Abstract
The invention relates to a preparation method of instant dark tea bag and belongs to the technical field of food preparation. The preparation method comprises the following steps: withering, fixation, pressure-relieving, pile fermenting, grinding, drying, packaging and so on. According to the preparation method of the instant dark tea bag provided by the invention, the traditional tea frying pan is replaced by a pressure cooker to deactivate enzyme. Compared with the traditional technology in which the in-pan temperature is about 180 DEG C, the preparation method is capable of reaching higher temperature and pressure, so that the oxidase structure is more effectively destroyed and the enzyme-deactivating time is greatly shortened.
Description
Technical field
The present invention relates to the preparation method that a kind of instant bag steeps black tea, belong to the preparing technical field of food.
Background technology
Completing is one of most important operation in tea-manufacturing technology, completing is oxidase active by high temperature and the fresh leaf of passivation, suppress the enzymatic oxidation of the Tea Polyphenols in fresh leaf etc., evaporate fresh leaf portion of water, make tealeaves deliquescing, be convenient to knead shaping, foul smell, promotes the formation of good fragrance simultaneously.Existing de-enzyming process is instrument mainly with the pot that completes, and needs to stir-fry for a long time.Need the time longer, be unfavorable for industrialized large-scale production.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, proposes the preparation method that a kind of instant bag with efficient de-enzyming process steeps black tea.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of instant bag steeps the preparation method of black tea, comprises the following steps:
((1) withers: select fresh tealeaves, removes after impurity is cleaned and evenly spread 8 to 24 hours, to tealeaves weightlessness 20% to 30% in the environment of drying ventilation;
(2) completing: tealeaves is put into pressure cooker, slowly heat, is 220 DEG C to 240 DEG C to kettle temperature, and pot inner pressure, between 2.1MPa to 2.4MPa, maintains 120 seconds to 180 seconds;
(3) pressure release: after stopping heating, rapidly the lid of pressure cooker is opened, by earth pressure release to atmospheric pressure;
(4) wet heap: tealeaves is put into wet storehouse and stack and carry out fermentation 12 to 18 hours, tealeaves is stacked for length, width and height are the cube of 1 meter, and tealeaves is piled carry out trickle and burlap Mulching treatment; 30 DEG C to 45 DEG C are maintained the temperature at, humidity 80% to 90% in wet storehouse;
(5) dry: the tealeaves fermented is spread out and dries;
(6) grind: tealeaves is ground to Powdered;
(7) dry: collect the tea-leaf power after grinding, and put into vacuum freeze dryer, control temperature is between subzero 24 DEG C to subzero 36 DEG C, and vacuum is 110 × 10
-3mBar, is dried to moisture≤6.0% in powder;
(8) go-on-go, packaging: dried tea-leaf power carries out being distributed into bag.
Such scheme further improves and is: in described (8) step, is weighed by tea-leaf power in 12 grams to 15 grams loading non-woven bags and makes instant tea bag.
Such scheme further improves and is: described impurity is the tealeaves of hair, stone, metal object, ill worm.
Such scheme further improves and is: be packaged in paper package box by the instant tea of 10 bags or 10 integral multiples wrapped.
Instant bag provided by the invention steeps the preparation method of black tea, abandoning tradition tea stir-frying pot, adopts pressure cooker to complete, compared to the kettle temperature of about 180 DEG C of traditional handicraft, the present invention can reach higher temperature and pressure, and more efficiently destruction oxidizing ferment structure, shortens fixation time greatly.Meanwhile, in the moment of earth pressure release, steam volume instantaneous expansion, can effectively break tealeaves fibre structure, makes the tea bag of final finished when soaking, larger, easier by its soluble ingredient stripping with the contact area of water.Further, tradition is replaced to knead technique, further improving production efficiency with grinding technics.
Detailed description of the invention
Embodiment
The instant bag of the present embodiment steeps the preparation method of black tea, comprises the following steps:
(1) wither: select fresh tealeaves, remove after impurity is cleaned and evenly spread 8 to 24 hours, to tealeaves weightlessness 20% to 30% in the environment of drying ventilation; Impurity is wherein hair, stone, metal object, the tealeaves of ill worm, rotten tealeaves etc.;
(2) completing: tealeaves is put into pressure cooker, slowly heat, is 220 DEG C to 240 DEG C to kettle temperature, and pot inner pressure, between 2.1MPa to 2.4MPa, maintains 120 seconds to 180 seconds;
(3) pressure release: after stopping heating, rapidly the lid of pressure cooker is opened, by earth pressure release to atmospheric pressure;
(4) wet heap: tealeaves is put into wet storehouse and stack and carry out fermentation 12 to 18 hours, tealeaves is stacked for length, width and height are the cube of 1 meter, and tealeaves is piled carry out trickle and burlap Mulching treatment; 30 DEG C to 45 DEG C are maintained the temperature at, humidity 80% to 90% in wet storehouse;
(5) dry: the tealeaves fermented is spread out and dries;
(6) grind: tealeaves is ground to Powdered;
(7) dry: collect the tea-leaf power after grinding, and put into vacuum freeze dryer, control temperature is between subzero 24 DEG C to subzero 36 DEG C, and vacuum is 110 × 10
-3mBar, is dried to moisture≤6.0% in powder;
(8) go-on-go, packaging: tea-leaf power is weighed in 12 grams to 15 grams loading non-woven bags and make instant tea bag; Again according to customer demand, instant tea bag is loaded in paper package box with the multiple of 10 bags or 10 bags.
