Method for producing green coffee bean extract

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...
