Processed cheese

Some cheese is made to melt well.

It is made by mixing cheese with other things. This helps it stay smooth when it is hot. It can be in blocks or slices.

It stays good for a long time. This cheese is often used on burgers. It can also go on pizza.

People enjoy eating it on many foods.

Processed cheese is a special kind of food.

It is made by mixing cheese with other things. These things are called emulsifying agents. These agents help the cheese stay smooth. When you melt regular cheese, it can get lumpy. The fat and protein might separate. But processed cheese stays creamy when it is hot.

This makes it great for burgers or grilled cheese.

People first made this in Switzerland in 1911. Two men named Walter Gerber and Fritz Stettler did it. They wanted cheese that would last a long time. Later, a man named James L. Kraft found new ways to store it. He used heat to keep it safe.

Today, you can find it in many forms. Some come in big blocks. Some come in small, wrapped slices.

You might see it called cheese food or cheese spread. In the United States, many people call it American cheese. It is often yellow or off-white. Some types, like Provel, are used on pizza.

It is a very useful food for many meals.

Processed cheese is a special kind of food made by mixing real cheese with other ingredients.

It usually contains about 50 to 60 percent cheese. The rest of the mix includes things like salt, vegetable oils, or sugar. Makers also add an emulsifying agent, which is a substance that helps ingredients stay mixed. This agent is often a calcium-sequestering agent like sodium phosphate or citrate. These agents stop calcium from holding cheese proteins together in a tight web. Because of this, the cheese stays smooth instead of getting lumpy when it gets hot.

Making this cheese involves a very interesting way of working with fats and proteins. In natural cheese, fat is trapped inside a network of protein called casein. When you heat natural cheese, the calcium holding the casein together can cause it to separate into liquid fat and lumps. Processed cheese avoids this by using those special agents to break up the casein network. This allows the protein to mix into the fat as tiny, microscopic droplets. The result is a product that melts evenly without separating. This makes it very useful for cooking many different kinds of meals.

The history of processed cheese began in Switzerland in 1911. Two men named Walter Gerber and Fritz Stettler wanted to create a cheese that lasted longer. They were inspired by cheese sauces and fondue. They added sodium citrate to melted Emmentaler cheese and discovered something amazing. The melted sauce could actually be cooled back into a solid block! Later, in 1916, a businessman named James L. Kraft applied for a U.S. patent. His method used sterilization to stop the cheese from aging, which helped it stay safe to eat.

There are many different names and types of processed cheese used today. In the United States, Kraft Foods made the first shelf-stable sliced cheese in 1950. The Clearfield Cheese Co. introduced the first individually wrapped slices in 1956. You might know one famous kind as American cheese, which is often yellow or off-white. Another type is Provel, a blend of cheddar, Swiss, and provolone used on St. Louis-style pizza.

In the United Kingdom, people often call wrapped slices "singles." Some brands include names like Dairylea or The Laughing Cow.

Processed cheese is a very handy ingredient in many homes around the world. Because it does not separate when heated, it is perfect for cheeseburgers or grilled cheese sandwiches. It is much cheaper to make than traditional cheese because it can be produced on a huge scale. This helps keep the cost low and ensures there is always a steady supply for stores. You can find it in many forms, from large blocks to creamy spreads.

Whether it is in a can or a wrapped slice, it helps make melting cheese easy and delicious.

Processed cheese is a unique dairy product created by mixing real cheese with various additives.

It is often known by several different names. These include cheese food, cheese product, or prepared cheese. In many cases, the product contains between 50% and 60% actual cheese. The remaining 40% to 50% consists of other ingredients. These might include salt, vegetable oils, sugar, or food coloring. Some versions also include unfermented dairy ingredients like cream or whey. This combination allows for a wide variety of flavors, colors, and textures.

The chemistry of processed cheese focuses on how it melts. In natural cheese, fat globules are trapped inside a network of protein called casein. Calcium acts as a glue that holds these casein molecules together. When natural cheese is heated, this network often breaks apart. This causes the fat to separate into a liquid layer on top of lumpy protein. To prevent this, makers add a calcium-sequestering agent. This is a substance that stops calcium from holding the casein network together. Common agents include sodium phosphate, potassium phosphate, tartrate, or citrate.

When these agents are added, the casein molecules form much smaller groups. These smaller groups can mix into the fat more effectively during heating. Instead of forming large lumps, they create microscopic droplets. This process ensures the cheese remains smooth and stable when melted. While many people call these substances emulsifiers, they are technically calcium chelators. They do not act as surface-active substances in the strict scientific sense. This chemical control gives processed cheese its famous meltability. It also allows the cheese to resist congealing when cooked in dishes.

The history of this food began in Switzerland in 1911. Two men, Walter Gerber and Fritz Stettler, wanted a cheese with a longer shelf life. They were inspired by the textures found in fondue and cheese sauces. They added sodium citrate to melted Emmentaler cheese to see what would happen. They discovered that the melted sauce could be cooled back into a solid block. Later, in 1916, James L. Kraft applied for a U.S. patent. His method focused on sterilization to halt the maturation process. This helped keep the cheese stable for longer periods.

Further innovations changed how we consume cheese in our daily lives. In 1921, George Herbert Garstin received a U.S. patent for using phosphates. This was a major step in the use of emulsifying salts. By 1950, Kraft Foods developed the first commercially available, shelf-stable sliced cheese. A few years later, in 1956, Clearfield Cheese Co. introduced individually wrapped slices. These convenient forms became very common in American households. They are now frequently used for cheeseburgers and grilled cheese sandwiches. The ability to cook evenly makes them a staple in many kitchens.

There are several distinct types of these products defined by law. In the United States, the FDA regulates these categories. Pasteurized process cheese is made from one or more cheeses mixed with emulsifying salts. It must have a fat content of at least 49 percent. Pasteurized process cheese food must contain at least 51 percent cheese. It can include extra dairy ingredients like milk or whey. Finally, pasteurized process cheese spread is designed to be spreadable. This type has a higher moisture content, between 44% and 60%.

Different regions and brands have their own specific traditions and names. In the United Kingdom, wrapped slices are often called "singles." Leading brands there include Dairylea and The Laughing Cow. In the United States, "American cheese" is a very popular term for a mild, yellow, or off-white variety. Another specific type is Provel, which is used in St. Louis-style pizza. Provel is a blend of cheddar, Swiss, and provolone cheeses.

Because of its mass-produced nature, processed cheese is much cheaper than traditional cheese. This allows for industrial-scale production and a very steady supply for consumers.
