Description
Technical field
The invention belongs to tealeaves preparation technical fields, and in particular to a kind of tea and preparation method thereof rich in amino acid.
Background technique
γ-aminobutyric acid (GABA) is a kind of active skull cap components, is distributed widely in animal and plant body.Plant such as beans
Belong to, all contain GABA in ginseng category, the seed of Chinese herbal medicine etc., rhizome and tissue fluid.In animal body, GABA exists only in neural group
In knitting, the content in mesencephalic tissue is organized in 0.1~0.6me/g.Immunological investigation shows that the highest region of its concentration is big
Black substance in brain.GABA is that inhibiting nerve important in mammalian central nervous system conveys substance, about 30% maincenter mind
Through synapses using GABA as mediator.It plays an important role in human brain cortex, hippocampus, thalamus, basal ganglion and cerebellum,
And there is adjustment effect to the multiple functions of body.When GABA lacks in human body, anxiety, uneasiness, tired, worried etc. can be generated
Mood.
After the prior art is by disposable prolonged anaerobic fermentation, water-removing processing is being carried out, it is available to contain GABA
Tea.But in the obtained tea containing GABA of prior art preparation, GABA content is very low, and itself has strong bored acid
Taste, the tealeaves bubbled out not only has bored tart flavour and tea taste is strange, leads to the approval for itself hardly resulting in consumer.
Summary of the invention
At least one of the present invention for GABA content of the existing technology in low, the bored strong problem of tart flavour, provides one
Kind is rich in the preparation method of amino acid tea, including：
S1. tealeaves to be processed is subjected to water-removing pre-treatment, obtains pretreatment tea.
S2. pretreatment tea obtained by step S1 is subjected to conversion water-removing processing, obtains conversion water-removing tea.
S3. conversion water-removing tea obtained by step S2 is post-processed to obtain described rich in amino acid tea.
Further, pre-treatment described in step S1 includes：Firstly, tealeaves to be processed is withered, withering time is：
15-30 minutes.It is then placed into indoor standing 6-12 hours, completes the pre-treatment operation.
Further, described wither carries out under blue light environment or sunshine condition.
Further, conversion water-removing described in step S2, which is handled, includes：(1) pretreatment tea is subjected to anaerobic fermentation, is sent out
Ferment tea.(2) fermented tea is subjected to aerobic water-removing processing.(3) circulation step (1) and (2) carry out 1-10 round, obtain the conversion
Finish tea.
Further, conversion water-removing described in step S2, which is handled, includes：(1) pretreatment tea is subjected to first time anaerobic fermentation,
Fermentation time is：2-6 hours, obtain first time fermented tea.(2) first time fermented tea is laid on sunning tool, carries out the
Primary sunning water-removing operation, sunning time are 0.5-2 hours, obtain the tea that once finishes.(3) the primary water-removing tea is carried out the
Secondary anaerobic fermentation, fermentation time are：2-6 hours, obtain second of fermented tea.(4) second of fermented tea is placed in leaf rotation dress
In setting, carries out shaking treating 0.3-1 hours, obtain secondary water-removing tea.(5) the secondary water-removing tea third time is carried out to detest
Aerobe fermentation fermentation time 1-3 hours, obtains third time fermented tea.(6) the third time fermented tea is placed in high-temperature fixation device
It is interior, water-removing processing is carried out, the conversion water-removing tea is obtained.
Further, the method for the anaerobic fermentation is：Pretreatment tea is placed in round first.It then will fermentation
It is vacuumized in container.It finally pours nitrogen and maintains the set fermentation time, complete the anaerobic fermentation operation.
Further, carry out the anaerobic fermentation operation when, will be evacuated in round first -0.03 to -
0.06MPa.Then the air pressure poured in nitrogen to round is increased to -0.01 to -0.03MPa, and maintains the air pressure to hair
Ferment operation is completed.It takes out the air pressure poured in air to round before fermented tea into round and reaches chamber pressure.
Further, it is post-processed described in step S3 and includes：Conversion water-removing tea is subjected to the processing that eases back first.Then it will ease back
Tea carry out rubbing processing.Finished product is made in the tea after rubbing later, is obtained described rich in amino acid tea.
Further, it is described rub after tea, knead agglomerating, and be sealed in vacuum packaging bag after easing back again,
It obtains described rich in amino acid tea.
In addition, the tea rich in amino acid is rich in using above-mentioned the present invention also provides a kind of tea rich in amino acid
The preparation method of amino acid tea is prepared.
One of the present invention has at least the following advantages：
1. preparation method of the present invention can largely convert GABA for the bran propylhomoserin in tealeaves, to make in resulting tealeaves
Rich in GABA.
2. preparation method of the present invention can will not make tea while promoting the bran propylhomoserin in tealeaves to be largely converted into GABA
Leaf generates bored tart flavour, and gained tealeaves it is soaked after will not generate peculiar smell.
Specific embodiment
