tea of low sugar that form and is difficult to guarantee there is no suspension and precipitation within the shelf-life of regulation.Therefore, study the certainty that a kind of low-temperature instant black tea powder is present instant tea powder development.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind ofly can under the cold water condition of 5～10 ℃, dissolve fully, soup body clear, no suspended substance, without the preparation method of the instant black tea powder of precipitation.
Technical scheme provided by the invention is a kind of method of preparing instant black tea powder, comprises the following steps:
1) getting fresh tea passes withers, the object of withering is to make fresh leaf under certain conditions, appropriate moisture equably scatters and disappears, follow scattering and disappearing of moisture, cell liquid is concentrated, and cell leakage strengthens, the increased activity of enzyme, polyphenol oxidase and peroxidase activation, for sweat polyphenol compound enzymatic oxidation is laid a solid foundation; Withering time was advisable with 8～12 hours, and the moisture control of withering leaf is in 68% left and right.Preferably, described fresh tea passes is keemun or the Yunnan black tea of black tea class.
2) tea sealing after withering is placed on to freezing 24～36h at-30 ℃～-20 ℃; Tealeaves quick-frozen in the situation that moisture content is higher easily forms larger ice crystal, can make cell swell and break, and reaches broken wall.Preferably, described sealing is by the sealing of tealeaves PE bag.
3) tealeaves after freezing is rubbed and cut, the tea that obtains broken degree and be 0.30～0.40mm is broken; Rub to cut and make leaf cell structure dislocation and unicellular torsional deformation, thereby cause the fracture breakage of cell membrane, be conducive to the leaching of active ingredient.
4) utilize ultrasonic wave to the broken further impact grinding of tea, ultrasonic power is 23～30kHz, and duration of oscillation is 15～25min; Hyperacoustic mechanical oscillation will further be impacted cell, cause cell wall rupture, be conducive to the leaching of tealeaves inclusion.
5) broken at 25～30 ℃ of temperature, humidity 80%～90% condition bottom fermentation 30～50min to ultrasonic wave tea after treatment, obtain black tea;
6) by black tea extracting in water, filtration, get that filtrate is centrifugal, after suction filtration, micro-filtration, being concentrated into solid content is 20%～35%, dry, is instant black tea powder.The number of times of black tea extracting in water is 1～3 time, and the addition of each water is 3～20 times of black tea weight, and each extraction time is 10min～150min.After black tea extracts, utilize plate-frame filtering, filter tealeaf residue, filtrate is cooled to 10 ℃ of left and right, be placed in centrifuge centrifugal, be centrifugal 15～30min under 2500～3500r/min at rotating speed, suction filtration, then filter with the micropore filter element of 0.2～0.5 μ m, be concentrated into solid content 20%～35%, adopt vacuum freeze drying or spraying dry, obtain instant black tea powder.
Compared with prior art, the present invention has following beneficial effect:
1, the present invention adopts after freezing and rubs the method for cutting again ultrasonic impact, can effectively improve amino acid and thearubigin content in instant black tea powder, and reduce theabrownin content, and instant black tea powder flavour is obviously strengthened.
2, instant black tea powder of the present invention can under the cold water condition of 5～10 ℃, dissolve fully, soup body clear, no suspended substance, without precipitation, and tea aromatic strongly fragrant, mouthfeel is fragrant and sweet.
3, this technique is simple, easy to operate, is suitable for industrialized production.
