Embodiment 1

[0031] β-cyclodextrin-ellagic acid microspheres pomegranate leaf slimming black tea, prepared by the following method:

[0032] S1. Dissolve 100g of β-CD in 4000ml of distilled water to form a saturated aqueous solution, then slowly drop in the ethanol solution of ellagic acid prepared from 25g of pomegranate peel ellagic acid and 200ml of ethanol, stir at room temperature on a magnetic stirrer for 2 hours, and cool to Put it in the refrigerator overnight at room temperature, and then freeze-dry it with a desktop vacuum freeze dryer for 48 hours. The obtained spongy substance is pulverized into β-cyclodextrin-ellagic acid microspheres;

[0033] S2. Collect the young leaves on the new shoots of the pomegranate tree, spread them in the withering tank and wither, the thickness of the spread is 1.5cm, 25°C, 75% relative humidity, flip once every 2h, wither for 8h, until the leaf surface rises Wrinkles, leaf color dark green, knead the withered leaves, kneading temperature is 25 ℃,...

Embodiment 2

[0039] Sodium alginate-chitosan-ellagic acid microspheres pomegranate leaf slimming black tea, prepared by the following method:

[0040] S1. Pipette 200mL 0.1mol / L hydroxylamine hydrochloride solution into a dry and clean 2500mL beaker, add 800mL 0.5g / L sodium alginate solution and shake well, then add 2g ellagic acid powder, shake quickly and place in Heat in a constant temperature water bath at 50°C for 1 hour to obtain the product. The product is filtered through a microporous membrane to obtain a filtrate. Add 50g of chitosan to the filtrate as a sustained-release agent, stir with a magnetic stirrer for 1 hour to form a uniform and stable suspension, then add 50mL of 2% glutaraldehyde solution, freeze at -80°C for 2h, and vacuum at -50°C Dry for 12 hours to obtain a spongy complex, which is ground and pulverized to form sodium alginate-chitosan-ellagic acid microspheres;

[0041] S2, collect the young leaves on the new shoot of pomegranate tree;

[0042] S3, spread the...

Abstract

The invention discloses a preparation method of ellagic acid microsphere and pomegranate leaf weight-losing black tea. The preparation method comprises the following steps: preparing [beta]-cyclodextrin-ellagic acid microspheres or sodium alginate-chitosan-ellagic acid microspheres; collecting tender leaves on young pomegranate tree shoots, spreading the tender leaves in a withering trough for withering until leaf surfaces wrinkle and leaf color becomes dark green, rolling the withered leaves, spreading the withered leaves on a fermentation frame after the withered leaves are rolled to 90% or more into strips, performing fermentation under the conditions of wet cloth covering, 28 DEG C and relative humidity of 95% or more for 12 hours, then feeding the obtained fermented leaves into a drying machine, spreading the leaves with the thickness of 1.5 cm, performing drying at the temperature of 100 DEG C for 30 minutes, and naturally cooling; and uniformly mixing the dried pomegranate leaves with the ellagic acid microspheres according to a ratio of 50:1, and adsorbing the powder on the surfaces of the pomegranate leaves to obtain the ellagic acid microsphere and pomegranate leaf weight-losing black tea. The weight-losing effect of the obtained ellagic acid microsphere and pomegranate leaf weight-losing black tea is better than that of traditional pomegranate leaf black tea.

Description

technical field [0001] The invention belongs to the technical field of food engineering, and in particular relates to a preparation method of ellagic acid microspheres pomegranate leaf slimming black tea. Background technique [0002] Obesity is a chronic metabolic disease characterized by fat accumulation and weight gain, which often induces hyperlipidemia, diabetes, hypertension and other diseases. Slimming tea is a common weight-loss product on the market at present. Malt, lotus leaf, barley, oolong, Pu’er, hawthorn, chrysanthemum, dandelion, honey and other teas emerge in endlessly, but pomegranate slimming tea is still blank. As a functional component of pomegranate, ellagic acid has multiple functions such as weight loss, anti-tumor, hypoglycemic, and lipid-lowering; however, there are also problems such as difficult utilization of polymer pomegranate tannins, low free content, and instability. Therefore, exploring the development of a compound pomegranate leaf black ...
