Easily quantifying free radicals allows for the detection of irradiated foods, measurement of radiation levels, and analysis of biological samples.
The tabletop electronic spin resonance (ESR) device "Magnettech ESR5000" can non-destructively observe free electrons or unpaired electrons (free radicals) directly within samples, making it a versatile product widely applicable in fields such as food, chemistry, and pharmaceuticals. Since it can trace the generation and reactions of radicals, it is useful in the food sector for measuring antioxidant capacity, assessing the deterioration of oils, and observing the flavor stability of beer, among other applications. In the medical field, free radicals are said to be involved in various diseases such as aging, cancer, and arteriosclerosis, allowing for their evaluation. Additionally, imported foods are irradiated for purposes such as sterilization, pest control, and sprout prevention, and the device can also detect the radicals generated during this process, leading to expectations that ESR devices will replace traditional TL methods as irradiation food detection devices.
