Abstract
Instant coffee solutions were shown by electron paramagnetic resonance (EPR) spectroscopy to act as prooxidants by enhancing the production of ascorbyl radicals from ascorbic acid. The coffee solutions were als o shown to act as scavengers of superoxide radicals in competition wit h a spin trap. The radical scavenging capabilities of several componen ts of coffee were similarly investigated. There was little difference between the radical scavenging abilities of regular and decaffeinated coffee solutions.
