MADISON, Wis. (AP) â?? Edwin Traisman, a food scientist who created the process for freezing McDonald’s french fries and helped develop Cheez Whiz, has died at age 91.
Desiring a return to research, he went as a program manager at the University of Wisconsin-Madison’s Food Research Institute in 1970. In 1987, he helped initiate research on E. coli, which was then a little-known pathogen, according to a university news release. He was later inducted into the Wisconsin Meat Industry Hall of Fame.
