Abstract

The invention discloses a preparation method of a Fu tea by taking Maojian as a raw material, which comprises the following steps: A)selecting material and humidifying; B) piling; C)performing primary drying; D)performing secondary humidification; E)fermenting and growing fungus; F)performing secondary drying; and G)aging. The method selects green, nontoxic and nuisance-free Maojian, so that introduction of harmful substance can be solved from source, and Fu tea quality can be ensured. While choosing material, the Maojian with tender shoot having length of 1-2cm and width of less than 1cm can be taken as the material, so that the quality is uniform and excellent, and the prepared Fu tea has higher taste. After fermentation is completed, product is aged, so that the product quality is rich and excellent. The method has no special restriction to local water quality, and is in favor of popularization of the Fu tea.

Description

A kind of take high-quality green tea as Fu tea of raw material and preparation method thereof

Technical field

The present invention relates to a kind of take high-quality green tea as the Fu tea of raw material, is specially a kind of preparation method of new Fu tea.

Background technology

China is the native place of tea, the production of tea and drink the history of several thousand, tea of a great variety, and its medical care effect also comes into one's own day by day, health maintenance effect also just confirm by modern medicine and obtain important breakthrough.The biological activities such as Tea Polyphenols, amino acid, catechin, purine base, tea polysaccharide, yellow cave class, Tea Saponin, organic acid, vitamin, mineral matter are rich in tea, these compositions, at mediator's internal metabolism, have aspect effects such as strengthening immunity function, delay senility.Drink tea and extend a series of tea culture, enjoying healthy while being in a cheerful frame of mind.

Fu tea is the black tea in the large tea system of contemporary Chinese Tea Science six, is uniquely to see the teas of biological spore by naked eyes in all tea, is that single coronoid process falls apart unique tea kind of capsule bacterium fermentation; Due to biological agent in its sweat, converting compounds in tea, the fall apart generation of the biological spore of capsule bacterium of association biology enzyme, coronoid process all makes Fu tea have the nutrition and health care composition different with other tea and function, and there is unique mouthfeel and product drink effect, the property of Fu tea is just receiving the concern of domestic scholars and vast tea fan.

Fu tea is also known as " lake tea ", " volt tea ", " mansion tea ", " good fortune tea ", originate from the Song dynasty (1068 Christian eras), mainly sell to China border areas, therefore also known as " border-sale tea ", " limit tea ", primarily of Jingyang, Shaanxi area produce, after be transplanted to Yiyang of Hunan province produce.

5. the technology that the preparation of tradition Fu tea must possess following condition 1. tea raw material (Dark Green Tea) the 2. weather 3. water 4. people from Jingyang in Jingyang in Jingyang in Hunan must produce the hot summer days.Above-mentioned condition shows that the requirement of traditional Fu tea to raw material and technological process is very harsh, now make Fu tea and also still adopt the old Dark Green Tea in Hunan (Hunan Dark Green Tea tealeaves after sootiness acidity on the weak side, applicable coronoid process falls apart capsule bacteria growing), the condition of water quality in Jingyang and the weather conditions in Jingyang, suffered condition restriction is still more, limits it and promotes and development.

Summary of the invention

The object of this invention is to provide a kind of take high-quality green tea as the Fu tea preparation method of raw material, it utilizes high-quality green tea to do raw material, under the condition of suitable temperature and humidity and oxygen-supplying amount, the coronoid process capsule bacterium that falls apart is grown, suppress other varied bacteria growing, final production goes out the Fu tea of the capsule bacterium spore that to fall apart with coronoid process simultaneously.The present invention realizes by the following method:

A. select materials and humidification: the present invention selects high-quality green tea to be raw material, after selection by winnowing, screening, adopt 2kg/cm ²steam humidification, makes high-quality green tea water content be 15% ~ 30%;

B. wet heap: by the wet heap while hot of the high-quality green tea after humidification, wet heap process makes heap temperature control be advisable at 35 ~ 65 DEG C, and 6 ~ 12 hours wet heap time was advisable, wet heap material endpoint pH 5.5 ~ 6.5 is advisable;

C. primary drying: tea raw material good for wet heap is put into drying shed, baking temperature 80 ~ 110 DEG C, drying terminates rear Temperature fall, for subsequent use;

D. secondary humidifying: by dried tea raw material, through 2kg/cm ²steam humidification, humidification periods is 5 ~ 30 seconds, makes tea feed moisture content reach 20 ~ 40%;

E. ferment, grow dim: the tealeaves that humidification is good be pressed into various shape tea cake or be in bulkly placed in sealed fermenting indoor, indoor humidity controls 60 ~ 90%, and fermentation temperature controls at 20 ~ 40 DEG C; About 5-10 days grows coronoid process and to fall apart capsule bacterium spore, 15-20 days spore full maturitys.

F. redrying: the tealeaves fermented carries out drying under 40 ~ 90 DEG C of conditions, to water content less than 10%;

G. ageing: dried tea product continue ageing 1 ~ 6 month under 20 ~ 40 DEG C of conditions, can be used as finished product and dispatch from the factory.

It is characterized in that:

1. select materials with natural, nuisanceless, do not use agricultural chemicals, not genetically modified high-quality high-quality green tea is raw material, selects the high-quality green tea being about 1-2cm to do raw material.

The present invention has following outstanding advantages and good effect:

1, on raw material, by select natural, nuisanceless, do not use agricultural chemicals, not genetically modified high-quality green tea is raw material, solves the introducing of harmful substance from source, effectively ensure that the quality of Fu tea.

Select the high-quality green tea being about 1-2cm to do raw material when 2, selecting materials, make material quality more evenly, high-quality, make the Fu tea taste that obtains higher.

3, after redrying terminates, select to carry out ageing to tealeaves, make the quality of product more mellow excellent.

4. this manufacture craft is all not particularly limited conditions such as region water quality, is more conducive to the popularization of this Fu tea preparation method.

Detailed description of the invention

Embodiment 1

Enforcement of the present invention is realized by following step:

6. ferment (growing dim): coronoid process capsule bacteria growing process of faling apart is commonly called as " growing dim ", it is the crux of zymotechnique, by the tealeaves cake of press of water content 25% or the indoor being placed in 26 DEG C in bulk, fermenting cellar must be airtight, holding chamber humidity 70%, make the coronoid process capsule bacterium that falls apart start growth, within about seven days, grow coronoid process and to fall apart capsule bacterium spore, 15 days spore full maturitys;

7. dry: the tealeaves of fermentation to be put in 45 DEG C of drying rooms, slowly dry, about experience drying in 10 days, water content less than 10%;

8. ageing: dried tealeaves is placed in the indoor ageings of 28 DEG C of ageings and can packs for three months and dispatch from the factory.

Embodiment 2

1. the wet heap pre fermentation of raw material: after high-quality green tea sorting being sieved, adopt 2kg/cm ²steam, decatize humidification 20 seconds, makes water content reach 45%, and wet heap is in a reservoir while hot, controls wet stack temperature 65 DEG C, and 5 hours wet heap time, endpoint pH is 6.4;

2. primary drying: the tealeaves that wet heap is good is put into drying room and carries out drying under 95 DEG C of conditions, to water content less than 10%;

3. secondary humidifying: by tealeaves 2kg/cm ²steam decatize humidification, humidification periods 10 seconds, water content reaches 26%;

4. ferment, grow dim: by tealeaves cake of press, be placed in fermenting cellar, control room humidity 80%, temperature 30 DEG C, fermentation time 10 days;

5. dry: the tealeaves fermented is placed in drying shed, in 60 DEG C of condition dryings, dry about 7 days, survey water content less than 10% in tea;

6. ageing: dried tealeaves is placed in the indoor ageing of ageing six months, can packs and dispatch from the factory.
