Subcritical water extraction of chlorogenic acid from green coffee beans

A method of extracting chlorogenic acid that does not utilize expensive organic solvents is developed based on the studies of the treatment of green coffee beans by subcritical water. The amount of chlorogenic acid in the obtained extracts is determined using the high performance liquid chromatography (HPLC). A high efficiency of chlorogenic acid extraction by subcritical water as compared to its extraction by ethanol is demonstrated.

Key words: subcritical water, extraction, chlorogenic acid, green coffee, HPLC
