American cheese is a processed cheese made from a blend of two or more real cheeses, typically cheddar and Colby, along with other ingredients like whey, milk proteins, vitamins, colouring, and emulsifying agents. It has a smooth, creamy texture and a salty flavour, making it a popular choice for grilled cheese sandwiches, burgers, and other dishes. While it may not be considered real cheese by some, it has a significant place in American cuisine and is widely consumed. The term American cheese specifically refers to this processed variety, which was invented in the 1910s by James L. Kraft, the founder of Kraft Foods Inc.

What You'll Learn
Milk and whey are added to the blend of cheeses
The process of making American cheese involves blending at least 51% cheese with other ingredients, including milk and whey. This blend is then heated and pasteurized, with sodium citrate added to prevent the cheese fats from separating. The final product is packaged in various forms, such as individually wrapped slices, stacks of unwrapped slices, or unsliced blocks.
The milk used in cheesemaking can come from different sources, including cows, goats, sheep, and even water buffalo. Each type of milk produces a unique kind of cheese with distinct flavours and textures. For example, goat's milk cheese has a mildly acidic and zingy flavour, while sheep's milk cheese is rich, smooth, and sometimes sweet.
The addition of milk and whey to the blend of cheeses in American cheese serves several purposes. Firstly, it adds moisture and contributes to the overall texture of the cheese. Secondly, the proteins in milk and whey help to bind the mixture and create a smooth, homogeneous blend. This prevents the cheese from separating when heated, ensuring a consistent melt.
The use of milk and whey in American cheese also has practical and functional benefits. By adding these ingredients, manufacturers can control the percentage of milkfat, moisture content, and overall consistency of the final product. This allows for a cheese that is easily meltable and adaptable to various recipes, such as grilled cheese sandwiches, cheeseburgers, and breakfast dishes.

Pasteurization is required to kill harmful organisms
Pasteurization is a process of food preservation in which packaged foods, such as milk, are treated with mild heat to eliminate harmful organisms and extend shelf life. This process is named after French microbiologist Louis Pasteur, whose research in the 1860s demonstrated that heating wine could deactivate unwanted microorganisms. Pasteurization is a precise process that heats milk to specific temperatures for a set period of time to kill bacteria and germs without altering the nutrition or taste of the product.
The process of pasteurization is an important step in the production of American cheese, which is a type of processed cheese made from cheddar, Colby, or similar cheeses, in conjunction with sodium citrate. This additive prevents the cheese from separating during pasteurization, which is done at a minimum temperature of 150 °F (66 °C) for at least 30 seconds. Pasteurization is required for American cheese to ensure the safety of the product and to meet regulatory standards for commercial food products.
In the United States, most milk and milk products sold commercially contain pasteurized milk or cream. Pasteurization is necessary to kill harmful bacteria that can lead to serious illnesses and diseases, such as listeriosis, typhoid fever, tuberculosis, diphtheria, and brucellosis. The consumption of raw milk and unpasteurized dairy products may be harmful to health due to the presence of dangerous bacteria.
The four types of milk that the FDA has deemed acceptable for cheesemaking are cow, water buffalo, goat, and sheep milk. Each type of milk produces a unique kind of cheese with distinct flavours and textures. For example, goat's milk has a mildly acidic, zingy flavour, while sheep's milk cheese is rich, smooth, and sometimes sweet.
While pasteurization is crucial for food safety, it is important to note that it does not affect the nutritional content of milk. Research has shown that pasteurized milk is just as nutritious as raw milk, and both types can cause allergic reactions in individuals sensitive to milk proteins. Pasteurization also does not extend the shelf life of milk indefinitely, and pasteurized milk should still be stored in the refrigerator and consumed before the expiration date.

Milk proteins are added to improve meltability
Milk proteins are added to American cheese to improve its meltability. American cheese is a processed cheese, typically made from a blend of "real" cheeses, such as cheddar and Colby, along with other ingredients. The addition of milk proteins is a crucial step in achieving the desired texture and meltability that American cheese is known for.
The process of making American cheese involves grating and melting the "real" cheeses together, forming a homogeneous mixture. This mixture is then combined with milk proteins, whey, and emulsifying agents. The role of milk proteins is essential in enhancing the cheese's meltability by creating a smooth and cohesive texture. This prevents the cheese from breaking or turning greasy when melted, a common issue with traditional cheeses.
The emulsifying agents, such as sodium citrate, play a crucial role in preventing the separation of cheese fats during pasteurization. This ensures that the cheese maintains a consistent texture and appearance. Additionally, the milk proteins contribute to the overall flavour and body of the final product.
The specific requirements for processed American cheese dictate the percentage of milkfat, moisture content, salt levels, and pH value. These factors, along with the added milk proteins, contribute to the unique characteristics of American cheese. The meltability of American cheese is a defining feature, making it a popular choice for dishes such as grilled cheese sandwiches, cheeseburgers, and macaroni and cheese.
While American cheese may not be considered "real" cheese by some due to its processed nature, it has a significant impact on the culinary landscape of its namesake country. The addition of milk proteins is a key factor in achieving the desired meltability and texture that has made American cheese a staple in various dishes and a favourite among cheese lovers.

Emulsifying agents are added to bind the mixture
American cheese is a processed cheese made from cheddar, Colby, or similar cheeses. It has a smooth and creamy texture, a salty flavour, and a low melting point. During its production, emulsifying agents are added to bind the mixture and ensure the cheese does not separate.
The emulsifying agents used in American cheese are typically sodium citrate, emulsifying salts, or trisodium citrate. These additives are crucial in preventing the cheese fats from separating during the pasteurization process. Sodium citrate, in particular, is an important additive as it allows the cheese to be pasteurized without its components separating. This additive is also used in macaroni and cheese and other cheese sauces.
Federal laws mandate that "pasteurized process American cheese" must be entirely cheese, except for the inclusion of an emulsifying agent, salt, colouring, acidifying agents, and optional dairy fat sources (not exceeding 5% of the total weight). This distinction is important, as products labelled as "cheese food" or "cheese spread" may contain less than 51% cheese and include other dairy ingredients such as cream, milk, skim milk, buttermilk, cheese whey, or albumin from cheese whey.
The addition of emulsifying agents to American cheese contributes to its unique characteristics, such as its smooth texture and meltability. This makes it a popular choice for dishes like grilled cheese sandwiches, macaroni and cheese, cheeseburgers, and various breakfast meals.

American cheese is made from cow's milk
American cheese is a type of processed cheese that is made from a combination of "real" cheeses, such as cheddar and Colby, along with other ingredients like whey, milk proteins, and emulsifying agents. According to regulations, for a product to be labelled as "American cheese", it must be manufactured from cheddar, Colby, washed curd cheese, or granular cheese, or any mixture of these.
The process of making American cheese involves blending and melting the cheeses with other ingredients to form a homogeneous mixture. This mixture is then heated to a temperature of at least 150 °F (66 °C) during pasteurization. The composition requirements for American cheese control the percentage of milk fat, moisture, salt, and pH value, along with specifications for flavour, texture, colour, and meltability.
While American cheese may not be considered "real" cheese by some, it is important to note that all cheese is processed to some extent. The term "processed cheese" refers to cheese made from a blend of two or more types of "real" cheese, as defined by the FDA. The processing of cheese involves treating milk, typically from cows, with rennet, an enzyme derived from the stomach lining of an unweaned calf or vegetable-based sources.
Cows' milk is one of the four types of milk that the FDA has approved for cheesemaking, along with milk from water buffalo, goats, and sheep. Each type of milk lends distinct flavour and texture characteristics to the resulting cheese. Cow's milk cheeses can range from soft to hard, similar to goat cheeses, and the milk itself serves as the basis for a wide variety of cheeses, including the famous cheddar.
In summary, American cheese is made from a blend of cheeses, primarily cheddar and Colby, which are typically produced using cows' milk. The processing and blending of these cheeses with additional ingredients give American cheese its unique characteristics, such as meltability and smoothness.
