Abstract

Optimization of the EPR signal from the ‘cellulosic’ radical of irradiated plant materials can be achieved with an incident microwave power of approximately 250 μW. This is lower than previously recommended (0.5–2.0 mW) and results in signal intensities of up to 200% greater amplitude. the use of this recommended power in any future EPR‐based detection system will result in fewer false negatives, greater sensitivity, and is more likely to enforce compliance with existing labelling requirements.
