Abstract
The invention relates to a manufacturing method of instant yellow tea bags, and belongs to the field of food preparation. The manufacturing method comprises steps of withering, enzyme deactivation, decompression, heaping for yellowing, grinding, drying, and packaging. According to the invention, traditional tea leaf parching kettle is not used; pressure cookers are adopted for enzyme deactivation; and in the prior art, a kettle temperature about 180 DEG C can be achieved, and high temperature and pressure can be achieved in the manufacturing method, so that the structure of oxidase can be destroyed effectively, and enzyme deactivation time is shortened greatly.
Description
Technical field
The present invention relates to the preparation method that a kind of instant bag steeps yellow 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 yellow 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 yellow 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;
(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, being opened by the lid of pressure cooker rapidly, is atmospheric pressure by earth pressure release;
(4) vexed Huang: the lid lid of pressure cooker is returned, static 2 to 4 hours, or return to room temperature to it;
(5) grind: tealeaves is taken out from pressure cooker be ground to Powdered;
(6) 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;
(7) go-on-go, packaging: dried tea-leaf power carries out being distributed into bag.
Such scheme further improves and is: in described (7) 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 yellow 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, with raising efficiency with grinding technics.
Detailed description of the invention
embodiment
The instant bag of the present embodiment steeps the preparation method of yellow 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, being opened by the lid of pressure cooker rapidly, is atmospheric pressure by earth pressure release;
(4) vexed Huang: the lid lid of pressure cooker is returned, static 2 to 4 hours, or return to room temperature to it;
(5) grind: tealeaves is ground to Powdered;
(6) 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≤9.0% in powder;
(7) 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.
Of the present inventionly be not limited to above-described embodiment.All employings are equal to the technical scheme of replacing and being formed, and all drop on the protection domain of application claims.
