Abstract

The invention belongs to the technical field of food processing, and relates to a preparation method of bar-shaped brand-name high-quality green tea. The preparation method comprises the following steps: spreading, fixation, micro-wave auxiliary fixation, rolling, shaping, primary drying, frying, and far infrared fragrance increase. According to the preparation method of the bar-shaped brand-name and high-quality green tea, provided by the invention, the produced green tea is compact in shape and bar, has the jade-green color, is clear and refreshed in fragrance on the aspect of internal quality, has a tender chestnut flavor, mellow and cool taste, and yellow green and clear color, and is tender and uniform in infused leaves.

Description

The preparation method of bar shaped famous green tea

Technical field

The invention belongs to food processing technology field, relate to the preparation method of bar shaped famous green tea.

Background technology

Famous green tea in China's Tea Production and consumption in occupation of very important status.For 2013, whole nation Tea Production total amount is 189.01 ten thousand tons, the tealeaves output value 1106.24 hundred million yuan, and famous green tea output be 84.98 ten thousand tons, the output value reaches 755.01 hundred million yuan, proportion is respectively 44.96%, 68.25% of the whole nation, and visible famous green tea business efficiency is very outstanding.Sichuan is that Cha great province is produced in the whole nation, its good growing weather and geographical conditions are that good quality base established by tealeaves, green tea gains national fame as " river tea " characteristic brand for a long time, along with living standard raising and Tea Consumption are tending towards rationalization, high-quality, the famous green tea that characteristic and cost performance is high is more and more subject to the welcome in market, for Sichuan Province's Tea Production consumption in 2013, the whole province's tealeaves total amount 21.2 ten thousand tons, the tealeaves output value about 11,300,000,000 yuan, wherein famous green tea output about 11.5 ten thousand tons, the output value but reaches 87.2 hundred million yuan, the critical role of famous green tea in " river tea " market is seen some from this.So, develop a kind of novel, characteristic, product that cost performance is higher will for expanding the famous green tea market share, increase tealeaves synthesize quality and open up a new approach.

At present, in river, famous green tea is main mainly with bud shape tea, although simple bud tea exists the clear superiority of fragrance, flavour, not resistance to bubble, the shortcoming such as expensive are inevitable all the time.Bar shaped famous green tea is mainly with Mao Fengwei master, because it has certain maturity, component content is enriched, which avoid the feature of the not resistance to bubble of simple bud tea, in addition the price of material benefit relatively makes it deeply like by Tea Consumption person, but quality characteristic single for a long time allows the consumer pursuing novelty feel disappointed rather.Be necessary to launch research further and innovation, to producing the tea products more allowing consumer like for conventional strip famous green tea technique.

Summary of the invention

For above-mentioned technical problem, the invention provides a kind of processing method of bar shaped famous green tea, this processing method provides a kind of novel bar shaped famous green tea combination Titian technique, obtains the bar shaped famous green tea of a kind of comprehensive baking and fried green tea advantage.Concrete technical scheme is:

The preparation method of bar shaped famous green tea, comprises the following steps:

(1) pluck fresh leaf, fresh leaf is bud one, two leaf, is spread by fresh leaf and spreads on frame at multiple field, is placed in controlled temperature control and wets and between the stand green grass or young crops of ventilating good, spread to fresh leaf water content 68% ~ 70%;

(2) the stand leafiness spread is carried out roller fixation process, roller fixation temperature 200 DEG C ~ 250 DEG C, make water-removing leaves water content 60% ~ 65%, cooling moisture regain is carried out microwave benefit and is killed process to room temperature, microwave is mended and is killed temperature 80 DEG C ~ 90 DEG C, microwave de-enzyming leaf water content after mending and killing is 58% ~ 60%, and the water-removing leaves mended after killing carries out cooling processing immediately;

(3) water-removing leaves after cooling moisture regain is carried out kneading the type that does to process, knead to tealeaves rolled twig rate 95% ~ 98%; Knead overall 40min consuming time, comprising pneumatics 10min, gently press 10min, middle pressure 5min, pneumatics 5min, middle pressure 5min, pneumatics 5min;

(4) leaf of kneading obtained in step (3) is carried out block-separating and sifting, then enter dryer to carry out just drying process, first baking temperature 95 DEG C ~ 100 DEG C, just dries leaf water content 20% ~ 25%, enters immediately in sub-cooled storing machine and carries out cooling processing 1h after just drying by just drying leaf;

(5) the cooling leaf that step (4) processed is entered bottle stir-fry machine and carry out fried dry process, fried dry temperature 80 DEG C ~ 95 DEG C, to water content of tea 10% ~ 15%, fried dry leaf directly enters cooling storing machine and carries out cooling spreading for cooling process 1h;

(6) the cooling leaf that step (5) processed is entered the process of far infrared Titian, to water content of tea 5% ~ 6%.

The preparation method of bar shaped famous green tea provided by the invention, combination Titian technique, in conjunction with roller fixation, microwave benefit are killed, cool moisture regain, rolling shaping rapidly, just dried the techniques such as dry in earlier stage, produce the one-tenth that obtains to sample tea profile bar rope tight knot, the green profit of color and luster, endoplasm fragrance is invigorating, has tender Li Xiang, and flavour alcohol is felt well, soup look yellowish green is bright, tender even at the bottom of leaf.

Detailed description of the invention

Below in conjunction with specific embodiment, the present invention is further described:

Getting the fresh large white race two leaves and a bud in Fuding of harvesting just opens up as raw material, evenly spread after removal of impurities on multiple field frame for spreading fresh tea leaf, be placed on controlled temperature control wet and between the stand green grass or young crops of ventilating good, treat that fresh leaf spreads appropriateness, after fresh leaf water content 68% ~ 70%, carry out roller fixation process; Roller fixation temperature 240 DEG C, water-removing leaves water content 62% ~ 65%, cool moisture regain immediately, then carries out microwave benefit and kill process; Benefit kills temperature 80 DEG C, water-removing leaves water content about 58%, kneads process after cooling moisture regain; The equipment of kneading is 6CR-25 type kneading machine, kneads technique and is pneumatics 10min, gently presses 10min, middle pressure 5min, pneumatics 5min, middle pressure 5min, pneumatics 5min, leaf more than 95% rolled twig rate to be kneaded and slightly tea juice rub out and be advisable, then carry out block-separating and sifting; After screening, tealeaves enters and just dries operation, just dries temperature 100 DEG C, just dries leaf water content 20% ~ 22%, just dries leaf and carries out sub-cooled moisture regain process 1h immediately; The cooled leaf that just dries carries out fried dry process, fried dry temperature 80 DEG C, fried dry leaf water content 10% ~ 12%, after the process of sub-cooled moisture regain immediately 1h; Fried dry leaf after cooling is carried out the process of far infrared Titian, controls moisture content and be no more than 6%; Finally be cooled to room temperature, packaging, obtains bar shaped famous green tea finished product.

Sensory review is carried out to gained bar shaped famous green tea, the evaluation of organoleptic quality adopts method of weighting scores, tea ratio is 3g tea: 150mL, brewing time 5min, and specific procedure is: sample, coiling, commenting profile, sample, brew, go out soup, smell fragrance, see soup look, taste flavour, commenting at the bottom of leaf.Marked by 5 people, average.

Evaluate factor political trickery to be respectively: profile 30%, fragrance 25%, soup look 10%, flavour 25%, at the bottom of leaf 10%.Evaluation result is in table 1.

Table 1 is bar shaped famous green tea sensory review's term and sensory scores
