The general public first started taking notice of the microwave oven in
1975 when sales volume, for the first time, exceeded 1,000,000 units per
year! In 1985, ovens were owned by over 50070 of U. S. households, and
food compa- nies were developing microwavable products in earnest.
During this period microwave product developers found that very little
information was avail- able to assist them with their task. Microwave
ovens utilized a technology that was completely different from
conventional and weIl-understood cook- ing procedures. The interaction
of microwaves with foods behaved in a mysterious fashion, and product
development was, at best, guesswork and, at least, trial and error. This
lack of knowledge of both the microwave oven and microwave-food
interaction spurred the development of this text. Microwave technology
was developed du ring World War 11 when the best scientists in the
United States were cloistered at the radiation labora- tory at MIT. In
the 1940s virtuaIly aIl the technology that could impact the microwave
oven was developed and weIl understood. The problem was in the
translation of this decades-old knowledge to rules and techniques to be
used for food product development. Early authors such as Püschner and
Copson wrote texts primarily on applications to industrial processing.
This knowledge lay faIlow as these texts went out of print.
