Understanding the Fundamentals of Microwave Processing: A Brief Study of Basic Engineering Mathematical Models

The study of foods has been an interesting subject since the history of mankind, be it intentionally or unintentionally. The way humans evolved has a lot to do with what and how humans consumed the food over the course of time. It all began when the early humans discovered fire and used it as a means to cook the raw food which eventually resulted in tastier foods. Overtime, humans became smarter and their fascination with science led them to discover the unknown and unseen principles of nature that surrounds us all. He began using these principles to his own advantage and one of the purposes was to preserve the foods for a long time. This led to the creation of methods such as salting, curing, smoking, roasting, frying, cooling, drying, and many more. Fast forward to present, we now have advance food processing and preservation techniques such as infrared heating, refrigeration, ohmic heating, and microwave heating, among others. Among these unconventional methods of heating, microwave processing is quite popular in the food
industry. Hence, it is certainly interesting to study about its principle and learn about the
fundamental engineering models that led to the development of the popular heating
appliances- the microwave oven (both domestic and industrial).
