A kind of health care compound tea manufacture craft
Affiliated technical field:
The invention belongs to the biofermentation field, related to a kind of health protection tea manufacture craft, more particularly related to a kind of process of utilizing sweet tea and Maoyanmei tea leaf to carry out the ferment making health protection tea.
Background technology
Sweet tea is the perennial rattan wood of the rose family, is the distinctive a kind of wild sweet taste plant in Guangxi, Dayao Mountain, main product Yu Wo district, and because its flavor is sweet, therefore named sweet tea.With Momordica grosvenori, STEVIA REBAUDIANA and claim Guangxi three large sweet taste plant, there is long applicating history China is among the people, local people are always when tea-drinking use for a long time, also are used for generation sugar processed food, also can be used as medicine.The chemical analysis analysis has been carried out with regard to sweet tea in analysis testing research center, Guangxi in 1979, determines that its chemical constitution that contains sweet substance is consistent with the rebaudioside, and sugariness is 300 times of sucrose, and calorific value is only 5% of sucrose.Through identifying, its sweet theine (sweet tea sugar glucoside) content is up to 6-7%.Through pharmacological testing, have hypoglycemic, hypotensive, the gastric acid inhibitory that enhances metabolism is too much, clearing heat and moistening lung, promotes the production of body fluid and quenches one's thirst and high sugariness is arranged, low-calorie characteristic, can make the auxiliary curing of diabetes, obesity.Hotness, heat being coughed and had curative effect preferably, have no side effect through toxicological test, is a kind of novel senior sweet taste health beverages in the world.It is tasty and refreshing that mouthfeel is fresh and sweet, all-ages.Often drink, can improve the health.
Both at home and abroad the aspects such as separation and Extraction, test and pharmacology of sweet theine is studied, the sweet theine that extracts on a small scale higher degree is also had to report, the Introduction To Cn Patent that publication number is CN102239983A a kind of method of extracting sweet theine from sweet tea, adopt the means such as column chromatography, crystallization and recrystallization to carry out preparing on a large scale sweet theine sterling, added as food additives, be widely used in the patients' such as obesity, hypertension, diabetes and heart disease health food.Detailed process is to adopt dry sweet tea later through with ethanolic solution extraction, filtration, reduced pressure concentration, then uses resin adsorption, ethanol elution, by the eluent reduced pressure concentration, decolouring, and crystallization and recrystallization make sweet theine sterling.Also contain a large amount of Tea Polyphenols with tealeaves is the same in sweet tea, also have Tea Polyphenols in documents and materials report sweet tea also to there is antibiotic, anti-oxidant and anti-aging effects.Due to sweet theine and Tea Polyphenols all very easily water-soluble, Tea Polyphenols is larger on the mouthfeel impact, what also be not suitable for suffering from indiestion is drunk by people, directly to brew drink tea fragrance not good for sweet tea in addition, if this Tea Polyphenols is processed and is converted into theaflavin isoreactivity material, can improve its mouthfeel, can make again its health care composition increase.
The Mao Yan certain kind of berries has another name called Tujia's sweet dew, the god of Tujia tea, Premna microphylla Turez etc.Its active ingredient is mainly dibydro myricetrin, flavones, contain 14 kinds of trace elements such as 17 seed amino acids of the needed by human such as leucine, isoleucine, methionine and potassium, calcium, iron, zinc, selenium simultaneously, wherein flavones highest detection content is 9.31%, be that in all plants of finding at present, flavones content is the highest, claimed " king of flavones " in plant.Mao Yan certain kind of berries main wild is in district rich in seleniums such as Zhangjiajies, and selenium content in Mao Yan certain kind of berries leaf is higher.The generation of selenium and diabetes, development close relation.Studies have found that, generally lack selenium in diabetic's body.Selenium has the effect similar to the insulin as hormone, and the direct sugar part in balance the body is conducive to the catabolism of sugar in diabetic's body part.
Flavones extensively is present in plant, is many medium-height grass the effective elements of the medicines, has sterilization anti-inflammatory, clearing heat and detoxicating, analgesia detumescence, blood fat-reducing blood pressure-decreasing, the cough-relieving that wets one's whistle, improves the function such as body immunity.Staphylococcus aureus, first, beta streptococcus, Diplococcus pneumopniae, Bacillus influenzae etc. are had to the very strong ability of killing, can discharge harmful sour phthalein and the ketoboidies of human body, eliminate the blood dirt in blood, regulate blood fat, blood pressure, softening blood vessel, adjusting renal function, strengthen the heavily absorption of renal tubule; Particularly treat the infection of the upper respiratory tract, acute/chronic pharyngitis, bronchitis successful.Flavones is fast the human body metabolism, do not accumulate, and human body self can not synthesize, so we need often to supplement.
Maoyanmei tea adopts this pure natural wild plant Mao Yan certain kind of berries exactly, adopt Tujia's tradition method for preparing tea to process in conjunction with the modern science tea-manufacturing technology is refining, in the Maoyanmei tea process, because unique processing method makes a large amount of dibydro myricetrin strippings in Mao Yan certain kind of berries blade, dibydro myricetrin crystallization under drying condition, white dot appears, shape is as mouldy, therefore also cry that mould tea, dibydro myricetrin make to have anti-inflammation and sterilization, reducing blood lipid, softening blood vessel, inhibition platelet aggregation, antithrombotic, antitumor, adjusting stomach, to the nervous system disease successful.
Golden flower is grown in being commonly called as of coronoid process in traditional Fu brick tea loose capsule bacterium (Eurotium Cristatum).This bacterium has the conversion that can promote various organic substances in tealeaves, greatly improves quality and the nutrition of fermented tea, makes tealeaves soup look reddish brown, and fragrance is pure, the characteristics that flavour is mellow.Modern study also shows that it has the effect that improves the blood of human body biochemical indicator and obviously deoil greasy, sharp digestion, lowering blood-fat and reducing weight.Thereby more and more cause people's attention.In order to promote growing dim of various tealeaves, many Tea Scientific Research personnel have carried out a large amount of research, for example: " Fu brick tea grow dim technical research " is on the books in 1996 " tealeaves communication ", the Fu brick tea optimum moisture content that grows dim is 20%-22% at high-temperature high humidity season, dry season is 22%-25%, while being greater than 30%, tealeaves goes mouldy, optimum thickness is 4-5cm, the best of brick is 30% containing the stalk amount, be difficult to grow dim lower than 5% the time, under the drying room temperature of growing dim conducting self-heating, with not higher than 25 ℃, under natural conditions, with 30 ℃, be advisable.The progress of dominant bacteria in process " the Fu brick tea grow dim " is also on the books in " the tea science technology " of 2005: the optimal temperature that the Fu brick tea grows dim is 28-30 ℃, the initial stage of growing dim is controlled at 25 ℃ of left and right, can bring up to 28-32 ℃ mid-term, and the pH value is 5, and humidity is below 70%.But can these researchs all rest on the Fu brick tea and grow dim.The Chinese patent that is CN102217688A at publication number describes in detail by the low temperature slowly fermenting and reduces tealeaves density and carry out large-scale production, with grow dim effect and improving the quality of products of change, can prevent from again to tealeaves is burnt core and goes mouldy simultaneously.But have limitation: a tea making mainly be take spring and summer season as main, and temperature is higher, and the various and easy growth of microbe species, adopt the low temperature slowly fermenting wayward, also not energy-conservation.Though reduce tealeaves density artificial and can not cause tealeaves burning core, how easy residual microorganism is more goes mouldy.Two present methods adopt the loose capsule bacterium liquid of the coronoid process of artificial culture or add tea juice, though strengthened the index of some aspect, can affect the original local flavor of whole fermented tea.Growing golden flower golden flower after long storage time on three tealeaves disappears.We take full advantage of tea making existence conditions in season, humidity and temperature is all higher, adopt hot and humid method, the artificial loose capsule bacterium spore of coronoid process that increases, reach the shortening fermentation period, through ultrasonic wave, golden flower is fixed again, thoroughly solve grow dim that monitoring is not in place, product burns core, go mouldy and long storage time after the problem such as golden flower disappearance, large-scale production goes out the traditional zymotic tea of original flavor, long shelf-life.
