Embodiment 1

[0041] This embodiment provides a black tea extract and a preparation method thereof. The black tea extract of this embodiment contains 23.1% theaflavins, 46.5% catechins and 30.4% other black tea fermented substances (the main components include tea brownin, thearubigin, tannin, gallic acid).

[0042] The content of each component in the theaflavins is 6.9% for TF1, 11.1% for TF2A and TF2B, and 5.1% for TF3.

[0043]The content of each component in the catechin is 0.6% for C, 3.9% for EGC, 27.2% for EGCG and 8.0% for ECG.

[0044] The above percentages are the mass percentages of each substance in the black tea extract.

[0045] The black tea extract of the present embodiment is prepared by the following method:

[0046] Grind 100g of fresh tea leaves with a grinder and pass through an 80-mesh sieve; put 1000g of tea polyphenols into a fermenter, add crushed fresh tea leaves, mix well, ferment at 26°C for 6.5 hours, pass through every 15 minutes The content of each compone...

Embodiment 2

[0048] This embodiment provides a black tea extract and its preparation method. The components in the black tea extract in this embodiment are 35.7% theaflavins and 64.3% catechins.

[0049] The content of each component in the theaflavins is 10% for TF1, 17.1% for TF2A and TF2B, and 8.6% for TF3.

[0050] The content of each component in the catechin is 0.8% for C, 6.5% for EGC, 40.7% for EGCG and 16.3% for ECG.

[0051] The above percentages are the mass percentages of each substance in the black tea extract.

[0052] The black tea extract of the present embodiment is prepared by the following method:

[0053] Mix 100g of commercially available theaflavin 40, 276g of commercially available theaflavin 60 and 200g of tea polyphenols, monitor the content of each component in real time by HPLC until the theaflavin content reaches 35.7%, and stop the preparation.

Abstract

The invention discloses a black tea extract. The black tea extract comprises the following components in parts by mass of 20-30 parts of theaflavin and 40-50 parts of catechin. The theaflavin and thecatechin in the black tea extract can be extracted by conventional high-concentration tea polyphenols in the field, and can also be theaflavin or catechin sold in the market in the field. The black tea extract provided by the invention not only can effectively restrain fat absorption, achieves the purpose of reducing weight, but also cannot generate large side effects; and besides, the preparationmethod of the black tea extract is simple and feasible and has large market value.

Description

technical field [0001] The present invention relates to black tea extract and its preparation method. Background technique [0002] Obesity has been the focus of attention in recent years. With the rapid increase of obese population in the world, people's health has been greatly threatened. Obesity can cause many serious diseases, such as diabetes, fatty liver and cardiovascular disease. Since the last century, researchers have been continuously devoting themselves to the research and development of weight-loss drugs. The first batch of weight-loss drugs mainly act on people’s central nervous system. By suppressing people’s appetite and controlling their diet, they can achieve the effect of weight loss. Among them, the most popular One of the most popular drug ingredients is sibutramine. However, with the increase of users, more and more serious side effects have been observed clinically. This kind of nervous system inhibitors has gradually been listed as illegal drugs by v...
