Pat McMillion of Burritt on the Mountain in Huntsville, Alabama, wrote, “The cheese monger at our local Publix told me today that the only difference between white and yellow American cheese is that dye is added…. ever since the Civil War when dye was added to tell the difference between cheese produced in the north and cheese produced in the south. That really sounded mythical to me, but I haven’t found any substantiation on the web. Is that a myth, legend or truth?”
Well, Pat, you have stumbled into one of my deepest secrets with this question. I will now have to confess that for three years after I graduated from college, I sold cheese for Kraft Foods in Cleveland, Ohio. (It was a recession, for heaven’s sake, so I was lucky to have a job at all!) Kraft sent me to cheese factories to learn all about processed cheese, white cheese, orange cheese, Cheez Whiz, Velveeta, and every sort of cheese, and I can personally assure you that American cheese (aka processed cheese) was not around during the Civil War.
J. L. Kraft invented American cheese and started producing it in 1915; he got the patent in 1916. It was originally sold in tins and was white. Because it was the middle of World War I, the Army bought up lots and shipped it to our soldiers in Europe. Yum!!!
Later, I don’t know when exactly, orange color was added, but this old advertisement dates from the Twenties, and it shows that it was orange by then.
