preparation example Construction

[0024] A kind of preparation method of the dark tea beverage with α-amylase inhibitory activity, comprises the following steps:

[0025] After the black tea water extract is finely filtered through an ultra-microfiltration membrane or a microporous membrane, it is heated at 130-100°C for 15 minutes to more than 3 hours to obtain a black tea drink with α-amylase inhibitory activity. During the heating process, the heating temperature The lower the temperature, the longer the minimum heating time required. When the heating temperature is 130°C, the minimum heating time is 15 minutes, and when the heating temperature is 100°C, the minimum heating time is 3 hours.

[0026] The dark tea water extract can be the tea soup brewed by the conventional dark tea brewing method. Heating can significantly improve the inhibitory effect of black tea water extract on α-amylase hydrolysis of starch. The higher the heating temperature, the shorter the required heating time. When the heating te...

Embodiment 1

[0037] 400 grams of black tea, add 20 liters of water, heat to 95°C, keep warm for 60 minutes, and then filter to obtain a crude filtrate. After the crude filtrate is cooled, filter it with a microporous membrane with a pore size of 0.1-0.2 microns to obtain a fine filtrate. The fine filtrate is diluted with water to a tea-to-water ratio of 1:150 (every 150ml of tea water contains 1 gram of black tea), packed in a sealed can, placed in a high-pressure steam sterilizer, and heated at 130°C for 20 minutes to make a dark tea drink.

Embodiment 2

[0039] 400 grams of black tea, add 20 liters of water, heat to 95° C., keep warm for 60 minutes, and then filter to obtain a crude filtrate. After the crude filtrate is cooled, filter it with a microporous membrane with a pore size of 0.05-0.1 microns to obtain a fine filtrate. The fine filtrate is diluted with water to a tea-to-water ratio of 1:150 (every 150ml of tea water contains 1 gram of black tea), packed in a sealed can, placed in a high-pressure steam sterilizer, and heated at 130°C for 60 minutes to make a dark tea drink.

Abstract

The invention discloses a preparation method of a black tea beverage having alpha-amylase inhibition activity. The preparation method comprises: adding water to a black tea, carrying out heating extraction, filtering to obtain a dark tea water extraction liquid, carrying out fine filtration on the dark tea water extraction liquid by using an ultra-fine filtration membrane or micro-pore filtration membrane, and heating for more than 15 min-3 h at a temperature of 130-100 DEG C to obtain the black tea beverage having the alpha-amylase inhibition activity, wherein the lower the heating temperature during the heating process, the longer the required shortest heating time, the shortest heating time is 15 min when the heating temperature is 130 DEG C, and the heating is performed for at least 3 h when the heating temperature is 100 DEG C. According to the present invention, the dark tea water extraction liquid is subjected to the fine filtration and then the heating is performed to prepare the black tea beverage having the alpha-amylase inhibition activity; and the preparation method has characteristics of short step, convenient operation and easy achieving, and the prepared black tea beverage has the significant alpha-amylase inhibition activity.

Description

technical field [0001] The invention relates to the field of dark tea drinks, in particular to a dark tea drink with α-amylase inhibitory activity and a preparation method thereof. Background technique [0002] α-amylase inhibitor is a kind of α-glucosidase inhibitor, which is a relatively mature drug for treating diabetes and has been widely used in clinic. Its mechanism of action is: competitively inhibiting various α-glucosidases located in the small intestine, slowing down the decomposition of starch into glucose, thereby slowing down the absorption of glucose in the intestine and reducing postprandial hyperglycemia. α-glucosidase inhibitors do not stimulate β cells to secrete insulin, but can reduce postprandial insulin levels, indicating that they can increase insulin sensitivity. [0003] Clinical role of alpha-glucosidase inhibitors: [0004] (1) It can significantly reduce the risk of type 2 diabetes in patients with impaired glucose tolerance. Postprandial hyper...
