Moreover, newer microwave technologies create intriguing opportunities to promote food safety, such as exploring microwave-assisted drying methods Zielinska et. When food is heated in a microwave, the water content in the food is heated, which in turn cooks the food ingredients. Microwaves produce very low-energy electromagnetic radiation, and these waves do not have enough energy to break chemical bonds. Instead, the electromagnetic waves excite electrons in water molecules, causing them to vibrate. According to the Food and Drug Administration FDA , microwaves cause water molecules in the food to vibrate, producing heat that cooks the food. The FDA describes radiation of visible light, radiofrequency, and microwaves as being on the spectrum of non-ionizing electromagnetic radiation. Ionizing radiation such as x-ray or ultra-violet light can damage cells and alter atoms and molecules. However, non-ionizing microwaves are low-energy electromagnetic radiation that does not break elemental bonds. They only interact with the positive and negative regions of molecules, like those found in polar substances like water.
