Embodiment 1

[0019] Embodiment 1: The production method of the green coffee bean extract adopts the following specific techniques.

[0020] (1) Weigh 100kg of green coffee bean raw material, humidify and keep the green coffee bean moisture to 18wt%, and use 0.1MPa steam in the softening pot to soften for 5 minutes; after softening, keep the temperature of the green coffee bean at 70°C and the moisture content at 10wt%. The flaked green coffee beans obtained by flaking have a thickness of 0.2mm and a powder degree of 9.3% (that is, green coffee beans with a particle size of less than 20 mesh account for 9.3% of the total weight of the flaked green coffee beans).

[0021] (2) Prepare a mixed solvent according to 6# solvent oil: 80vol% ethanol = 1:2 (volume), use the mixed solvent to extract flake green coffee beans, the ratio of solid to liquid is 1:5 (kg / l), at 45 Extracted 3 times at ℃, 1.5 hours each time, to obtain a mixed solvent extract, the extraction rate of active ingredients reache...

Embodiment 2

[0023] Embodiment 2: The production method of the green coffee bean extract adopts the following specific techniques.

[0024] (1) Weigh 500kg of green coffee bean raw material, humidify and keep the green coffee bean moisture to 20wt%, use 0.1MPa steam in the softening pot to soften for 4.5 minutes, keep the temperature of the bean at 72°C after softening, and pass through the roller flaker Rolled flakes, the thickness of flake green coffee beans is 0.25mm, and the powder degree is 7.5%.

[0025] (2) Mix 6# solvent oil and 80% ethanol at a volume ratio of 1:2 to prepare a solvent, use the mixed solvent to extract flake green coffee beans, the ratio of solid to liquid is 1:4, and extract three times at 45°C, Extract 1.5 hours each time to obtain a mixed solvent extract, and the extraction rate of the active ingredient reaches 99.7%; add water to the extract according to a ratio of 1:1, leave it to stand for layering, and separate to obtain an ethanol-water layer and a 6# solve...

Embodiment 3

[0027] Embodiment 3: The production method of the green coffee bean extract adopts the following specific techniques.

[0028] (1) Weigh 200kg of green coffee bean raw material, humidify and keep the green coffee bean moisture to 16wt%, and use 0.11MPa steam in the softening pot to soften for 5 minutes; after softening, keep the temperature of the green coffee bean at 68°C and the moisture content at 10.5wt% , using a pair-roll flaking machine for flaking; the thickness of the flaky green coffee beans obtained by flaking is 0.3mm, and the powder degree is 6.4%.

[0029] (2) Extract flake green coffee beans with a mixed solvent of 6# solvent oil and ethanol, the ratio of solid to liquid is 1:6 (kg / l), and extract at 47°C to obtain an extract; add water to the extract , standing to separate layers, and separated to obtain an ethanol-water layer and a 6# solvent oil layer.

[0030] (3) Filtrate the ethanol-water layer, concentrate at a vapor pressure of 0.08MPa, a gas phase temp...

Abstract

The invention discloses a method for producing a green coffee bean extract. The method comprises the following steps: softening a green coffee bean raw material, and tabletting to obtain flaky green coffee beans; extracting the flaky green coffee beans with mixed solvent of No.6 solvent oil and ethanol; separating the extract with water to obtain an ethanol-water layer and a No.6 solvent oil layer; filtering and concentrating the ethanol-water layer, removing solvent residues from the ethanol-water layer, and drying in vacuum to obtain the green coffee bean extract. According to the method, the green coffee beans are treated by adopting a softening and tabletting method, so that the flaky raw material with broken cells and extraction availability can be obtained, and impurities when the powdered raw material is extracted can be effectively reduced; separation by adding water can be realized by extraction of mixed solvent of No.6 solvent oil and ethanol, and the green coffee bean extract and green coffee bean oil products can be prepared in one step. The method has the characteristics of simple and effective extraction, convenience in separation, high production efficiency, small content of product impurities, industrial production availability, simple process, high content of product effective components and high yield.

Description

technical field [0001] The invention relates to a method for extracting effective plant components, in particular to a method for producing green coffee bean extract. Background technique [0002] Green coffee bean extract is derived from the seeds of Rubiaceae plants Coffea Arabica L., Coffea canephora Pierreex Froehn. and Coffea liberica Bul1.ex H1en. Its main components are chlorogenic acid and its homologues, which have the functions of lowering blood pressure, anti-tumor, nourishing the kidney, and anti-oxidation. It can also be used as health food to make health food sweet and delicious. In recent years, scientists in the United States have proved the weight loss effect of green coffee bean extracts, and this type of product is very popular in the United States, Europe, and Japan. [0003] At present, the production of green coffee bean extract mostly adopts organic solvent extraction after crushing green coffee beans, and then obtains the product through simple purif...
