摘要：
The spontaneous precipitation of caffeine from black coffee bean extracts obtained by extraction with supercritical carbon dioxide has been found. This effect is observed for various types of coffee when using pressure values of the supercritical extractant on the order of 40-50 MPa. Two valuable products, caffeine and decaffeinated coffee oil, can be obtained by the simple centrifugation of CO2 extracts of coffee beans, which can be used in the food and cosmetic industries.
