Description
Technical field：
The present invention relates to tea processing technical field, and in particular to a kind of preparation method of mulberry leaf yellow tea.
Background technology：
Mulberry leaf, ancient times are described as " Radix Rhodiolae ", contain abundant chromocor compound, good protein, polysaccharide, organic
The various trace elements such as acid, alkaloid, vitamin, amino acid, zinc, calcium, phosphorus, manganese, iron, it is that health ministry confirms that " medicine is eaten
It is homologous " plant, " one of ten big health food of mankind's 21 century " is included in by international food health organization, turns into the new food of mankind's green
Product source.
Traditional medicine thinks, mulberry leaf nature and flavor：It is sweet, flat, cold；With the clever ear that clears liver and improve vision, the function of calm nerve, to human body
Acted on dispelling wind and heat from the body, clearing away the lungheat and moisturizing, improving eyesight, cool blood etc..Especially in recent years by the generally acknowledged blood sugar reducing function in the external world, in mulberry leaf
There is a kind of glycosidase inhibitor, be 1-DNJ (DNJ), can be existed by the suppression to glycosidase so as to suppress disaccharide
The absorption of small intestine, reduce the peak value of postprandial blood sugar.The alkaloid and mulberry leaf polysaccharide contained in mulberry leaf, the β of pancreas islet can be promoted thin
Intracrine insulin.Insulin can promote utilization, hepatic glycogen synthesis and improvement glycometabolism of the cell to sugar, be finally reached reduction
The effect of blood glucose.
Wannan mountainous area is that tradition carries Sang Yangcan areas, and it is family's main economic source to breed silkworms sell cocoon over the years, in recent years due to
Being influenceed by overall situation, traditional sericulture is constantly in low state, and ruining mulberry, to lose one's parents phenomenon very universal, in order to change this state,
Agro-technician finds a way out from mulberry leaf comprehensive utilization, and Mulberry-leaf Tea processing and fabricating is exactly preferred.All imitating one after another in each sericulture area
Imitative to develop Mulberry-leaf Tea, folium mori black tea, mulberry leaf green tea, mulberry leaf oolong have production, but product bitter taste can not all purify.
This method goes out to send to make one kind from vexed yellow technique can reduce mulberry tea bitter taste, while addition is yellow in process
Essence, the health products of three kinds of ecosystems of propolis and Bee Pollen, the raw material of selection also have breakthrough.A few class mulberry tea presented hereinbefore, are adopted
It is all tender leaf and mulberry bud to pluck, because tender leaf fiber is few, moisture and the more easy-formations of pectin composition, still, mulberry after old leaf especially frost
Leaf generally acknowledges nutritional ingredient height by medical field, and bitter taste is also light compared with tender leaf.But old leaf moisture is few, it is not easy to make granular pattern
Tea, typically only do powder tea or do other medicinal material formulas.This technique is protected as far as possible by vexed yellow reduction moisture loss three times
Stay moisture few in old mulberry leaf, while increase the Bee Pollen of sealwort water, propolis and broken wall in process to moisturize
With mucus colloid, promote mulberry shaping.
The content of the invention：
The technical problems to be solved by the invention be to provide one kind realize mulberry leaf old leaf recycle, it is simple for process and
The preparation method of repeated strong, obvious health-care efficacy, special taste mulberry leaf yellow tea.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of preparation method of mulberry leaf yellow tea, it is characterised in that：Comprise the following steps that：
(1) mulberry leaf are plucked：Thick old leaf is plucked, white frontal lobe adopts 5-9 pieces, 3-6 pieces are adopted after frost, once purged to press the length of side
2cm is cut into positive square small pieces；
(2) mulberry leaf finish：Spray sealwort solution, is defined by squirting but not dripping, finished based on vexed kill before fixing, fixing temperature
At 260-280 DEG C, fixing appropriateness is rolled for mulberry leaf, has tentacle sense, sprays sealwort solution and propolis solution after fixing again for degree control
Mixed solution, fully mix thoroughly and close up heap；
(3) knead：With big kneading machine, routinely tea rolling method is light, weight, light principle are rubbed 40 minutes, and now sealwort is molten
Cement composition and the pectin in Mulberry-leaf Tea promote mulberry leaf to knead leaf into bar and shut down up to 60% one-tenth bar, then added in liquid and propolis
By the natural spp. pollen of broken wall, then rub barrel rotating speed is turned down, mulberry leaf can be made to turn in bucket turning in, gently rubbed, to kneading leaf
Vexed Huang, 35-40 DEG C of room temperature is kept, when agglomerating with tight tealeaves is held, loose one's grip and dissipate, so that it may go out leaf into type is made in next step, now
Mulberry leaf moisture content is 30-35%；
(4) type is made：By kneading the curling profile certain with vexed yellow mulberry leaf, it is put into frying pan and completes particle profile
Fragrance is improved with further.Fry yellow to tight knot ball-point pen type, greyish white frosting, Bai Zhongyin.
The compound method of sealwort solution is in the step (2)：Sealwort is first made 2000 mesh powders, then with 50 DEG C of temperature
Water is tuned into pasty state, then increases water and brews, and the weight ratio of sealwort and boiling water is 1:1, it is standby after natural cooling.
50% sealwort solution of spray before fixing, sprays 50% sealwort solution and 1% honeybee again in described step (2) after fixing
Sol solution mixed solution, water-removing leaves：Mixed solution=100:3, fully mix thoroughly and close up heap.
Described propolis solution compound method is：The weight of propolis and boiling water ratio is 1:100, it is standby after natural cooling.
Described boiling water is 70-75 DEG C of water.
The weight ratio that leaf and natural spp. pollen are kneaded in the step (3) is 50:1.
Frying pan, which increases by a pot body on original tealeaves song milli tea stir-frying pot and designs one, in the step (4) carries spilehole
Lid, play a part of vexed yellow tea leaf and development tea perfume, pot body is highly pot diameter 1/3rd, turns 0-60r/min, and elder generation exists
80-100 DEG C of pot temperature, quick tea frying 30min in the pot that 50 revs/min of rotating speed, after be adjusted to 40 DEG C -45 DEG C, 40 revs/min of rotating speed, make mulberry
Leaf low temperature vexed fried dry at a slow speed in pot, goes out tea, tea outlet is located at frying pan bottom, diameter 20cm for convenience.
Another processing method is not spray 50% sealwort solution and 1% after not spraying 50% sealwort solution, fixing before fixing
Propolis solution mixed solution, natural spp. pollen by broken wall is not added when kneading.
The details principle of making step of the present invention：
(1) spray sealwort solution before fixing, it is therefore an objective to moisturize and be easy to vexed kill；Sealwort solution is sprayed after fixing and adds propolis molten
Liquid, it is therefore an objective to which more crisp after mulberry leaf fixing, hydrojet eases back, and is advantageous to knead, while sealwort, propolis liquid have plurality kinds of health care work
With.
(2) sealwort, the propolis miscible fluid sprayed into when kneading in mulberry leaf contains lymphatic temperament, starch and sugar, can improve mulberry
The fragrant and sweet taste of leaf tea, and can cooperate with pectin contained in Mulberry-leaf Tea to promote mulberry leaf into bar.
(3) environment temperature is kept to reach 35-40 DEG C when gently rubbing vexed yellow, it is therefore an objective to make to knead leaf in certain damp and hot vexed yellow bar
Non- enzymatic oxidation is carried out under part, bitter material is decomposed in mulberry leaf, mulberry tea bitter taste is reduced, simultaneously because yellow semen, propolis
Make mulberry tea flavour fragrant and sweet mellow with the fragrant and sweet composition of Bee Pollen in itself, rolled when kneading leaf by long-time in rub barrel, it is damp and hot
Vexed yellow moisture simultaneously constantly scatters and disappears, most at last mulberry leaf water content control in 30-35%.
(4) thermal source of frying pan thermal current after bottom of pot body, heating is in floating state, and it is above than following temperature after measured
Spend high 5-10 DEG C, original frying pan belongs to open type, and heat is constantly lost in air, wastes the energy；And in dispersion process
In taken away a large amount of steam, have impact on mulberry tea shaping be also unfavorable for vexed Huang.So set up pot cover by increasing pot body height now
And the mode of small-sized air-vent is set on pot cover, prevent tealeaves steam largely to scatter and disappear and influence the vexed yellow and shaping of mulberry tea, simultaneously
The setting and can of small-sized air-vent promotes tealeaves slowly dehydration can not influence tea-leaf forming and fragrance development.
The innovative technology point of the present invention：
1st, vexed Huang：Whole technique is fully shown by vexed yellow destruction chlorophyll, theaflavin and thearubigin, promotes tea color
In golden yellow；Mulberry leaf are made to reduce bitter taste under certain moisture and certain temperature by vexed Huang, increase Mulberry-leaf Tea is sweet and pure and caramel
It is fragrant.The whole vexed Huang of technique has two kinds：One kind is damp and hot vexed Huang, and one kind is xeothermic vexed Huang, and damp and hot vexed Huang is to form yellow leaf yellow stuff, grow
The mellow main aspect of taste, xeothermic vexed Huang are the principal elements for developing Mulberry-leaf Tea fragrance.The vexed yellow technique of the present invention mainly has three times：
1) finish vexed Huang, and this is a kind of hot and humid vexed Huang.Increase mulberry leaf moisture by spraying sealwort solution, make inclined Lao Sang
Under certain moisture and hot conditions, chlorophyll is destroyed leaf, and Polyphenols oxidizing ferment, peroxidase lose activity, more
Phenolic compound issues in wet heat condition is born from dynamic oxidation and isomerization, and Starch Hydrolysis is monose, and protein is hydrolyzed to amino acid,
All to form the mellow flavour of mulberry leaf yellow tea and yellow creates conditions.
2) the vexed Huang of leaf low speed low temperature is kneaded, this is a kind of vexed Huang of high humidity low temperature.Leaf is kneaded by kneading, leaf cell is broken
It is bad, make mulberry leaf internal moisture fully exposed, then the low temperature vexed Huang at a slow speed in rub barrel, mulberry leaf are under high-moisture and under certain temperature
Hyther is carried out, it is damp and hot vexed yellow because moisture is high, change soon, it is damp and hot to cause a series of oxidations of composition, hydrolysis in leaf, this
It is the another main aspect to form mulberry leaf yellow stuff, flavour.
3) the xeothermic vexed Huang of frying pan, mulberry leaf make xeothermic vexed Huang under a small amount of moisture and certain temperature.This is that a kind of typical case is dry
The vexed Huang of heat, because moisture is few, change is slow, and under Temperature, ester catechin is cracked into simple catechin and gallic acid, increases
Add the mellow taste of yellow tea, in addition, under Temperature, sugar is converted into camerlsed, and amino acid is heated to be converted into volatile aldehydes
Material, this is the important composition for forming yellow tea fragrance.The part volatilization at a certain temperature of lower boiling aromatic substance, part are blue or green
Isomerization occurs for leaf-alcohol, switchs to delicate fragrance, higher boiling aromatic substance appears.
2nd, type is made：Old mulberry leaf are because moisture, pectin are few, and fiber is more, not easy-formation, and this technique is by increasing cement and water
Point, it is easy to shaping, reduces moisture evaporation additionally by vexed yellow technique, for mulberry leaf in special frying pan, mulberry leaf pass through stir-fry-hand in pot
Active force, extruding, ensures that limited moisture does not distribute in the presence of pot cover mutually, promotes the xeothermic vexed Huang of mulberry tea, control is necessarily
Temperature in frying pan into the particle profile of tight knot；Second, mulberry leaf under the continuous effect of stir-fry-hand, extrude mutually, until shaped like circle
Pearl, disc floret curling, tight knot is uniform, and the white frosting of color, Bai Zhongyin Huangs are off the pot, and brightness pot, mulberry leaf in pot are a variety of for a long time for mulberry tea
The mutual inversion of phases of composition, high boiling aromatic substance development is more, makes mulberry tea flavour is mellow, fragrance is dense to feel well；Third, mulberry leaf are by special
Different technique, mulberry tea appearance brightness is white, the bloom very thin just as having played layer, and the inside is golden yellow, just looks like eight or nine sun in morning, temperature
Without heat.There is very much ornamental value, liked by friend person in middle and old age very much.
3rd, the addition of Three natures circle natural health product：Increase sealwort solution, propolis by a certain percentage with environmental protection concept
And broker wall bee pollen, purpose one are that increase and is easy to make type Mulberry-leaf Tea mouthfeel, due to the partially old mulberry leaf of here, only by
Technique is not easy into ball-point pen type, and yellow semen, propolis have the saliva for having honeybee in cement constituents and Bee Pollen here, can fix mulberry leaf
Tea shapes, second, sealwort and Bee Pollen all contain higher natural amino acid composition, it is exactly to reduce phenol ammonia ratio to improve amino acid,
Just improve the quality of Mulberry-leaf Tea, especially Bee Pollen and integrate all sorts of flowers, flavour is fragrant and sweet, and the fragrance of flowers is strong.Third, these three days
Right health product, containing a variety of human body beneficials, the immunity of people can be improved.
Sealwort：The compositions such as the mucous matter of sealwort, starch, sugar, anthraquinone analog compound, several amino acids, vitamin.Pharmacology
Research has shown that sealwort can improve body's immunity, therefore strengthen human disease resistance.Sealwort also has antibacterial, hypoglycemic, decompression, anti-
Aging, the effect of beautiful appearance, strong energy.
Propolis：Propolis is the resin that honeybee gathers from plant gemma or trunk, is mixed into point of palatine gland, wax gland thereon
A kind of colloidal solid thing with aromatic odor that secretion is process.Propolis is a kind of extremely rare natural resources, is known as
The title of " purple gold ", include 20 major classes and more than totally 300 plant nutritional ingredient, wherein as many as flavone compound, its kind, content it
Height has exceeded in general autonomic drug.
Bee Pollen：Its main dietotherapy composition is:Protein, amino acid, vitamin, Bee Pollen element, trace element, activity
Enzyme, flavone compound, lipid, nucleic acid, brassin, phytic acid etc..Wherein amino acid content and ratio are closest to the United Nations's grain
The amino acid pattern that agriculture tissue (FAO) is recommended, this is extremely rare in wholefood.Bee Pollen is nutritious and drug effect valency

2nd, mulberry tea quality is improved
(1) vexed yellow technique, the vexed Huang of this technique have two kinds：Damp and hot vexed yellow and xeothermic vexed Huang.Damp and hot vexed Huang can improve mulberry tea
Flavour.Mulberry leaf carry out hyther under high-moisture and under certain temperature, and damp and hot vexed yellow because moisture is high, change is fast, Polyphenols
Compound issues in wet heat condition is born from dynamic oxidation and isomerization, and Starch Hydrolysis is monose, and protein is hydrolyzed to amino acid, all for
Form the mellow flavour of mulberry leaf yellow tea and yellow creates conditions；It is xeothermic vexed yellow favourable to development Mulberry-leaf Tea fragrance.Under Temperature,
Ester catechin is cracked into simple catechin and gallic acid, increase the mellow taste of yellow tea, in addition, under Temperature, sugar
Camerlsed is converted into, amino acid is heated to be converted into volatile aldehyde material, and this is the important composition for forming yellow tea fragrance.Low boiling
The part volatilization at a certain temperature of the aromatic substance of point, part leaf alcohol occur isomerization, switch to delicate fragrance, higher boiling aromatic substance
Matter appears.
(2) pot fries formative technology：By improving frying pan, increase frying pan lid, improve pot body height and set below pot
A tea outlet is counted, conveniently goes out tea, reduces revolutions per minute, that is, can guarantee that golden yellow color, profile tight knot particle, and can is protected
It is fragrant and sweet to demonstrate,prove mulberry tea mellow in taste, is easy to Rapid Popularization.First, leaf amount is thrown in increase, because there is lid, mulberry tea is not afraid of because measuring greatly one
Pot is run out of under fixed pendulum is dynamic, it is as far as possible to throw as long as tealeaves can turn in pot more, besides this technique final purpose mulberry tea turns yellow, mulberry tea
It is more, be more advantageous to vexed Huang, this is favourable to the color for forming mulberry leaf yellow tea；Two be due to that stir-fry plate amplitude is small, and rotating speed is slow, by
Slow in capping moisture loss, mulberry tea fried dry time in pot is grown, and increase tealeaves contacts with pot, can improve tea aroma energy simultaneously
Tealeaves is played bloom, make flavour mellow, fragrance is dense refreshing.Third, increase lid is exactly that preferably vexed Huang, tealeaves are xeothermic for tealeaves
Under effect, sugar is converted into camerlsed, and amino acid is heated to be converted into volatile aldehyde material, and this is the important of composition yellow tea fragrance
Composition.The part volatilization at a certain temperature of lower boiling aromatic substance, part leaf alcohol occurs isomerization, switchs to delicate fragrance, high
Boiling point aromatic substance appears.
(3) 3 kinds of natural health products are added.First, meet environmental protection condition, 3 kinds of health products contain a variety of human bodies beneficial into
Point, body immunity, three high drop can be improved, it is particularly possible to hypoglycemic, be adapted to friend person in middle and old age to drink for a long time；Second, profile is particle
