Microwave heating and conventional heating differ in their mode of heat transfer, heating rate, energy efficiency, and effects on food quality. Microwave heating uses electromagnetic waves, usually at a frequency of 2.45 GHz, which interact with polar molecules such as water, causing rapid molecular vibration and generating heat within the food. In contrast, conventional heating transfers heat from an external source to the food by conduction, convection, and radiation, with heat moving from the surface toward the centre. Microwave heating is much faster because energy is produced directly inside the food, reducing cooking and
