Problems solved by technology

The notification number CN101133015B discloses a manufacturing method of a chlorogenic acid composition, which uses hot water to extract chlorogenic acid from coffee beans, and then directly decaffeines the macroporous adsorption resin; the disadvantage of this process is that the chlorogenic acid is sensitive to heat, Difficult to extract at high temperature, and direct resin treatment, the product has poor clarity in water and low effective content of chlorogenic acid; Omozoje Ohiokpehai research believes that high temperature will cause isomerization of CQA\FQA, which changes the isomerization of chlorogenic acid in coffee beans body ratio, which cannot meet the application of coffee bean chlorogenic acid in medicine and health care products

Abstract

The invention discloses a method for extracting a chlorogenic acid composition and coffee bean oil from coffee beans. The method comprises the steps: (1) crushing or tabletting green coffee beans or baked coffee beans, and then extracting by using butane or petroleum ether to obtain the coffee bean oil; (2) extracting chlorogenic acid by using an organic solvent from the raw material after oil extraction; (3) concentrating a chlorogenic acid extracting solution to be solvent-free, diluting by using water, and then filtering to remove impurities by adopting a ceramic membrane; and (4) removing caffeine from filtrate directly through macroporous adsorption resin, and carrying out nanofiltration and concentration on a desorption solution to obtain a concentrated solution of the chlorogenic acid composition. According to the method disclosed by the invention, the coffee bean oil byproduct is obtained while extracting the chlorogenic acid composition, so that the production cost is reduced, and the product effectiveness is increased; by adopting the combination of ultrafiltration, macroporous resin and a nanofiltration membrane, the effective content of the chlorogenic acid composition product reaches more than 85wt%, the caffeine content is lower than 1wt%, and the chlorogenic acid composition and the coffee bean oil are good in solubility, and clear and transparent after being dissolved in water, and do not have phase change.

Description

technical field [0001] The invention relates to a method for extracting effective components in plants, in particular to a method for extracting chlorogenic acid composition and coffee bean oil from coffee beans. Background technique [0002] The chlorogenic acid composition extracted and separated from coffee beans has various pharmacological activities such as anti-oxidation, anti-virus, anti-cancer, antibacterial, and cellulite. The latest research by American scientists has found that the chlorogenic acid composition in coffee beans has obvious weight loss function. In addition, coffee bean oil is widely used in cosmetics, food and industry. [0003] The content of chlorogenic acid composition in green coffee beans is 6-9%, while the content of caffeine is 1-3%. Studies have found that excessive intake of caffeine can cause allergies, nausea and insomnia symptoms. Therefore, it is necessary to take measures to reduce caffeine content. At present, the product specifica...
