Description
Technical field
The invention belongs to mulberry leaf deep process technology field, particularly a kind of mulberry smears the preparation method of tea.
Background technology
Smear tea originate from China it is more early, but due to after the Ming Dynasty prevalence tealeaves bathing waste drink method, smear tea tea ceremony
Lost therewith, conventional tea mill also disappeares therewith.Nowadays, it as the recovery of Chinese tea culture develops, smears tea and is taken seriously again,
It is on the basis of smearing tea in ancient times that modern times, which smear tea, is adopted new technology, the natural steaming green tea ultrafine powder that new equipment is process,
Feature is:It is fragrance faint scent, simple and elegant, ultra tiny.The content of protein, amino acid and chlorophyll is very high;And tea polyphenols, caffeine
Content is relatively low, its additive-free, preservative free, prosthetic pigment can suspend in the hot water, not precipitate, bud green millet paste is presented,
Water is dissolved in as coffee, has taken into account the advantages of having tea and eating tea, is a kind of superfine product of green tea.At present, investigation is found at home
70% tea of smearing serves as food additives, and 20% smears tea applies for beverage production and tea ceremony, only a small amount of tea of smearing
Other industry.
The country set foot in mulberry smear tea technical research and development it is few, mulberry leaf, ancient times are described as " Radix Rhodiolae ", contain abundant ammonia
Base acid, Polyphenols, chromocor compound, good protein, polysaccharide, organic acid, alkaloid, vitamin, zinc, calcium, phosphorus, manganese, iron
Etc. various trace elements, be that health ministry confirms " integration of drinking and medicinal herbs " plant, be included in that " mankind 21 by international food health organization
Century one of ten big health food ", become the new food source of mankind's green;Highland tea is a kind of perennial wild woody plants, it comes
From in remote, thickly forested mountains, precipice woodland is grown on, by brook, in bushes, according to Li Shizhen (1518-1593 A.D.)《Compendium of Materia Medica》It records with prevention and controls
Treat hypertension, hyperlipidemia, beauty, profit throat and other effects.Contained with mulberry leaf with mulberry matcha powder made of the tea compatibility of highland beneficial to human body
Ingredient, even some aspects be better than matcha powder.
Invention content
In view of this, the purpose of the present invention is to provide the preparation methods that a kind of mulberry smears tea, carry out deep processing to mulberry leaf, obtain
Tea is smeared to the mulberry of smearing tea quality characteristic is met.
To achieve these goals, the present invention is achieved by the following scheme:
A kind of mulberry smears the preparation method of tea, includes the following steps:
(1) mulberry tree is transplanted:
To transplant mulberry tree in the preferable ginkgo woods of mountain area land occupation condition, the mulberry tree is the sterling kind through grafting or cuttage
Mulberry, and to its sun-shading after in spring, mulberry bud is sprouted, sunshade rate is 60~80%;
The sterling kind mulberry transplants standard, dense planting, per 667m with edible mulberry21000~1500 plants of plantation, tree-shaped are low dry
It forms, plant current year liftoff 20~30cm is done surely, and the spring in next year cuts down liftoff 30~40cm cut shoots and determines fist, so as to form what branch was grown thickly
Tree-shaped;
Based on ginkgo have preferable economic value, mountain area plant ginkgo it is more, for this purpose, adaptation to local conditions in silver
Mulberry tree is interplanted under apricot, using the shaded effects of ginkgo, is optionally assisted with sunshade net after the sprouting of spring mulberry bud, conducive to mulberry
The accumulation of the ingredients such as amino acid, chlorophyll in leaf improves the nutritional ingredient of mulberry leaf.
(2) mulberry leaf are picked:
Pick mulberry tree bud-leaf annual 4~May, while pick wild highland tea shoot leaf, remove petiole, and by mulberry tree bud-leaf and
Wild highland tea shoot leaf is by weight 7:3 are uniformly mixed, and tealeaves mixture are obtained, as preference, the mulberry tree bud-leaf and highland tea
Bud-leaf picks 1~2 leaf of a bud;
(3) boiling is handled:
Tealeaves mixture in step (2) is placed in boiling in the boiling treatment fluid boiled and handles 5~10s, the boiling
Treatment fluid is that the mixed liquor that the dietary alkali of its total weight 0.5~1% is prepared is added in pure water,
