Description
Technical field
The invention belongs to tea processing field, and in particular to a kind of Ramulus et Folium Mussaendae Pubescentis extract of high polyphenol content.
Background technology
Tealeaves, with the development of science and technology, especially since the seventies in last century, Japan and the United States and China have carried out largely
Since research of the tealeaves to the healthcare function of human body, especially the later stage eighties, multi-disciplinary intersection and infiltration make tealeaves
Health-care efficacy research enters a leap, obtains many breakthrough achievements, and follow an ex vivo experiment-in vivo
The scale pattern of experiment-clinical trial-epidemiological study.
Chemical composition present in tealeaves, type are various, it has been found that more than 400 kinds, just make with apparent health care to human body
With being segmented into organic principle, including other combinations such as tea polyphenols, vitamin, amino acid, pigment and lipopolysaccharides, caffeine
Object;Another kind of is the inorganic constituents of tealeaves, i.e. mineral element, including various trace elements needed by human, is all deposited in tealeaves
.The effect that Trace Elements in Tea generates health causes the attention of tea science man or even Medical scientists.
Tea polyphenols are the compounds with phenol chemical constitution for being present in tea, it has been found that have more than 30 kinds, wherein catechin
Account for about 70% or so of tea polyphenols total amount, be not only one of the main body of tealeaves green tea ingredient, and is why tealeaves has
There is the important component of healthcare function.Tealeaves contained vitamin type is quite a lot of, is more satisfactory as the supplement of human body day requirement
, especially vitamin C and content of vitamin E quite it is abundant, all there is anti-aging and oxidation resistant effect.
Free radical is the arch-criminal for threatening human health, and the catechu in tea polyphenols is known as the good work(for removing free radical
Effect, tea are big right plant products, are ideal health beverages.Further prove that tea is more according to clinic study in recent years
Catechin in phenol has anti-oxidant, radiation protection, lipid-loweringing, anticancer, anti-aging and other effects.
White tea belongs to slight fermented tea, is the special treasure in China's teas.Because its sample tea is mostly bud head, full slope pekoe,
As silver is gained the name like snow.The characteristics of white tea preparation method neither destructive enzyme activity, and do not promote oxidation, and keep milli fragrant aobvious
Existing, soup is delicious refreshing.Its property is refrigerant, have removing toxic substances, bring down a fever, fall fire the effect of, be summer good drink.White tea, except with the battalion in green tea
It forms point, its main feature is that the free amine group content in white tea is higher.Having tea can be such that the interferon of human blood immune cells secretes
Amount increases by 500, this is because there is the substance that one kind being called " theanine " in tealeaves, this theanine is decomposed into human liver
Ethamine, and ethamine can transfer the secretion of the humoral immunity cell promotion interferon of entitled " gamma-delta T shapes cell ", and
Interferon is that human body resists infection " chemical defence line ", therefore can improve the ability that human body resists extraneous infringement again.
With the quickening and variation of modern life rhythm, tradition " bubble drink " has been unable to meet multi-level consumption demand, in
It is that different-style and the fast and easily tea beverage of mouthfeel rich in functional component come into being.Although tea beverage currently on the market
Product is various, such as green tea beverage, ice black tea beverage, oolong tea beverage, jasmine tea beverage, but since white tea popularity is low
With white tea kind there are individual difference, if white tea soup look is shallow, tea perfume is light and slightly bitter, white tea beverage products pole in the market so far
It is few.
Although the technology of tea beverage processing in recent years makes much progress, many new and high technologies and equipment are answered
With, such as zymotechnic, membrane separation technique, microwave technology, aromatic substance recovery technology, freeze drying technology and aseptic filling technology.
However the research in terms of the domestic Ramulus et Folium Mussaendae Pubescentis extract to how to obtain high polyphenol content is still relatively fewer.
Invention content
In order to solve the above technical problems, the present invention provides a kind of Ramulus et Folium Mussaendae Pubescentis extracts of high polyphenol content.
The present invention is achieved by the following technical programs.
The present invention provides a kind of Ramulus et Folium Mussaendae Pubescentis extract of high polyphenol content, which is characterized in that the system of the Ramulus et Folium Mussaendae Pubescentis extract
Preparation Method includes the following steps:
(1) 10~30 mesh powders will be ground into after white tea tea-drying;
(2) the white tea leaf powders of 6~10g are weighed to be placed in 500ml conical flasks, 250~400mL distilled water is added at 75~95 DEG C
It is extracted in hot bath, isothermal vibration extracts 15~30min, repeats extraction 2~3 times, is filtered under diminished pressure while hot after extraction, filtrate
It is fitted into clean container and obtains white tea leaf powder Aqueous extracts, residue is washed with hot distilled water;
(3) the white tea leaf powder water that step (2) obtains is carried residue to be placed in 500ml conical flasks, it is dense that 250~400mL is added
For the ethanol solution that degree is 20~40% at 45~65 DEG C, isothermal vibration extracts 30~40min, is depressurized immediately after extraction
Filter, filtrate, which is fitted into clean container, obtains white tea leaf powder alcohol extract;
(4) the white tea leaf powder alcohol extracting residue that step (3) obtains is placed in 500ml conical flasks, is 1 by solid-liquid ratio:20
Ratio is added in deionized water, is added 0.1% acid protease and 0.02% pectase, adjust enzymolysis liquid pH to 5.0 into
Row extraction, extraction conditions are:Temperature 50 C, extraction time 60min, after enzymolysis enzyme deactivation live, be to extract through the filtering of 200 mesh
Liquid;
(5) extracting solution of above steps is merged, storage tank is sent into after screen filtration;
(6) ultrafiltration is carried out with the ultrafiltration membrane of 60000-80000 molecular weight, in 7.8-8.2MPa, normal temperature condition after ultrafiltration
Under, millet paste is concentrated into the concentrate of 25-35% containing solid content or more with reverse osmosis membrane;
(7) concentrate is sprayed dry under the conditions of 250-260 DEG C of spray dryer inlet temperature, 110-120 DEG C of outlet temperature
It is dry, Ramulus et Folium Mussaendae Pubescentis extract is made.
Further, the white tea tealeaves in the step (1) be selected from white peony, silver tip pekoe, tribute eyebrow, Shou Meizhong it is arbitrary
One or more combinations.
Further, the white tea tealeaves grinding particle size in the step (1) is 15~25 mesh, more preferably 20 mesh.
Further, the enzyme activity of the acid protease in the step (4) is ten thousand u/g of 1-1.5, and the enzyme activity of pectase is
3000-5000u/g。
The beneficial effects of the present invention are:
The present invention is by carrying water, alcohol extracting is combined with complex enzyme hydrolysis technology, can significantly improve white tea active ingredient
Recovery rate is carried compared to simple water, the recovery rate of alcohol extracting can improve 10% or so.Meanwhile the present invention uses acid protease knot
The dissolution of the active ingredient in white tea cell can preferably be promoted by closing the technology of pectinase enzymatic hydrolysis, compared to using single enzyme or
Person uses the combination of cellulase combining pectin enzyme, can improve recovery rate 3-5% of white tea active ingredient or so.Compared to existing
Technology, present invention obtains significant progress effect, also obtained in terms of the selection of compound enzyme unexpected research at
Fruit.
