Concern with the physiological effects of caffeine has stimulated research on its analysis in food and biological systems. High-performance liquid chromatographic (hplc) analysis of caffeine in food products requires only the filtration of aqueous extracts and injection onto a suitable column. Detection is frequently based on the measurement of /ív absorption at 280 nm (7).

Capillary electrophoresis has also been used for caffeine determination (10).
