Background
China is a world-wide tea-producing nation, and Chinese people have more than five thousand years of history of drinking tea, and the drinking tea is beneficial to the common knowledge of health people. Tea pigment, theabrownin and catechin in the tea have various effects of reducing blood fat, blood sugar and blood pressure, resisting oxidation, tumors, radiation, aging, cardiovascular and cerebrovascular diseases and the like, and the medicinal value of the tea is continuously valued by people. At present, people can extract and separate theabrownin from tea leaves, and the preparation method specifically comprises the steps of tea leaf leaching, multi-stage filtration, air-entrapping oxidation, reverse osmosis concentration, thermal concentration and the like, and has the following disadvantages:
the whole production process has long flow, large equipment investment and low production efficiency, and has ten working procedures from raw material input to theabrownin product output; the content of active ingredients of the product is low, and is only about 60 percent; the quality of the produced theabrownin is influenced by the quality of the raw materials and is not stable enough; a large amount of tea leaves and waste water are produced in the production process, the environmental pollution is great, and the site selection of a factory is greatly limited; the production process is very extensive, can not meet the requirements of fine chemical production, and has poor economic benefit.
Secondly, due to the long production process flow, the problem of frequent product quality fluctuation caused by human or equipment control errors in the production process is increased.
And thirdly, the raw materials can be purchased only nearby, so that the source of the raw materials is limited, the price of the raw materials is difficult to reduce, and the raw materials are easily influenced by natural disasters.
Disclosure of Invention
The invention aims to provide a method for preparing theabrownin by using instant tea powder as a raw material, which has the advantage of strong controllability, can improve the production efficiency and the product quality, broadens the source channel of the raw material, reduces the raw material cost and improves the economic benefit.
The method for preparing theabrownin by using instant tea powder as a raw material comprises the following steps:
A. selecting instant tea powder with the tea polyphenol content reaching the preset content;
B. dissolving instant tea powder in water to obtain tea water solution;
C. adding biological enzyme into the tea water solution for oxidation reaction;
D. filtering and concentrating the tea water solution after the oxidation reaction to obtain a concentrated solution with a preset concentration;
E. drying the concentrated solution to prepare powder to obtain the finished theabrownin product.
Specifically, the biological enzyme in the step C is pectin biological enzyme, and the tea water solution can better perform oxidation reaction under the catalytic action of the pectin biological enzyme.
In the preparation method of theabrownin, the instant tea powder with stable tea polyphenol content is directly adopted as the raw material, so that the source of the raw material is not limited by regions any more, the raw material can be imported from southeast Asia and the like, the price of the raw material is favorably reduced, the content of the tea polyphenol in the instant tea powder is 3-9 times of that of common tea or Pu' er tea, and the tea polyphenol is a main substance for converting the tea polyphenol into the theabrownin, so that the product produced by using the instant tea powder as the raw material has high theabrownin content, excellent quality and stable and reliable quality. The preparation method of the invention has the advantages that the production process flow is greatly shortened, the production procedures of tea extraction, slag discharge, filtration, fine filtration, membrane concentration and the like in the traditional preparation method are omitted, the fixed asset investment of a production line is saved, the production process is changed from a rough type to a fine chemical production mode, the human or equipment control errors in the production process are reduced, the preparation process is more accurate and controllable through the control of production process parameters, the quality of the produced theabrownin is more stable, and the content of effective components can reach more than 99%.
