Food Irradiation and Its Benefits

Electromagnetic radiation spans a wide range of wavelengths, including sunlight, which is crucial for life. Different types of waves have various applications: radio waves for communication, microwaves for cooking, infrared for warmth, visible light for illumination, ultraviolet for vitamin D, X-rays for medical diagnostics, and gamma rays for sterilization. Irradiation using X-rays and gamma rays can treat food by preventing spoilage and eliminating harmful bacteria and insects. This process is chemical-free and maintains food quality, offering a safe alternative to traditional methods.

Which type of electromagnetic wave is primarily used for cooking food?
