Who invented frozen foods?
There are three types of frozen foods. 1) food that is frozen slowly. 2) food that is flash frozen. This food is frozen faster to preserve the texture and best flavors, normally done to vegetables. 3) Snap frozen foods. This is any food dipped into liquid nitrogen. It is super cold and if you drop or bend the food, it will snap or shatter like glass.
An American inventor, Clarence Birdseye, developed quick frozen foods in the late 1920's. He sold his process to a company that later became General foods, and they released his amazing collection of frozen vegetables, fruit and meats to the American public in 1930. They were instantly popular and remain so today.
