microwave heating

Heating by means of microwaves. Microwave ovens use this form of heating for the rapid cooking or reheating of foods, where heat is generated throughout the interior of the food. If food is not heated completely, there is a danger of bacterial growth that may lead to food poisoning. This method is useful for rapid cooking of frozen and pre-prepared or convenience foods. Industrially, microwave heating is used for destroying insects in grain and enzymes in processed food, pasteurizing and sterilizing liquids, and drying timber and paper.
