Embodiment Construction

[0032] Such as figure 1 Shown, tea polyphenol extraction process comprises the following steps:

[0033] Step 1: Pulverize the tea raw materials into uniform particles;

[0034] Step 2: Extract the uniform tea leaves in step 1 with low-temperature circulating ultrasonic wall-breaking composite solvent,

[0035] Extract the tea polyphenol solution containing the residue;

[0036] Step 3: Filtrating the tea polyphenol solution containing residue in step 2 to obtain filtrate and filter residue;

[0037] Step 4: The filtrate in the step 3 is adsorbed through the uniform pore resin to obtain the resin and the

[0038] waste liquid, and then the resin for absorbing tea polyphenols is eluted to obtain a tea polyphenol eluent;

[0039] Step 5: Concentrating the tea polyphenol eluate in Step 4 under reduced pressure to form a finished product.

[0040] The low-temperature circulating ultrasonic wall-breaking composite solvent extraction in the step 2 includes the following steps: ad...

Abstract

The invention provides a process for extracting tea polyphenol. The process comprises the following steps of: 1, crushing a tea raw material into uniform particles; 2, performing low-temperature circulation and ultrasonic wall-breaking on the uniform particles of tea in step 1, and extracting by using a compound solvent to obtain residue-containing tea polyphenol solution; 3, filtering the residue-containing tea polyphenol solution in step 2 to obtain filtrate and filter residue; 4, absorbing the filtrate in step 3 by using an isoporous resin to obtain a resin on which the tea polyphenol is absorbed and waste liquid, and eluting the resin on which the tea polyphenol is absorbed to obtain tea polyphenol eluent; and 5, concentrating the tea polyphenol eluent in step 4 under reduced pressure to form a finished product. The disadvantages of poor impurity removal effect, high loss of active ingredients and a solvent, high energy consumption, high pollution and the like in the conventional process can be overcome; the extraction rate is improved; the quality of a product is improved; and production cost is reduced.

Description

technical field [0001] The invention relates to a process for extracting tea polyphenols. Background technique [0002] Tea is the beverage that is second only to water and is widely consumed in the world. It has a history of four or five thousand years as a traditional health drink of the Chinese nation. For a long time, tea has played a very important role in the health of the Chinese nation and the prevention and treatment of diseases. Accepted by the majority of the people, drinking tea can prevent some diseases has also been confirmed by epidemiology. In the past, people believed that drinking tea is good for health because tea contains vitamins and some trace elements, but this view is not comprehensive. Recent studies have shown that the most beneficial substance in tea is tea polyphenols with strong antioxidant capacity. Modern medical research has found that tea polyphenols are a new type of natural antioxidant, which has anti-tumor, anti-aging, fat-removing and ...
