Description
Technical field
The present invention relates to angelica keiskei tea preparing technical field, and in particular to a kind of preparation technology of marine alga angelica keiskei tea.
Background technology
Tealeaves and silk, porcelain are main product of the Ancient Times in China with world commerce, are enjoyed great prestige in the world.Tea is both a kind of text
Change, be a kind of leisure, the method for health again.
Angelica Keiskei, is Umbellales, celery section, angelica, the evergreen upright herbaceous plant of perennial root perennation.Because its growth is fast,
Vitality is strong, has " today priming leaf, tomorrow again long sprouting " phenomenon and gains the name.China name doctor Li Shizhen (1518-1593 A.D.) early in《Compendium of Materia Medica》
Angelica Keiskei is called into its " strand Radix Angelicae Sinensis " in (1593), its sweet, pungent, warm-natured, Return liver, the heart, large intestine channel is specified；In Japan's work
《Big and book on Chinese herbal medicine》(1709) and《Reformulate Compendium of Materia Medica initiation》Then there is Angelica Keiskei can strengthening body, health-care in (1844)
The effect of record, thus it is rare plant to be praised highly by people, is also that the Emperor Qin longevity god to be found is careless in legend.Tomorrow
Leaf present age research starts from 1960s Japan, introduces domestic in 1990s, has been introduced a fine variety at present to Hainan, Shandong
Etc. ground, recent year produced the publicity report of the food such as the health products such as angelica keiskei tea, capsule, medicine materical crude slice, and noodles, dessert
Road.Angelica Keiskei containing other plants such as the stronger chalcone of safety non-toxic, activity and organic germanium because do not have or content
Very low special nutrient compositions, so with special health-care effects such as hypoglycemic, liver protecting, anticancer, prevention cardiovascular and cerebrovascular diseases,
It is described as the healthy food of 21 century.
Angelica Keiskei when as tea history be difficult to it is fastidious.In Angelica Keiskei producing regions, existing open country such as eight zhang of islands of Japan
Raw, also have what resident planted, it is edible as daily vegetables.Until Japan medicinal herbs director of the Institute --- rattan after the doctor of medicine
Fast flag is in nineteen sixty-eight, in order to study Chinese prescription medicine, comes a hotel of having been put up for the night when Ba Zhangdao buys poisonous snake, has surprisingly had owner parent
Certainly the Angelica Keiskei cooking done, and the people on island is found because often eating Angelica Keiskei, it is not only very long-lived and all very healthy,
And Angelica Keiskei also has powerful vitality, so as to cause his curiosity to be studied.Pushed away by his 20 years of researches
Extensively, write as in 1999《Angelica Keiskei experience is talked》One book, Angelica Keiskei just walks out isolated island known to common people.At present, Angelica Keiskei
Product has 20% to be used for fresh vegetables supply, and 80% or so Angelica Keiskei has been processed to tea, powder, beverage, also serves as other foods
Product additive is used.
From documents and materials, the Angelica Keiskei that China is planted at present is all to be introduced from Japan for nearly 20 years.See earliest
Report is planting base to be gradually formed in Hainan Island from Japan's introduction in 2007, and has angelica keiskei tea product.Thereafter, tomorrow
Leaf also form planting base, wherein Shandong Angelica Keiskei bio tech ltd kind in coastal regions such as Shandong Rizhao, Qingdao
Plant scale has exceeded 230 mu.
As can be seen here, the formation of angelica keiskei tea commodity is the thing of nearly 20 years or so in the world, belongs to emerging integration of drinking and medicinal herbs
Drink.
Marine alga be marine algae plant blue-green algae, red algae, hidden algae, dinoflagellate, chrysophyceae, xanthophyta, diatom, brown alga, Euglena, green alga,
The general name of stonewort, has 11, up to ten thousand kinds.It is known that being available for the marine alga of human consumption has kind more than 70.Common marine alga has brown
Algae, red algae, green alga and blue-green algae, kind have sea-tangle, seaweed, agar, asparagus, undaria pinnitafida, sargassum fusifome, sargassum etc..
732.6 ten thousand tons of nineteen ninety-five whole world marine alga total output, 3,500,000 tons of China's marine alga yield accounts for 47.8%；Whole world marine alga in 2003
1083.4 ten thousand tons of total output, 721.6 ten thousand tons of China's marine alga yield, accounts for 66.6%.21 century is the century of ocean, marine resources
Development and utilization obtains the attention of world many countries, particularly developed country.China coastline is very long, marine site is vast, ocean
Aboundresources, attaches equal importance to marine resources development.For example, for as the representative sea-tangle of brown alga, being not only most important medicine food
Homologous sea-plant, and annual amount of regeneration is more than 15,000,000 tons.China's marine algae resource enrich, annual production up to more than 700 ten thousand tons,
Account for more than half of Gross World Product.Wherein, China's sea-tangle yield in 2015 reaches 1,320,000 tons, accounts for the 90% of Gross World Product
More than, there is huge resources advantage.But the utilization of sea-tangle is mainly at present and is directly used as food or extracts food addition
Agent, kind is also fewer, ten thousand yuan of ton valency 3-4, relatively cheap.How using sea-tangle resources advantage high value-added industries is converted into excellent
Gesture is one of the important goal of China in the blueness of startup in 2012 is economic.
Sea-tangle is not only a kind of nutritive value very high ocean vegetables, while also good medical value.For example, sea-tangle
Contain non-protein amino acid --- laminine, with decompression, reducing blood lipid, softening blood vessel, prevention cardiovascular and cerebrovascular disease effect；Sea
The taurine that band contains has protection eyesight, the effect of enhancing memory；Sea-tangle, which contains mannitol, diuresis, detumescence, shield kidney effect；
The algal polysaccharides that sea-tangle contains have active anticancer, hypoglycemic and improve immunity；The alginate tool chelating that sea-tangle contains
Toxin expelling effect of heavy metal ion etc..Other marine algas also have the medical value close with sea-tangle.In a word, including sea-tangle exists
Although interior marine alga nutritional ingredient is a lot, there is larger defect when being fabricated to tealeaves.One is to have bad smell is more difficult to remove,
Drink smell and mouthfeel all makes people uncomfortable, two water-soluble substanceses when being hot-water soak are few, especially algal polysaccharides molecule
Amount is big, it is difficult to dissolution, does not play nutrition health-care functions.

Sugar etc. is formed.For example, the patent of Application No. 201110178508.7 discloses a kind of preparation method of seaweed tea, and sea-tangle is ground
It is immersed in after powder in tea, adds monosodium glutamate, sugar, salt and cooking wine and form, it is difficult to keeps the outward appearance and local flavor of tea；Application No.
200610038915.3 patent discloses a kind of preparation method of seaweed tea, grinds and toasts after seawood meal and ginger powder are mixed,
Although ginger powder masks the bad smell of sea-tangle to a certain extent, fishy smell can not be removed completely, also can't resolve marine alga dissolution
The problem of thing is low, health-care effect is poor.The patent of Application No. 201510978649.5 discloses a kind of preparation method of seaweed tea,
Marine alga and asparagus, mulberry leaf, goat's horn piece, L-Borneol, almond, lotus leaf etc. are mixed and formed, the raw meat of marine alga is not only can't resolve
Smelly, poorly water-soluble problem, and without high-temperature process, easy moldy metamorphism；The patent of Application No. 20171027033.5 is disclosed
A kind of preparation method of seaweed tea, by four kinds of marine alga boiling dries pulverizings, then with remove raw meat liquid remove it is stench after pearl white mix
Conjunction is formed, complex process, time-consuming, external appearance characteristic and delicate fragrance characteristic without tea.

In above-mentioned technical proposal, retain 0.5-1cm petioles during harvesting Angelica Keiskei leaf, both facilitate harvesting, and blade is not
Broken, chalcone is not easily runed off in leaf, is conducive to kneading figuration, obtains uniform tea shape.
In above-mentioned technical proposal " frost opens seam " step, frost not only makes biological enzyme-deactivating in leaf, keeps chalcone etc. living
Property ingredient stability, and make the moisture freezing expansion in cell, train of thought, tissue becomes loose, is that bar is created in chalcone dissolution
Part.By it is demonstrated experimentally that by the angelica keiskei tea of frost, than the technique of direct tea making, chalcone dissolution rate improves 17-21%.
In above-mentioned technical proposal " ice leaching protects green " step, water temperature reduced the dissolution of chalcone, and energy below 16 DEG C, both
The small molecule dissolution such as oxalic acid of astringent taste will be produced, and blade tomorrow for freezing pore is poured into ice is opened in mountain spring water, be can ensure that
Chlorophyll will not be oxidized, and can keep natural green, have significant color of protecting to act on；And directly pour into Angelica Keiskei leaf originally
In water, leaf is aoxidized by disinfectants such as the chlorine in running water quickly, and green is changed into yellowish-brown, and chalcone is oxidized, and makes tea
Quality be greatly reduced.
In above-mentioned technical proposal " dehydration is fixed wet " step, when Angelica Keiskei leaf surfaces adsorb water≤2%, not drip, most
Easily allow enzyme agent uniformly to coat, enzyme agent is not lost in, enzyme agent can be allowed to play maximum efficiency.When absorption water>When 2%, easily in equipment
Interior generation hydrops, enzyme agent is lost in, and the enzyme agent of Angelica Keiskei leaf surfaces is uneven, concentration cannot be guaranteed, and ferment treatment effect is poor.
In above-mentioned technical proposal " spray enzyme open chain " step, complex enzyme agent can effectively open Angelica Keiskei leaf cladding chalcone
Pectin layer, partial destruction cell membrane, the pectin network open chain of point by chain of calcium ion, when being brewed with more than 85 DEG C water, Cha Er
Ketone, organic germanium, calcium activated and other nutritional ingredients can effectively increase stripping quantity.Wherein, by " frost opens seam " and " spray enzyme open
The angelica keiskei tea of chain ", the chalcone stripping quantity than direct tea making increases 2-3 times, is effectively utilized the chalcone resource of preciousness, shows
Write the health-care effect for adding chalcone.
It should be noted that in above-mentioned technical proposal, when angelica keiskei tea is brewed with water, the technical difficulty of chalcone dissolution
Even if being that water temperature reaches 100 DEG C, chalcone stripping quantity does not reach the 30% of actual content still.Reason is three aspects：(1)
Angelica Keiskei leaf surfaces are the pectin water-proof function layers containing wax, and it is chelated by calcium ion by pectic substance macromolecular chain and formed
Chalcone, organic germanium, calcium activated and other nutritional ingredients in netted overcoat, leaf are all coated wherein by it, its non-parent
It is aqueous so that chalcone dissolution rate is very low；(2) Angelica Keiskei leaf is mainly made up of pectin layer, cellulose, hemilignin, water etc.,
The cell liquid nutritional ingredient such as chalcone, chlorophyll is stored in the cell membrane constituted containing them, close structure, also causes Cha Er
The nutritional ingredient dissolution rate such as ketone is very low；(3) chalcone is a kind of derivative containing diphenylethlene ketone special construction, although benzene
Contain hydroxyl on ring, but molecular weight is larger, polarity is smaller, it is water-soluble poor.So, although Angelica Keiskei is looking into of having now been found that
Your ketone content highest natural medicine-food dual purpose plant, due to the restriction of above-mentioned three aspects, with the direct tea making of Angelica Keiskei leaf, effectively
Composition chalcone stripping quantity causes the waste of this precious resources, health-care effect effect not over the 30% of its actual content
It is not good.
For above-mentioned reason, the present invention be using " frost opens seam " technique in order to allow moisture freezing expansion in vascular bundle,
Blade construction is set to become loose, chalcone dissolution rate ratio improves 17-21% with the direct tea making of Angelica Keiskei leaf, it can reach
45% or so.Meanwhile, loose structure is also beneficial to the enzymatic hydrolysis reaction in lower step process.By " spray enzyme open chain " technique, enzyme
Agent optional water takes off part pectic substance and cellulose macromolecule chain, and the netted protective layer of blade is by partial destruction, it is easier to allow
Hydrone infiltrates blade cell and its chalcone molecule, and when water temperature is up to or over 85 DEG C, chalcone dissolution rate can reach
Or more than the 95% of actual content, efficiently utilize this valuable medicine resource.While another peculiar guarantor in Angelica Keiskei
Strong composition --- organic germanium, it is the same also like chalcone, dissolution rate is significantly improved, health-care effect is improved.
Further optimization, the hydrolysis of the netted overcoat of the pectin to be formed is chelated by calcium ion, and calcium ion dissolution rate is also obtained
To increase, this natural biological calcium from Angelica Keiskei is more beneficial for absorbing, and is conducive to calcium replenishing.
In above-mentioned technical proposal, what " inactivation " was directly brought has the technical effect that, relative to adding alkaline agent sodium carbonate, 80 DEG C of temperature raisings
Enzyme-deactivating traditional handicraft, 200-220 DEG C of cartridge type continuous high temperature inactivation technology, it is only necessary to which 7s, the time is ultrashort, does not have alkaline agent sodium carbonate
Pollution, also just eliminates washing process, it is to avoid the loss of chalcone.Meanwhile, " second high-temperature technology " also saves drying needs
Plenty of time and secondary pollution problem and ted the larger place problem of occupancy." second high-temperature technology " can also be prevented effectively from Jiao
Tea, paste tea, chalcone oxidation, be charred smell cause to drink caused by the uncomfortable drawback of mouthfeel.
In above-mentioned technical proposal, what " rolling and modeling ", " drying and shaping ", " parch Titian " were directly brought has the technical effect that,
Band intra vane is transferred to after rolling and modeling and rotates 130-140 DEG C of drying and shaping of baker.Further optimization, improves band intra vane
The temperature of baker is rotated to 155-160 DEG C, and the fragrance ingredient in Angelica Keiskei overflows in surface, forms Angelica Keiskei fragrance.
In above-mentioned technical proposal, " cooling ageing ", the unique technology effect of " secondary to bakee out perfume (or spice) " are, by atmosphere
Cooling, allows Angelica Keiskei to contact oxygen, moisture, fragrance component is soaked, spread, being condensed in blade, and unfolds blade.Again by rising
10 DEG C or so of temperature, to 165-170 DEG C, short time (2-3min) secondary high-temperature bakees frying, has both avoided in a stir-frying-technology
High temperature is burned, and burnt gas pierces the disadvantage of larynx when drinking, and the larger fragrance component baking of molecular weight is come out, and makes fragrance more enriching
It is strongly fragrant.Simultaneously of short duration high temperature it also avoid the change of structure under chalcone high temperature, keep the activity of chalcone.
It should be further stated that, in above-mentioned technical proposal, by " parch Titian ", " secondary to bakee out perfume (or spice) " technique
Afterwards, although overcome a high temperature and bakee the too high disadvantage for causing the burnt gas thorn larynx of angelica keiskei tea, drinking mouthfeel discomfort of frying temperature,
But still there is tealeaves and be heated in stove inequality, quality differs, and fragrance is irregular, the problem of do not imprison.In order to overcome this drawback, this
Invention adds " the big packaging of cooling ", " ageing is fragrant " 3-7 days process engineering, and this problem is solved well.
In above-mentioned technical proposal, the unique technology effect of " pure algae is expanded " is, by expanded marine alga, its medicinal ingredient,
In terms of algal polysaccharides, expanded marine alga significantly improves 2-3 times than common marine alga boiling water dissolution rate.Experimental result is referring to table 1, table 2.
Many Sugar water stripping quantities of the non-expansion marine alga of table 1 and expanded marine alga at different temperatures
The different expanded marine algas of table 2 and the algal polysaccharides boiling water stripping quantity of the different sample of expanded mode
The volatile small molecules such as amine, aldehyde, ketone, hydrocarbon, alcohol, acid of the marine alga because being less than 300 containing molecular weight, and have bad smell.
Washing, boiling, pickling, alkali cleaning, also odorous encapsulation method all can not effectively remove fishy odor, can also bring pollution and nutrition into
The loss divided.The unique technology effect of " pure algae is expanded " is, moment release of pressure after the swelling temperature and extruding higher than 130 DEG C, not only
Fish-stench can be effectively removed, and the burnt odor gas of pleasant can be produced.
The unique technology effect of " pure algae is expanded " is, expanded so that marine alga volume increases 20-50 times, and produces cellular
Loose structure, the increase of surface area, under hot water infiltration, the nutriment stripping quantity such as polysaccharide is significantly improved.
In above-mentioned technical proposal, the unique technology effect of " blending of tea algae " is, using expanded marine alga and Angelica Keiskei half
Finished product is blended, and had both avoided and has added the influence to marine alga this perfume, medicinal active ingredient in early stage process, and can pass through lower step process again
" secondary to bakee out perfume (or spice) ", 165-170 DEG C, the short time it is heated after, the burnt odor gas of marine alga puffed strip and the faint scent of Angelica Keiskei are spelled
Mixed, one integrated mass thoroughly eliminates marine alga fishy odor.Again by last " ageing is fragrant " process, algae, tea perfume gas is set slowly to grow
Moisten Angelica Keiskei, the fragrance of Angelica Keiskei is reached and preferably modifies centralizing function, the sensory feel such as mouthfeel and smell is more preferable.The opposing party
Face, marine alga passes through the high temperature of 165-170 DEG C of short time, has killed microorganism, has overcome the defect easily gone mouldy.In addition, marine alga contains
There are abundant polysaccharides, the polysaccharides sugariness of dissolution during Instant Drinks can correct the bitter taste of Angelica Keiskei chalcone, drink more pleased
Happy mood, it is favourable physically and mentally healthy.
