American cheese is everywhere — in burgers, on sandwiches, melted over fries, or layered into casseroles. It’s a staple in many households, known for its smooth melt and mild flavor. But how did this processed cheese become so deeply rooted in American food culture? And what exactly is it?
This article explores the origins, evolution, and quirky facts behind American cheese — from dairy farms to factory lines and fast food menus.
What Is American Cheese?
American cheese is a type of processed cheese made by blending one or more natural cheeses — typically cheddar and Colby — with emulsifiers and other ingredients. These additives help it melt uniformly and extend its shelf life. The result is a smooth, mild-flavored cheese that’s ideal for grilling, melting, and slicing.
You’ll most often see American cheese in individually wrapped slices, commonly referred to as “singles.” Though widely labeled as “cheese,” many products legally must be called pasteurized process cheese food or cheese product due to their lower real cheese content.
Why It Melts So Well
American cheese melts better than many traditional cheeses because it contains emulsifiers such as sodium phosphate. These compounds prevent the proteins in cheese from separating from fat when heated. The consistency stays smooth, not oily or clumpy.
The Origins of American Cheese
Early Factory Cheese
The roots of mass cheese production in the U.S. date back to 1851. Jesse Williams, a farmer in New York, developed one of the first factory-style cheese operations. This new method increased output and quality consistency. By the late 1800s, America was exporting large amounts of cheese — often cheddar — to Europe, especially the United Kingdom. British customers called it “American cheese,” though it wasn’t yet the processed kind we know today.
Kraft’s Big Breakthrough
The processed version of American cheese as we know it began with James L. Kraft. Born in Canada, Kraft moved to Chicago in 1903 with just $65 and a horse-drawn wagon. He started a wholesale cheese business but ran into the problem of spoilage.
In response, Kraft experimented with ways to extend cheese’s shelf life. In 1916, he patented a method for making processed cheese. This involved shredding cheddar scraps, heating them, and adding emulsifying salts like sodium phosphate. The process resulted in a smooth, longer-lasting cheese that wouldn’t spoil quickly.
At the same time, Swiss chemists Walter Gerber and Fritz Stettler were developing similar methods using sodium citrate to stabilize cheese. However, it was Kraft and his brother Norman who brought the product to market and made it a commercial success.
Rise in Popularity
A Wartime Staple
American cheese became especially popular during World War I and World War II. Its long shelf life, portability, and consistent quality made it ideal for feeding soldiers. The U.S. military distributed processed cheese in rations, helping cement it as a familiar and trusted food.
Mainstream Adoption
By the 1930s, processed cheese accounted for nearly 40% of cheese consumption in the United States. In 1950, Kraft introduced individually wrapped slices, which made the product even more convenient for consumers. In 1965, Kraft acquired the rights to the patented plastic wrap used for packaging singles.
This innovation made American cheese a perfect fit for the booming fast-food industry. It became the default cheese for burgers, grilled cheese sandwiches, and other quick-service foods.
Government Regulations
Not everyone was a fan of Kraft’s invention. Traditional cheesemakers lobbied the U.S. government to distinguish real cheese from processed products. In response, the Food and Drug Administration (FDA) created strict labeling guidelines.
Products made with at least 51% cheese could still be called “processed cheese.” Those with less were labeled cheese food or cheese product. This is why Kraft Singles are technically not cheese — they contain less than the required 51% real cheese and must be labeled as “pasteurized process cheese food.”
Additionally, the FDA described processed cheese as a “homogeneous plastic mass,” highlighting its manufactured nature.
Fun and Fascinating Facts
1. Wisconsin, Cheese Capital
Wisconsin has led U.S. cheese production since 1910. The state produces over 3 billion pounds of cheese annually. American cheese is just one of many types produced, but it has helped earn Wisconsin’s reputation as a cheese hub. The term “cheeseheads” for Green Bay Packers fans stems from this dairy heritage.
2. Cheese by Another Name
During early production, critics mocked American cheese as “embalmed cheese.” The name came from sodium phosphate — also used in embalming fluid — being one of the main emulsifiers. Thankfully, the term never stuck.
3. Original Color: White
American cheese originally appeared white, as it was mostly made from white cheddar. The yellow-orange hue seen today comes from annatto, a natural coloring also used in traditional cheddar to give it a rich golden tint.
4. American vs. Swiss Influence
While Kraft developed the product in the U.S., the Swiss were simultaneously working on similar processed cheese using Emmental. The term “American cheese” became more common in the 1920s, partly for marketing to U.S. consumers with patriotic preferences.
5. Velveeta Connection
Kraft acquired Velveeta in 1927. Velveeta’s recipe involved whey, making it even more meltable than Kraft’s processed cheese. The acquisition helped Kraft refine its American cheese formula and solidify its dominance in the processed cheese market.
6. Government Cheese
In the 1980s, the U.S. government distributed “government cheese” to low-income families. This surplus came from dairy subsidies and consisted largely of processed American cheese. It was part of the Temporary Emergency Food Assistance Program under President Reagan.
7. Nutrition Profile
American cheese provides calcium and protein but is also high in saturated fat and sodium. While it offers some nutritional value, excessive consumption may raise health concerns, especially for those with heart or blood pressure issues.
Types of American Cheese Products
-
Pasteurized Process Cheese: Contains more than 51% cheese.
-
Pasteurized Process Cheese Food: Contains less than 51% cheese and additional dairy ingredients.
-
Pasteurized Process Cheese Product: Contains even fewer dairy solids and may use milk protein concentrate.
-
Imitation Cheese: Made without real cheese, often from vegetable oils.
Reading the label is the best way to know what you’re getting. Kraft Singles, for example, fall into the “cheese food” category, not actual cheese.
The Legacy of American Cheese
Today, American cheese continues to be a defining ingredient in American cuisine. Whether you’re biting into a classic cheeseburger or enjoying a grilled cheese sandwich, chances are good you’re eating some form of processed American cheese.
It may not be gourmet, but it’s practical, reliable, and undeniably American.
