A kind of Gingko white tea and preparation method thereof
Technical field
The invention belongs to the health beverages technical field, be specifically related to a kind of Gingko white tea, also relate to a kind of preparation method of Gingko white tea.
Technical background
The medicines and health protection of ginkgo leaf is worth and is disclosed by Chinese scholars, ginkgo leaf contains more than 20 kind of flavone compound, its content greater than 24%, mainly contains ginkgo diketone (Cinkgetin), Isoginkgetin (So ginkgetin), bilobetin (Bilobetin) in total extract.Also contain the terpene lactones compound in ginkgo leaf, diterpenoid-lactone mainly contains ginkgolides (Ginkgolide) A, B, C, M, J etc., and sesquiterpene lactone is Bilobalide (Bilobalide).In addition, also contain phenols, 25 kinds of beneficial elements, 17 seed amino acids, alkaloid etc.Modern study has the cardio and vascular function of improvement, relievings asthma, coronary artery dilating, resist myocardial ischemia, hemangiectasis, step-down, anti-platelet activating factor, inhibition platelet aggregation, delay senility, strengthen immunologic function, improve learning and memory function, anti-inflammatory, protect the liver, fall blood ester, the effect such as anticancer.Modern Application is used as the therapeutic agent of the diseases such as coronary heart disease, cerebral apoplexy, hyperlipidemia, diabetes, bronchial astehma, chronic bronchitis, and successful (Shen Yingjun waits the pharmacology of Chinese materia medica People's Health Publisher, and 2006,1040-1047).At present both at home and abroad medical science men's clinical trial proves, and ginkgo leaf health care tea is the new type of health tea of the treatment cerebrovascular and cardiovascular artery sclerosis, hypertension, diabetes, senile dementia.
Tealeaves; development along with science and technology; particularly since the seventies in last century; Japan and the United States and China have carried out a large amount of tealeaves to the research of the health care of human body; especially since the later stage eighties; multi-disciplinary intersection and infiltration make the health-care efficacy research of tealeaves enter a leap, obtain many breakthrough achievements, and are following the scale pattern of an ex vivo experiment-in vivo experiment-clinical trial-epidemiological study.these important achievement have: the inhibition (1975 of tealeaves to propagation of cancer cells, 1979), preventing decayed tooth (1981), antioxidation (1983), anti-platelet aggregation (1983), active anticancer (1984), hypotensive (1985), reducing blood lipid (1985), antiulcer (1987), suppress AIDS (HIV virus) (1990), antiallergy (1990), resisiting influenza virus (1990), clear and definite tealeaves is without carcinogenesis (1991), liver protecting (1992), improve intestine immunity (1992), anti-asthma (1990).
The chemical composition that exists in tealeaves, of a great variety, found kind more than 400, just human body is had obvious health-care effect.Can be divided into organic principle, comprise other joint compounds such as Tea Polyphenols, vitamin, amino acid, pigment and lipopolysaccharides, caffeine; Another kind of is the inorganic constituents of tealeaves, i.e. mineral element.Comprise the various trace elements of needed by human, all exist in tealeaves.Trace Elements in Tea has caused the attention of tea science man and even Medical scientists to the effect that health produces.
Tea Polyphenols is the compound with phenol chemical constitution that is present in tea, found kind more than 30, wherein catechin accounts for 70% left and right of Tea Polyphenols total amount, is not only one of main body of tealeaves green tea composition, and is the important component why tealeaves has health care.Tealeaves contained vitamin kind is quite a lot of, as human body day the replenishing of requirement, is more satisfactory, and particularly vitamin C and content of vitamin E are quite abundant, all have anti-ageing and oxidation resistant effect.
White tea belongs to slight fermented tea, is the special treasure in China's teas.Sample tea because of its one-tenth and mostly be the bud head, full slope pekoe is gained the name like snow as silver.The characteristics of white tea method for making are the activity of destructive enzyme neither, not accelerating oxidation effect again, and keep milli perfume (or spice) to manifest, soup is delicious refreshing.White tea, element is treasure in tea, and is with a long history, the appearance of its elegant name of a young woman, existing more than 880 years so far, Song Huizong (Zhao Ji) is in " grand sight tea opinion ", and have the white tea of joint monograph to say: " white tea is done for oneself a kind of, and is different from normal tea.It applies explains, and its leaf jade-like stone is thin, between the woods precipice, accidentally bears, though impersonal force can cause.The person of having, but four or five; Survivor, but one or two strains; Institute makes and terminates in two or three hips (Kua).Bud English is few, outstanding difficult steams roasting, and Tang Huoyi loses and become and be Chang Pin.Must make precise and tinyly, fortune degree is proper, in the table clear thorough as jade at uncut jade, its nothing and human relations are also.Shallow roasting also has it, but product are too late ".The white tea of " grand sight tea opinion " inner theorys is to originate in the imperial wild white tea that roasts on the tea hill in Beiyuan the phase, and is not identical with now white tea method for making.White tealeaves complexion pool is sea spray, and blade back spreads all over white fine hair; Fragrant milli is aobvious, delicious alcohol; The soup look apricot yellow is or orange limpid; Light gray at the bottom of leaf, vein is little red.Its property is refrigerant, detoxifcation is arranged, bring down a fever, fall effect of fire, is good drink in summer.
White tea, the nutritional labeling except having in green tea is characterized in that the free amine group content of Bai Chazhong is higher.The interferon secretory volume that can make the blood of human body immunocyte of having tea increases by 500, this is because the material of a kind of being called " theanine " is arranged in tealeaves, this theanine is decomposed into ethamine in the human liver, and the humoral immunity cell that ethamine can be transferred " gamma-delta T shape cell " by name promotes the secretion of interferon, and interferon to be human body resist infection " chemical defence line ", therefore can improve the ability that human body is resisted extraneous infringement.The content of common tealeaves Free Amino Acids only has 2%-4%, and wherein theanine accounts for the 50%-60% of total amino acid content.And white tea is a kind ofly to cause the chlorophyll disappearance and the genetic variant that produces by low temperature, is the Instinctive cultivar in tealeaves, and China various places all are found.Be that free aminoacid content in white tea of spring is general all more than 6%, high person even reaches 9%, the white tea of Anji County, Zhejiang Province for example, and its theanine content exceeds 1-2 doubly than general tealeaves, suffices to show that the various health-care efficacies that white tea has.
Ginkgo leaf and white a kind of trophism health protection tea of the composite composition of tea can make the elderly obtain health-care efficacy in drinking tea, and are the new type of health tea of the control cerebrovascular and cardiovascular artery sclerosis, hypertension, senile dementia; Having simultaneously detoxifcation, bring down a fever, fall effect of fire, is a kind of health protection tea of drinking suitable especially summer.
The health protection tea that single ginkgo leave tea of the prior art or ginkgo leaf and tealeaves assembly and ginkgo leaf and other useful raw material assembly things are prepared into, ubiquity has been ignored the effect of utilizing of effective component of ginkgo leaf, result causes its product weak effect, be difficult to reach the anticipation effect, thereby affected consumer's cognition degree, be difficult to promote.Trace it to its cause, the one, ginkgo leaf is due to growth period its cell membrane, the continuous lignifying of cell membrane, plucking time is different, its Texture Difference is very large, main component in ginkgo leaf is the organic principles such as bilobanone compound, lactone compound, poly-isoamyl alcohol and polysaccharides from ginkgo biloba that wherein contain besides, and after making tea, simple boiling water soaks, being difficult to its fat-soluble active ingredient is leached, is to cause drinking the undesirable main cause of rear effect.The 2nd, existing processing technology is unreasonable, is only simple method for preparing tea, is difficult to reach the medical curative effect of ginkgo leaf, can not realize the medical value of existing ginkgo leave tea.
Along with the problem of middle person year popular feeling cerebrovascular health more and more receives publicity, improve the value medical health care of ginkgo leaf, be combined with the good characteristic that white tea only has, should be able to bring into play effect better and address the above problem, particularly drink summer preferably, more have significant effect, but there is not yet relevant report in prior art.
