CN102630772B - Method for promoting golden flower to grow on surface of black tea brick - Google Patents

Abstract

The invention relates to a method for promoting golden flowers to grow on the surface of a black tea brick, which comprises the steps: sheathing a black tea brick by airtight materials so as to control the peripheral microenvironment of the single black tea brick; and causing Eurotium cristatum to grow from the inside to the outside of the black tea brick so as to cause the golden flowers to evenly grow inside the black tea brick and on the surface of the black tea brick. Compared with the traditional black tea brick, the tea brick produced with the method disclosed by the invention has the advantages that the flowers grow uniformly inside and outside the tea brick, and the quality of the black tea brick is greatly enhanced. A precedent for the processing of the black tea brick is set with the method, thus consumers can directly understand the quality of the black tea brick, and quality testing staffs can also conveniently test the flower growing quality of the tea brick.

Description

A kind of method that promotes Fu brick tea brick superficial growth golden flower

Technical field

The present invention relates to processing field of tea leaves, be specially a kind of processing method of Fu brick tea.

Background technology

The Fu brick tea belongs to complete fermentation tea, it is the black tea product that in present all teas, processing technology is the most complicated, the production cycle is the longest, technique is unique, mainly sell to Tibet, Xinjiang, minority area, the borderland such as Gansu, Qinghai, the daily necessities of the regional ethnic group of NORTHWEST CHINA, have the saying of " would rather three days without food, can not a day without tea ".The Fu brick tea is with its unique health-care efficacy, is described as " tea of mystery, the tea of northwest various nationalities' life on Ancient Chinese Silk Road " by famous tea ceremony expert Mr. intelligence of Panasonic of Japan.The processing of tradition Fu brick tea is take Dark Green Tea as raw material, through screening, decatize, wet heap, suppress, grow dim and the operation such as dry processes, wherein fungus growing process is the critical process that forms the unique quality of Fu brick tea, its essence is by controlling certain temperature and humidity conditions and impel the coronoid process capsule bacterium growth and breeding in the Fu brick tea that falls apart, form flavous cleistothecium, be commonly called as " golden flower ".

Fu brick tea quality quality depends on the coronoid process upgrowth situation of capsule bacterium in the Fu brick tea that fall apart to a great extent, and the consumer is especially with this sole criterion of judging as Fu brick tea quality quality.Tradition Fu brick tea processing method makes the loose capsule bacterium of coronoid process only limit in Fu brick tea growth inside, can't be in the superficial growth of Fu brick tea brick, therefore just can observe the growing state of " golden flower " after consumer and quality inspection personnel often need to pry open brick tea, can't be from directly judging in appearance the quality of Fu brick tea, affected the consumer to the check to product of the judgement of product quality and quality inspection personnel.

Ouyang advises fragrant grade for (tealeaves communication, 1996, (2): 13-15), (Fujian tealeaves, 2009 such as Fang Hanhan, (1): 7-9), Li Jialian etc. (processing of farm products. academic periodical, 2011, (11): 48-52) all the control technique that grows dim of Fu brick tea has been carried out certain research, but all be confined to the regulation and control of growing dim of Fu brick tea inside, do not relate to the Fu brick tea brick surface control technique that grows dim.Technology is grown dim at present or blank out at home and abroad in Fu brick tea brick surface.

Summary of the invention

The problem of not growing dim for the Fu brick tea brick surface that thoroughly solves conventional method processing, make the effect of growing dim of Fu brick tea more directly perceived, the invention provides the method for the Fu of promotion brick tea brick superficial growth golden flower a kind of, the method all can be grown dim inside and outside not only making the Fu brick tea, and can make grow dim more luxuriant evenly.

Technical scheme of the present invention is: utilize the gas impermeable material cover to wrap up in brick tea and control monolithic Fu brick tea periphery microenvironment, make the loose capsule bacterium of coronoid process by growing to the brick outgrowth in brick, reach brick inner with the brick surface grow dim luxuriant evenly.

Operating procedure in technical solution of the present invention is specific as follows:

(1) gross tea decatize: the gross tea after pile-fermentation is the high temperature steaming certain hour in steaming the tea bucket, to reach the effect of sterilization and adjusting Measuring Moisture Content of Tea.

(2) build tea and become envelope: the gross tea after the decatize sterilization is built system in the envelope box that brown paper envelope box that whole wood pulp is made or other gas permeability are made than good material, makes the brick tea that builds up effectively and isolate from outer air.

(3) grow dim in brick: build the brick tea that makes and carry out brick inside grow dim in the drying room of controlling certain temperature and humidity conditions, and dried in the shade in the brick tea surface.

(4) grow dim in the brick surface: begin to occur the loose capsule bacterium mycelia of obvious coronoid process in brick tea after, wrap up in the tea envelope with the gas impermeable material cover of both ends open, two ends impel the loose capsule bacterium of coronoid process by growing to the brick outgrowth in brick with tampon or the material sealing preferably of other gas permeability.Brick tea after bagging continues to grow dim in drying room, after inner and brick surface all forms a large amount of flavous cleistotheciums until brick, can enter the alcoholization drying stage.

(5) alcoholization is dry: gradually the drying room temperature is risen to 40 ℃ by the speed of 2 ℃ of heating up every day, make the inner bone dry of brick tea, through packing vanning after the assay was approved.

Owing to adopting above technical scheme, the present invention compares with traditional Fu brick tea, all grow dim inside and outside brick tea luxuriant even, greatly promoted the quality of Fu brick tea, started the precedent of Fu brick tea processing, make the consumer can get more information about the quality of Fu brick tea, quality inspection personnel also can be checked the brick tea quality of growing dim more easily.

The specific embodiment

The invention will be further described below in conjunction with embodiment:

(1) gross tea decatize: after pile-fermentation gross tea to regulate water content be 24%, take 1300g gross tea and put into and steam the tea bucket, with high-temperature steam decatize 26 seconds, after decatize, moisture was 29%.

(2) build tea and become envelope: brown paper envelope box is placed in mould, first pours the gross tea after the decatize sterilization into dustpan, then fills with to advance to seal in box, builds while filling with, and guarantees that tealeaves compresses compacting.

(3) grow dim in brick: build the tea envelope that makes and send into drying room and grow dim, the drying room temperature is controlled at 24-29 ℃.

(4) grow dim in the brick surface: grew dim the 5th day, and wrapped up in the tea envelope with the air-locked material sleeve of both ends open, seal with tampon at two ends, and the tea envelope after bagging continues to grow dim in drying room, and the drying room temperature is controlled at 24-29 ℃, and this time of growing dim in stage is 10 days.

(5) alcoholization is dry: open the tea envelope and check the brick tea surface situation of growing dim, visible golden flower covers full brick tea surface, gradually the drying room temperature is risen to 40 ℃ by the speed of 2-3 ℃ of heating up every day, and be 5 days arid cycle, packing vanning after the assay was approved.
