Abstract
A method for directly extracting theabrownin with pu'er tea serving as a raw material comprises the steps as follows: (1) putting the pu'er tea in a digestion container after crushing, injecting purified water for soaking, and combining extract liquor for use; (2) directly performing membrane filtration on the extract liquor after cooling to remove fiber impurities; (3) performing membrane concentration; (4) injecting an obtained lower-layer water into the container for an oxidative polymerization reaction; (5) performing vacuum concentration on a solution to obtain a concentrated solution with the concentration of 20-50%; (6) performing spray drying on the concentrated solution to obtain dry powder; (7) putting the obtained dry powder in supercritical CO2, removing micro-impurities and micro organic solvents; then drying the dry powder to enable the moisture content of the dry powder to be below 4% to obtain the solid theabrownin product. According to the method, the content of the theabrownin is increased, the production cost is reduced, the recovery rate is increased, and the problems that multiple organic solvents are used, the residue amount of the organic solvents is large and the like in the prior art are solved.
Description
Technical field
The invention belongs to field of deep tea processing technology, be specially a kind of method that Pu'er tea is raw material extracting directly theabrownin.
Background technology
Theabrownin piles in fermentation process holding of the black tea such as Pu'er tea, compound generation enzymatic based on fuer tea polyphenols and non-enzymatic reaction, through molecule amount heterogeneity, water miscible complicated natural high polymer that deep oxidation polymerization produces, it is the characteristic function quality component of black tea.Physiological effect effect of the black tea such as Pu'er tea and dark brownly have significant correlation.Theabrownin can effectively reduce blood fat, blood sugar and blood viscosity, in cardiovascular and cerebrovascular disease and diabetes mellitus prevention, have remarkable effect, can be used as the supplementary material of food and health products etc., has wide application prospect.The technology for producing of current theabrownin is little, mainly contain and take fermentation method for raw material with tea fresh leaves etc. or from the black tea such as Pu'er tea, adopt multiple organic solvent extraction and purifying, due to the complicated component of raw material, in the impurity of these methods in its preparation technology downstream and organic solvent removing, target product purification etc., technological process is loaded down with trivial details, energy consumption cost is high, environmental pollution is serious.
Summary of the invention
Technical problem solved by the invention is to provide a kind of efficient, the method that quick, low cost, high-recovery prepare theabrownin, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
Pu'er tea is a method for raw material extracting directly theabrownin, comprises the following steps:
(1) put into the molten device of lixiviate after Pu'er tea (ripe tea) being crushed to sheet, the pure water injecting 80 DEG C-90 DEG C soaks 40-60min, and be extracted liquid, the same terms repeats lixiviate once again, merges twice extract for subsequent use;
(2) after twice extract after merging being cooled to less than 40 DEG C, craspedodrome films are overanxious, removing fiber impurity;
(3) film is concentrated into the concentrate that concentration is 2-5%;
(4) lower aqueous layer obtained is injected in molten device carry out oxidative polymerization;
(5), after having reacted, be the concentrate of 20-50% by solution for vacuum concentration to concentration;
(6) concentrate is carried out spraying dry, obtained dry powder;
(7) gained dry powder is put into CO2 overcritical, remove trace impurity and minim organic solvent further, then dry further, make the moisture of dry powder below 4%, the theabrownin product of solid shape can be obtained.
In step (1), the Pu'er tea of input and the weight part ratio of water are 1:10, Pu'er tea invade circulating-heating in bubble process make liquid keep constant temperature.
In step (4), the time of described oxidative polymerization is 30-60min.
In step (6), the moisture of described dry powder is 10%.
In step (7), in described solid theabrownin, the content of theabrownin is more than 95%.
In sum, beneficial effect of the present invention:
Invention increases theabrownin content, reduce cost of manufacture, improve the rate of recovery, the problem such as overcome prior art with an organic solvent wide in variety, organic solvent residual is large.
Accompanying drawing explanation
Fig. 1 is present invention process flow chart.
