The prerequisite to a shelf-stable packaged macaroni and cheese product was the invention of
processed cheese, where emulsifying salts help
stabilize the product, giving it a longer life. While living in Chicago,
James Lewis Kraft of
Fort Erie, Ontario, began to build his cheese business after winning a patent for one such method in 1916. During the
Great Depression, a
St. Louis, Missouri, salesman, Grant Leslie of
Dundee, Scotland, had the idea to sell macaroni pasta and cheese together as a package, so he began attaching
grated cheese to boxes of pasta with a rubber band. The product was first marketed in many U.S. states in 1936, typically for 15 cents a box (“grated cheese and macaroni--dinner for four in nine minutes”). The box's primary colour changed to blue in 1954, later used in an advertising campaign where children were encouraged to ask for "The Blue Box".
Marye Dahnke, Kraft's resident chef, suggested reviving macaroni and cheese after Kraft was facing competition from
Miracle Whip. A version with spiral-shaped noodles debuted in 1975, while Velveeta Shells & Cheese were introduced in 1984. In 2006, the cheddar and white cheddar versions switched to organic macaroni, while Easy Mac Cups were introduced the same year. In 2007, the noodles switched to 50 percent whole grain. In Europe, food that contains Yellow 5 requires a warning label saying "This product may have adverse effect on activity and attention in children." In 2014, none of the European varieties were made with artificial dyes. In November 2013, Kraft announced that new pasta shape varieties for children in the U.S. would no longer include Yellow 5 and Yellow 6, the sodium and saturated fat content would decrease, and there would be six more grams of
whole grains. In April 2015, it was announced that those changes, including the elimination of artificial preservatives, would be extended throughout
the line after January 2016.
Paprika,
annatto, and
turmeric are used for colouring. According to Kraft, the changes were a response to consumer feedback. In 2018, Kraft-Heinz introduced the KD Shaker, which was a plastic bottle of Kraft Mac and Cheese Dinner's
powdered cheese, allowing one to use the cheese powder as they wish, without needing to worry about unused pasta. The product is similar to shelf-stable Parmesan cheese powder bottle cans. ==Mascot==
