Embodiment 1

[0020] Pu’er tea is decocted and extracted 5 times with water at 100°C, the extraction time is 20 minutes, and the ratio of tea to water is 1:10; the extract is passed through a 20-mesh sieve, adsorbed by macroporous resin D101, and then eluted with 30% ethanol-water solution. The resulting effluent was concentrated under reduced pressure at 80°C to the ratio of tea leaves (weight):concentrate (volume) to 1:3.

[0021] The concentrated solution can be obtained by spray drying. The spray drying conditions are as follows: the inlet air temperature is 160°C, and the outlet air temperature is 80°C.

Embodiment 2

[0023] Pu’er tea is decocted and extracted 4 times with water at 80°C, the extraction time is 60 minutes, and the tea-to-water ratio is 1:8; the extract is passed through a 60-mesh sieve, absorbed by the macroporous resin NKA-9, and washed with 60% ethanol-water solution The resulting effluent was concentrated under reduced pressure at 75°C to tea leaves (weight): concentrated solution (volume) to a ratio of 1:5.

[0024] The concentrated solution can be obtained by freeze-drying. The freeze-drying temperature is -50°C, and the pressure is 0.1Mpa.

Embodiment 3

[0026] Pu’er tea is decocted and extracted 8 times with water at 90°C, the extraction time is 120 minutes, and the tea-to-water ratio is 1:3; the extract is passed through an 80-mesh sieve, adsorbed by macroporous resin NX-9, and washed with 90% ethanol-water solution The resulting effluent was concentrated under reduced pressure at 60°C to tea leaves (weight): concentrate (volume) = 1:2.

[0027] The concentrated solution can be obtained by spray drying. The spraying conditions are as follows: air inlet temperature: 140°C, and air outlet temperature: 70°C.

Abstract

The invention discloses a preparation method and an application of pu-erh tea extractive with a blood fat reducing function. The preparation method comprises the following steps in sequence of: adding water to the pu-erh tea to leach; filtering the extracting liquid; absorbing by macroporous resin; eluting by ethanol-water solution; concentrating the leaching liquid until reaching a certain proportion; and drying the concentrate, thus obtaining the pu-erh tea extractive. According to the preparation method, the characteristic of high effective component content of the pu-erh tea extractive is utilized to prepare the tea drinks, tea bags, pu-erh cream and tea beverage which have the effects of obviously controlling the raise of the weight, reducing the liver index, fat index and LEE'S index, raising high-density lipoprotein cholesterol and reducing triglyceride.

Description

technical field [0001] The invention discloses a preparation method and application of a Pu'er extract with the function of lowering blood fat. Background technique [0002] Hyperlipidemia is a systemic disease, refers to blood cholesterol (TC) and / or triglyceride (TG) is too high or high-density lipoprotein cholesterol (HDL-C) is too low, modern medicine is called dyslipidemia. Lipids are insoluble or slightly soluble in water and must be combined with proteins to exist in the form of lipoproteins. Therefore, hyperlipidemia is usually hyperlipoproteinemia. Currently recognized hyperlipidemia, including hypercholesterolemia (Hypercholesterolemia), hypertriglyceridemia (Hypertriglyceridemia) and complex hyperlipidemia. [0003] Hyperlipidemia can lead to liver function damage, long-term hyperlipidemia can lead to fatty liver, and hepatic atherosclerosis is damaged, and after liver lobules are damaged, the structure changes, and then leads to liver cirrhosis and damages liver...
