Abstract
A process for preparing the tea pigment includes such steps as mashing fresh tea leaves, adding enzyme, adding them to the solution of theopolyphenol in organic solvent, adding acidic aqueous solution, enzymatic oxidizing-polymerizing reaction, separating to obtain tea red, tea yellow and tea brown, purifying, concentrating and drying.
Description
(1) technical field
The present invention relates to utilize the tea extract to produce the method for tea pigment, be specially the enzyme that utilizes tealeaves itself and add or do not add the enzyme bought from the market method of oxidized teas polyphenol generation tea pigment together.
(2) background technology
Tea pigment is the mixture of Polyphenols and derivative thereof in the tealeaves, and its major ingredient is theoflavin class, thearubigins class, theabrownin class.Wherein theoflavin class pharmacologically active is the strongest, at present in the world the demanding criteria of tea pigment mainly a kind of high-active tawny agent and production method thereof have been announced be as the criterion .2001 February 28 Chinese Patent Office of the content requirement of theoflavin, in please number be 00112536, be characterized in directly Fresh Folium Camelliae sinensis being smashed to pieces slagging and leaf, add buffered soln then, add or do not add the tea extract tea-polyphenol, under ventilation and suitable temperature condition, carry out the enzymatic oxidn polyreaction, generate tea pigment based on theoflavin, thearubigins.Utilize this method, though the tea pigment of production wherein the content of theoflavin can reach 50%, the yield of tea pigment has only 50%, the theoflavin yield is lower like this.The reason that the yield of theoflavin is low is that the oxidizing reaction of this method is to carry out in the aqueous solution, and growing amount and the temperature of reaction of theoflavin in water has substantial connection, temperature is lower, theoflavin is not soluble in water, the theoflavin that generates during reaction is attached to the surface of enzyme, during solid-liquid separation, theoflavin is discharged from solid enzyme slag; And in the higher aqueous solution of temperature, though theoflavin is soluble in water, deep oxidation generates thearubigins and theabrownin rapidly under enzymatic reaction, has influenced the yield of theoflavin.
(3) summary of the invention
At the shortcoming that yield is lower and technology is loaded down with trivial details of theoflavin in the method for above-mentioned production tea pigment, the invention provides another production method of tea pigment, the yield height of theoflavin, process optimization, production cost is low.
Its main technical schemes is: a kind of method of producing tea pigment is characterized in that:
A, the processing of enzyme:
With the bright leaf of tea pulverize, rub cut, micronizing, standby under-16 ℃~-18 ℃ conditions;
B, enzymatic reaction: tea-polyphenol is added wiring solution-forming in the organic solvent, add acidic aqueous solution then, add the enzyme of a processing again, temperature is controlled between 10 ℃~65 ℃, stirs the reaction 0.5~5 hour of ventilating; Wherein: the weight of tea-polyphenol: volume of organic solvent=1 kilogram: 5~50 liters; Volume of organic solvent: the volume of acidic aqueous solution=1~10: 1; The weight of enzyme: the weight of tea-polyphenol=1~10: 1;
C separates: will go out water, slag phase, organic phase through the solution separating that b handles;
D, purifying: with the isolating organic phase of purifying agent abstraction purification c, it extracts than being the volume of organic phase: the volume of purifying agent=1: 0.5~3, collect organic phase;
E concentrates: place the scraper plate thickener to concentrate the organic phase behind the d purifying, organic solvent is removed on the top, and it is 5~25% to carry out spraying drying that water is made into solid content, and 60~65 ℃ of the temperature of scraper plate thickener, vacuum tightness are 0.06Mpa~0.08Mpa; 190~230 ℃ of the inlet temperature of spray-drying tower, air outlet temperature are 80~110 ℃, feed rate 50~500L/h.
Also the organic phase behind the purifying can be placed the scraper plate thickener to be concentrated into paste, place vacuum drying oven to dry to powder then, drying temperature is 45~60 ℃, and vacuum tightness is 0.06~0.08Mpa.Described acidic aqueous solution is that the pH value is 5~6.5 aqueous solutions of organic acids, for example aqueous citric acid solution or acetic acid aqueous solution
In the processing of enzyme, pulverize at the bright leaf of tea, rub and cut, can add polysaccharide hydrolase after the micronizing.Described organic solvent is a kind of in ethyl acetate, Virahol, ethanol, the chloroform at least.
The present invention utilizes the enzyme of the stronger tealeaves of activity itself, do not add or add the enzyme of buying from the market, impel polyphenolic compound oxypolymerization to generate the tea pigment that is rich in theoflavin, the yield of tea pigment can reach 80%, wherein the content of theoflavin reaches as high as more than 60%, advantage of the present invention is that the process of polyphenolic compound oxypolymerization generation tea pigment is carried out in multi phase state, the characteristics of this multi phase state enzymatic reaction are: 1, the reaction system temperature influence weakens, theoflavin has good solubility in organic solvent at low temperatures, and under comparatively high temps, owing to be reflected in the organic phase and carry out, reaction temperature and easy to control has suppressed the polyreaction of theoflavin continuation to thearubigins and theabrownin.2, thearubigins and theabrownin are not soluble in organic solvent, and the thearubigins of aqueous phase and the enrichment of theabrownin have also suppressed theoflavin and continued oxidation.More than 2 yield and both obvious raisings of purity that impelled theoflavin.So just avoided oxidizing reaction of the prior art to carry out in the aqueous solution, growing amount and the temperature of reaction of theoflavin in water has substantial connection, lower, the higher shortcoming that all can have influence on the yield of theoflavin of temperature.
