Description
Technical field
The present invention relates to a kind of production technology, particularly relate to the high-efficient production technology of a kind of tea polyphenols.
Background technology
Tea polyphenols is the general name of Polyphenols of Tea, including flavanol compound, anthocyanin class, flavonoid, flavonols
With phenolic acids etc., predominantly flavonol (catechin) class, catechin accounts for 60-80%, and class material tea polyphenols is also known as tea tan or tea list
Rather, it is one of Main Ingredients and Appearance forming Tea color fragrance, is also one of Main Ingredients and Appearance having health care in Folium Camelliae sinensis.Research table
Bright, the tool removing toxic substances of tea polyphenols isoreactivity material and radiation resistance, can effectively stop radioactive substance to invade bone marrow, and strontium can be made
90 and Co 60 excrete rapidly, be described as " radiation jinx " by healthy and medical circle.
Tea polyphenols is yellowish aqueous solution, powdery solid or the crystallization fragrant to dark brown slightly tea, tool astringent taste, soluble in water,
Ethanol, ethyl acetate, be slightly soluble in oils and fats, thermostability and acid resistance good, the most sufficiently stable in the range of pH2-7, slightly moisture absorption,
Aqueous solution pH3-4, the most oxidizable brown stain, meet iron ion and generate green black compounds.
Because the unique effects of tea polyphenols, medicine, health product and field of food the most it are widely used in.Pharmaceutically
As the protective agents of cardiovascular, liver, kidney and gastroenteropathy of human body；As improving human immunity on health product
The main component of the goods such as power, blood fat reducing, blood sugar lowering and fat-reducing, also main as sunscreen cream, shampoo and disinfection sanitizer
Composition；In fatty foods, add tea polyphenols, be possible to prevent food oyster to lose with fresh-keeping；The oxidation resistance of tea polyphenols is than VE, BHA
Strong with BHT 3-9 times, it is widely used as antioxidant and is used.
Tea polyphenols is green natural extract, in green 21 century great development potentiality.According to relevant professional person's introduction,
At present, the global consumption of tea polyphenols about 1600T, the wherein U.S. about 500T, Japan 400T, West Europe 400T, other area and states
Family about 300T.Since 2003, not only U.S.'s increase in demand is very fast, and the consumption such as Southeast Asia, South America rises the most year by year.Cause
The market of this current tea polyphenols the most constantly expands, and is in fast growth period, and gradually moves to maturity the phase.There is expert it is expected that not
Come several years, domestic and international tea polyphenols demand will rise more than 2000T from current 1600T rapidly, and its market scale is up to several
Hundred million yuan. the budding stage is still located in the tea polyphenols market of China, the most progressively replaces at field tea polyphenols such as beverage, cosmetics, health product
The chemical raw material originally used, application constantly expands.
The research and development of tea polyphenols, the eighties, enters and forms climax the nineties.In China, tea polyphenols in 1991 by
Academy of Agricultural Sciences of state institute technology first produces successfully, and annual output is only 2T, the production of tea polyphenols between more than 10 year thereafter
Technology has obtained quick development, and several processing technique are arisen at the historic moment, and meanwhile, is engaged in the pharmacology of tea polyphenols and application is ground in many
Study carefully under the joint efforts of expert, scholar, it has therefore proved that tea polyphenols prominent effect at aspects such as anticancer, antitumor, thus entirely
The development that tea polyphenols is applied has been promoted in the range of ball.At present, China is built and there are about three, 40 in the tea polyphenols factory total built
Family, but really there are only three, four of the market competitiveness (product quality, scale, cost and benefit).It main reason is that
Existing factory uses technique to fall behind, high cost, it is impossible to produce high standard tea polyphenols product.The production technology being currently mainly used
For the most several:
Solvent extraction, solvent extraction is to use reflux extraction by tea polyphenols from Folium Camelliae sinensis with hot water or ethanol solution
Leaching out, then carries out liquid-liquid extraction separation impurity by ethyl ester, finally concentrates and obtain product.Industrialized production at present
Tea polyphenols mainly uses this method.But owing to operation is different, the quality produced also has very big difference, approximately as: product is received
Rate is 5%～10%, and the purity of product is about 80%～98%, caffeine 4%～7%.
Ion catch electron microscopy, ion catch electron microscopy is to use reflux extraction by tea polyphenols from Folium Camelliae sinensis with hot water or ethanol solution
Leaching out, then utilizes metal to be centrifuged and becomes to precipitate at alkaline conditions and tea polyphenols complexation row, treat the caffeine in itself and solution,
After the Component seperation such as monosaccharide, aminoacid, dissolve under acidic condition, after concentrating by extraction, obtain tea polyphenols product.The method
Employing the heavy metal to human body is poisonous and make precipitant, its product is that food and medicine industry can not accept, additionally the method
Yield is low, and cost is high, and soda acid is big for environment pollution.The fluctuation of pH value easily causes greatly the Oxidative demage of polyphenols, makes into
Product color burn.
Column separating purification method, column separating purification method is to leach out by tea polyphenols from Folium Camelliae sinensis with hot water or ethanol solution,
Re-segmenting drip washing after post adsorbs, obtains tea polyphenols product after concentration.It has been reported that post separation preparation method have gel column, inhale
Attached column and ion exchange column.The most more focus on proposing highly purified research, more for this research separated with chromatographic column, technique
It is crucial that post inserts and drip washing research.Result show use post separation preparation method tea polyphenols yield between 4%-8%, pure
Degree up to 98.1%, as with gel column separate can height caffein-free, its residual quantity is only 0.1%.But post inserts such as absorption
Type resin, lipophilic gel etc. is much more expensive, and with multiple during drip washing, the production cycle is long, it is clear that to industrialized production tea polyphenols
It is inappropriate.Tea polyphenols product yield is low, cost is high in the method production, and easy resin material amount residual, impact is produced
Quality.
Above method produces tea polyphenols and there is yield low (less than 10%), relatively costly, and pollutes big, and quality controllability is poor
Etc. defect, and above method is all to use water to carry or ethanol solution high temperature extraction, and extraction process often uses reflux extraction,
Extraction solvent amount is big, and concentration time is long, and tea polyphenols is the most oxidized, and can produce substantial amounts of waste water, and wastewater problem does not has at all
Way is had to solve.On extracting method, additionally have also appeared excusing from death ripple extraction method, microwave loss mechanisms, super critical extraction, these
Although extracting method has certain advantage, but otherwise yield is little, otherwise extract the process in road after Process Impurity affects too much,
Otherwise be exactly that cost is the highest, so actually it is difficult to carry out large-scale production.
