Abstract
The invention discloses an extraction method of tea polyphenol. The extraction method of the tea polyphenol comprises the following steps: grinding raw material (tea stems, sifting tea or tea dust) into 20-30 meshes powder, extracting by using distilled water with the temperature of 90 DEG C, wherein the ratio of tea to water is (1:13)-(1:15), separating the tea soup obtained after extraction by a separation membrane, extracting the tea soup by using ethyl acetate, aging the extract phase for 12 hours, carrying out vacuum concentration, dissolving the concentrated solution by using ethyl acetate, then cleaning, filtering, drying in a vacuum drying oven for 6-8 hours, thereby obtaining the tea polyphenol. The cost is lowered and the efficiency is improved.
Description
Technical field
The present invention relates to the extracting method of Tea Polyphenols, relate in particular to a kind of method of extracting Tea Polyphenols from tea stalk, sifting tea or tea dust.
Background technology
In tealeaves, extract Tea Polyphenols that purifying obtains and be a class and take the Polyphenols compound that catechin is main body, it is a kind of desirable antioxidant from natural food, it has anti-ageing, radioresistance, removing human free radical, reduces the pharmacological functions such as blood sugar, inhibition tumor cell, in daily-use chemical industry, food processing, medicine and other fields, has important application.The extracting method recovery rate of Tea Polyphenols in Tea is low both at home and abroad at present, and cost is also higher, to be improved.
Summary of the invention
Object of the present invention provides a kind of extracting method of Tea Polyphenols, solves one or more in above-mentioned prior art problem.
According to an aspect of the present invention, provide a kind of extracting method of Tea Polyphenols, its raw material is tea stalk, sifting tea or tea dust, comprises the following steps:
1. raw material is ground to 20-30 order, with the distilled water lixiviate 10-15min of 90 ℃, tea ratio is 1:13-1:15.
2. the millet paste of lixiviate, after minute film separation, is extracted with ethyl acetate.
3. Vacuum Concentration was as a child carried out in extraction phase ageing 12.
4. concentrate is used acetic acid ethyl dissolution again.
5. again after clean, filtration treatment, send into the dry 6-8h of vacuum drying chamber, obtain Tea Polyphenols.
The present invention, by extract Tea Polyphenols from tea stalk, sifting tea or tea dust, has reduced cost, has improved efficiency.
The specific embodiment
An extracting method for Tea Polyphenols, its raw material is tea stalk, sifting tea or tea dust, and raw material is ground to 25 orders, with the distilled water lixiviate 13min of 90 ℃, tea ratio is 1:14.The millet paste of lixiviate, after minute film separation, is extracted with ethyl acetate.Vacuum Concentration was as a child carried out in extraction phase ageing 12.Concentrate is used acetic acid ethyl dissolution again.After cleaning, filtration treatment, send into the dry 7h of vacuum drying chamber again, obtain Tea Polyphenols.
In sum, the present invention, by extract Tea Polyphenols from tea stalk, sifting tea or tea dust, has reduced cost, has improved efficiency.
The above is only one embodiment of the present invention; it should be pointed out that to those skilled in the art, without departing from the concept of the premise of the invention; can also make some similar distortion and improvement, within these also should be considered as protection scope of the present invention.
Claims (1)
