Abstract

The invention discloses a production technology of oolong rich in zinc and selenium. Excellent tea tree varieties and fresh leaf buds produced in Fenggang County, Guizhou Province serve as raw materials and are processed by strict work procedures. The technological process is as follows: picking up leaf buds, drying green, curing, withering, rocking, spreading, fixation, kneading, breaking up, wrapping-twisting, deblocking, slowing baking by soft fire, shaping and the like; after being refined by the above steps, the appearance of oolong is verdant and oleosus, tea shape is firm, aroma is strong and elegant after oolong is brewed and is constant, and liquor color is honey yellow and is gorgeous and bright. The oolong produced with the technology is mellow in taste and has obvious aftertaste, is rich in trace elements, such as zinc, selenium and the like as well as mineral substances and has peculiar nutrition healthcare value; zinc content is as high as 40-100 mg/ kg, and organic selenium content is 0.25-3.5 mg/kg.

Description

Be rich in zinc selenium production technology of oolong

Technical field

The present invention relates to a kind of processing technology of tealeaves, especially a kind of zinc selenium production technology of oolong that is rich in.

Background technology

Oolong tea is one of China's well-known tea, main product is in Anxi, Fujian, Guangdong, traditional manufacture craft is economized in Taiwan etc., its preparation method combines the advantage of green tea and black tea making, the red limit of greenery at the bottom of the realization tealeaves leaf, must be on the processing step through withering, shake green grass or young crops, fried green, operations such as oven dry, the product appearance of making is verdant, the hard knot of tea shape, open bubble back fragrant aroma, the soup look yellow is beautiful bright, flavour alcohol is refreshing, but the technology of traditional making oolong tea is not only complicated, and the very difficult uniformity that keeps quality, simultaneously owing to the dark brownish green raw material variety difference that is adopted, and processing technology is also variant.For the traditional handicraft with oolong tea is incorporated into zunyi, guizhou, natural conditions and variety characteristic according to the locality, both adopted the part technology of traditional tea making of oolong tea, reform part technology again and carried out the innovation of oolong tea processing technology, utilize the advantageous natural conditions in Guizhou, the tealeaves of being grown.Also create unique Guizhou Plateau the whole province unique be rich in zinc potassium and the Trinitarian natural nutrition health care of organic selenium zinc selenium oolong tea.

Summary of the invention

The purpose of this invention is to provide a kind of zinc selenium production technology of oolong that is rich in, the good tea tree breed and the bright leaf bud that adopt the Fenggang County, Guizhou Province to produce are raw material, through strict manufacturing procedure, its technological process is: pluck tender shoots, shine blue or green, cool blue or green, wither, shake green grass or young crops, stand blue or green, complete, knead, break up, rolling, deblock, operations such as the temperature fire is roasting slowly, setting refining, make its outward appearance verdant glossy, tea shape heavily fortified point knot, bubble back fragrant aroma gracefulness, sustained, soup look honey Huang, gorgeous bright.

The tealeaves that adopts local local tea variety to make processing in conjunction with this technology contains the content of the necessary trace element of human body and mineral matter, particularly organic zinc up to the 40-100 mg/kg.The content of organic selenium is the 0.25-3.5 mg/kg; be the ideal value of health food, zinc is the important component of plurality of enzymes in the human body, if human body lacks zinc; can cause and fertility, the quantity minimizing of growing relevant enzyme or active decline; cause hypoevolutism, feeblemindedness, fecundity reduces organic selenium; mainly the form with selenocysteine is present in the oxidizing ferment; participate in removing the free radical that human body metabolism produces, the hypofunction of protection human body cell delaying human body delays senility.

Description of drawings

Fig. 1 is a kind of process chart that is rich in zinc selenium production technology of oolong;

The specific embodiment

A kind of zinc selenium production technology of oolong that is rich in of the present invention, its specific embodiment contrast technological process block-diagram is further described:

Pluck the dark brownish green of local improved seeds tea tree;

1, wither dark brownish green, withering comprises and shines blue or green and cool blue or greenly, shines blue or green 60 minutes, and cool blue or green 30-60 minute, the activity time that withers was 90-120 minute, was about to dark brownish green indoor spreading for cooling of tedding the back in the cool place, and the stand is long-pending to be spread thickness and be no more than 10cm.Carry out in the air conditioning chamber, indoor temperature is controlled at 18-21 ℃.

2, shake green grass or young crops: in special container, shake and make dark brownish green mutual extrusion bump make the edge of tealeaves produce mechanical injuries, the enzymatic activity of the internal substance of damaged cell strengthens, improve the peat-reek and the alcoholic degree of its zinc selenium, shook blue or green 180 minutes, blue or green 90 minutes of stand, shaking blue or green alternately the repetition with stand green grass or young crops is rereeling, half fermentation of cool green grass or young crops, the old tender degree of optic lobe matter, and the degree water content of withering determines to shake the blue or green time.The process that the blue or green cool green grass or young crops in stand also is dark brownish green half fermentation in the normal temperature process just must complete for stopping fermentation.

3, complete: utilize microwave de-enzyming machine or traditional pot or roll stir-fry equipment and complete of completing, stop dark brownish green continuation fermentation, 190-200 ℃ of the temperature that completes, fixation time 5-30 minute, dark brownish green temperature rose to very soon at 90 ℃, completed to knead after finishing.

4, knead: 100-300 minute, the agglomerate that has kneaded is broken up 80 ℃ of following temperature bakings half-dried, to rub again after with solid cloth tea bag being wrapped up in, the rolling time is in 420 minutes.

5, bale breaking, multiple roasting 60 minutes slowly, setting, oven dry are finished product, wherein Hong Gan temperature is between 75-80 ℃.
