What You'll Learn
Why does American cheese melt so easily?
American cheese is processed cheese that is designed to melt extremely well and is nearly impossible to break. It was invented in Switzerland to reduce cheese waste by melting scraps from various cheese batches into a new product. In 1916, Canadian-American entrepreneur James Kraft perfected and patented the technique in the US, and it soon became popular due to its long shelf life and ease of shipping.
The melting properties of American cheese can be attributed to its ingredients and processing methods. It is made by blending real cheese, usually a young cheddar-style variety, with extra milk for added water content, milk protein micelles for a strong protein structure, and chemical salts to prevent proteins from tightening. This excess liquid gives American cheese an extremely low melting point, resulting in its characteristic gooey texture when melted.
The addition of milk protein micelles and chemical salts helps to stabilize the cheese's protein structure, preventing it from breaking down during melting. This is in contrast to other cheeses, where the protein structure can break apart when heated, causing the fat globules to separate and form a greasy pool while the proteins congeal into a stringy mess.
The melting properties of American cheese make it a popular choice for dishes like grilled cheese sandwiches, cheeseburgers, and queso dip. However, it is important to note that the focus on texture and meltability comes at the cost of a less intense flavor compared to other cheeses.
To enhance the melting capabilities of American cheese even further, additional techniques can be employed. For example, steaming the cheese can introduce more water, ensuring even and gentle heating. Additionally, the use of starch or thickeners can impede fat molecules from joining into larger droplets, improving the texture of the melted cheese.

What is the science behind melting cheese?
Cheese is an emulsion of dairy fat and water, held together by a network of proteins called casein. When cheese is heated, the protein molecules break apart from this structure, freeing the other parts to become fluid. However, melting—strictly defined as a phase change from a solid to a liquid—isn't really happening, as the cheese becomes fluid by bringing some parts together and excluding others.
The melting properties of cheese depend on its temperature, composition, acid level, and age. The younger the cheese, the stretchier and smoother it will melt; the older the cheese, the clumpier and harder it will be to break down. This is because, as cheese ages, its proteins break down and become more enmeshed, forming stronger bonds that require higher temperatures to break down.
Higher moisture cheeses like young Gouda or Mozzarella are good melting cheeses. Drier cheeses like aged Gouda and Parmigiano Reggiano won't melt as well unless there is added moisture. Similarly, higher-fat cheeses like Havarti usually melt better than low-fat cheeses.
The level of acid in the cheese also affects its meltability. Acid-set cheeses like goat cheese, farmer's cheese, paneer, queso fresco, and ricotta do not melt because acid dissolves the calcium that holds the casein proteins together. Instead, when an acid-set cheese is heated, its proteins move closer together, and water is cooked off, resulting in a lack of melting action.
To improve the meltability of cheese, more fat or water can be added to soften it. This can be done by steaming the cheese or adding milk or cream. Additionally, shredding the cheese increases its surface area, allowing it to melt more quickly, and bringing it to room temperature reduces the amount of heat energy required to melt it.

What is the exact melting point of American cheese?
American cheese is a processed cheese made from a blend of natural cheese, milk, and other ingredients. It is known for its mild, creamy flavour and smooth, plastic-like texture that melts easily. The exact melting point of American cheese is not known, however, it is said to have a low melting point. This is due to the high moisture content in the cheese, which makes it more pliable and easy to melt. The manufacturing process of American cheese involves adding excess liquid, which contributes to its low melting point.
During the production of American cheese, traditional cheese is ground and combined with emulsifying agents, sodium citrate, and other ingredients. The mixture is then heated to a temperature of at least 150 °F (66 °C) during pasteurization. This temperature can be considered a reference point for the melting point of American cheese, as it is the minimum temperature required for the cheese mixture to become a homogeneous mixture.
The low melting point of American cheese makes it a popular choice for dishes that require melted cheese, such as grilled cheese sandwiches, cheeseburgers, and cheese melts. Its smooth and meltable texture allows it to act as an adhesive layer in dishes like cheeseburgers, helping to maintain their form. American cheese is also used in dishes like macaroni and cheese, breakfast sandwiches, and nachos, where its melting properties are desirable.
The melting point of American cheese can be influenced by various factors, such as the specific blend of cheeses used, the amount of added liquids, and the presence of emulsifying agents. Additionally, the heating method and the temperature at which the cheese is heated can impact its melting behaviour. For example, heating American cheese too quickly or at too high a temperature can cause the proteins to seize up and release moisture, resulting in a greasy texture instead of a smooth, melted one.
Overall, while the exact melting point of American cheese may vary depending on its specific composition, it is known for having a low melting point due to its high moisture content and the addition of excess liquids during production. This low melting point makes American cheese a versatile and popular choice for dishes requiring melted cheese.

How does the melting point of American cheese compare to other cheeses?
The melting point of a cheese depends on its ratio of water to fat, as well as the strength of its protein network. Younger, high-moisture cheeses with a higher fat content tend to melt better than drier, low-moisture cheeses.
American cheese has a much lower melting point than most other cheeses. This is because it is made with excess liquid, emulsifiers, and preservatives, such as sodium citrate, which help the cheese emulsify and prevent the separation of fats and proteins during melting. This results in a smooth and creamy texture when melted, making it ideal for sauces, grilled cheese sandwiches, and cheeseburgers.
On the other hand, some cheeses, such as paneer, feta, ricotta, and queso fresco, do not melt well due to their high acidity. These cheeses are curdled with acid rather than rennet, causing the cheese to release water instead of melting when heated.
Compared to other cheeses, American cheese's melting point is significantly lower, making it a popular choice for dishes requiring melted cheese, such as grilled cheese sandwiches and cheeseburgers. However, this high meltability comes at the cost of a less intense flavor.
Other factors that affect the melting ability of cheese include moisture, fat content, and age. Cheeses with more moisture, higher fat content, and younger age tend to melt more easily than drier, lower-fat, and aged cheeses. For example, Red Leicester melts more easily than its cousin Cheddar due to its higher fat content. Similarly, Brie and Camembert are high-moisture cheeses that melt easily, while Parmesan and Pecorino-Romano are drier and harder to melt.

What is the best way to melt American cheese?
American cheese is a type of cheese that is designed to be extremely meltable and nearly impossible to break. Its low melting point makes it ideal for grilled cheese sandwiches or cheeseburgers.
To melt American cheese, you can use a stove or a microwave. If you're using a stove, start with a cold pan and grate your cheese before adding it to the pan. This will ensure that the cheese doesn't burn. Use one of the lowest settings on your stove and let the pan and cheese come up to temperature together. If you're using a microwave, place the cheese in a microwave-safe container, preferably non-stick, and add a dash of corn starch and evaporated milk. This will prevent the cheese from becoming lumpy. Heat the cheese in small increments until it starts to melt. You can also add a slice or two of American cheese to your cheese mixture as it has properties that help other cheeses melt smoothly.
To make a queso dip, bring some heavy cream to a simmer in a pot and then add slices of American cheese. You can add the cheese in stages, letting each addition melt before adding more. You can also add other flavorings like onion, peppers, salt, garlic, cumin, and chili powder.
If you're making nachos, you can make a cheese sauce by blending cheese with water, milk, or another liquid. To prevent the cheese from becoming stringy, you can add starch or a melting salt, which will allow the cheese to be heated beyond its melting point without losing its emulsion.
