Description
Technical field
The invention belongs to agricultural byproducts processing fields, disclose a kind of preparation method of red stilbene leaf green tea.
Background technique
Red stilbene have improve immunity, anti-oxidant, anti-aging, liver protection, hypoglycemic, etc. various health care functions, be China tradition
Natural resources of Chinese medicinal materials, red stilbene leaf contains the nutritional ingredient and active constituent of its a large amount of similar root, such as: polysaccharide, polyphenol, saponin(e are more
Kind active component utility value with higher.Be conducive to root growth after the red appropriate picking leaves of stilbene, this product is with red stilbene leaf
Raw material is processed into red stilbene leaf green tea using conventional green tea stir-frying-technology and microwave production technology, has processing cost opposite
Lower, the features such as product is beautiful, quality is higher, palatability is stronger, this technology is practical, anticipates with certain practical advice
Justice is suitable for industrialization promotion, good market prospect.
Summary of the invention
The object of the present invention is to provide a kind of preparation methods of red stilbene leaf green tea, are processed into using the product that this technology produces
This is relatively low, product is beautiful, quality is higher, palatability is stronger, and this technology is practical, anticipates with certain practical advice
Justice is suitable for industrialization promotion, good market prospect；Technical solution of the present invention is as follows:
A. the picking of raw material leaf
Picking: fresh, pollution-free, non agricultural chemical residuum, no disease and pests harm, the tender leaf picking without visible droplet are selected；It selects: after picking
Undesirable blade and impurity are strictly picked out in time；Classification: according to blade always tender degree be divided into it is different etc.
Grade provides raw material for the product of post-production different stage；Temporarily the leaf of working process can be in 0-4 DEG C of preservation 24-96h；
B. airing
The timely airing of raw material leaf is stirred in time in clean smooth plane space or container, avoids accumulation heat production, and
Shi Tongfeng；Airing at least 4-6h, until blade softens, moisture is down to 70%-80%, spreads thickness requirement less than 5-8cm.Come
Leaf not as good as processing in next step can be stored temporarily in 0-4 DEG C of preservation 24-96h；
C. it finishes
Using high temperature enzyme activity and remove the herbaceous taste of raw material leaf, partial moisture, passive oxidation enzymatic activity, etc. step
B. the leaf handled, which is placed in the iron pan that temperature is 150-200 DEG C or so or quickly stirs in roller fixation machine, promotes moisture to steam
Hair, fixation time 3-5min；It can also place it in microwave de-enzyming equipment and finish, or be finished using microwave technology, control
Power is 500-800W, and throwing leaf thickness is 3-5cm；Time controls in 1-2min；
D. it rubs and moulding
It is rubbed after step c. treated leaf is cooling by the kneading in technique tea twisting machine of green tea or by hand, it can be according to need
Slabbing, strip, spherical is processed to its moulding, etc.；
E. it dries
Treated that tealeaves needs to remove moisture immediately by step d., in 60-80 DEG C of iron pan or roller tea frying machine stir-frying or
Person, in frequency 2450MHZ, 300-500W, throws dry 2-5min under the conditions of leaf thickness is 3-5cm using microwave dryer, until
Moisture is dried to 10% hereinafter, being cooled to room temperature；
F. shaping
In order to make tealeaves, appearance is more beautiful, it is also necessary to which further shaping can imitate green tea shaping according to the different shape of tealeaves
The shaping of technology utilization trimmer or artificial shaping；
G. Titian
It assigns tealeaves dense tea smell, also needs gently to stir-fry in 60-80 DEG C of iron pan after step f. treated tealeaves is cooling
Or the Titian 20-40min in perfuming machine for tea, tealeaves integrity degree is kept as far as possible, is avoided because temperature is excessively high or stir-frying is too late
When it is fried；
H. screening and classification
According to the limpid degree of the color of finished product, integrity degree, the millet paste grade that production sharing is different, different qualities are filtered out
Tealeaves；
I. packing and storage
Product after classification is divided in packaging bag or the container of different size and material, it is desirable that packaging material leakproofness is good
Well, free from extraneous odour, transparency are good；The tealeaves drunk not in time will refrigerate in refrigerator, and carry out seal operation, prevent other peculiar smell
Pollution.
Specific embodiment
Below in conjunction with example, the present invention is further illustrated:
