The Aging Of American Cheese: How Long Does It Take?

American cheese is a processed cheese made by blending different types of cheese, such as cheddar and Colby, and adding other ingredients to improve its melting ability. It is often sold in individual slices and is a popular choice for sandwiches and burgers. The shelf life of American cheese varies depending on its form and whether it is processed or real cheese. Generally, unopened American cheese can last in the refrigerator for up to four months, while individual slices should be consumed within two to three weeks of opening to maintain optimal taste and quality. Proper storage is crucial to preserving the quality and safety of American cheese, and it should be stored at a constant temperature between 35-40°F in the fridge.

American cheese is aged for three months or less

American cheese is a processed cheese that is aged for three months or less. It is made by combining cheeses like cheddar and Colby and adding other ingredients to help it melt smoothly. It is often sold in individual slices and is a popular cheese for burgers and sandwiches. Its smooth melting ability comes from the emulsifiers that help prevent milk proteins from separating from the milk fat when heated.

American cheese is considered a "process cheese" by the FDA, meaning that it is either made by combining two or more types of cheese or by adding other ingredients such as milk proteins, whey, or emulsifiers. For it to be considered cheese, at least 51% of the product must be cheese. This is in contrast to products like Velveeta, which is termed a "process cheese food" because it contains less than 51% cheese.

American cheese typically comes in two varieties: orange or white. The orange colour comes from the addition of annatto, a Central American berry used for colouring. White American cheese contains no colouring.

In terms of storage, American cheese can last for 5 to 6 months in the refrigerator if it is individually wrapped. If bought sliced at a deli counter, it should be consumed within 2 to 3 weeks and kept in the original deli paper. It can also be frozen for 6 months or more with little loss of quality.

It's made from a blend of cheddar and Colby cheeses

American cheese is a processed cheese made from a blend of cheddar and Colby cheeses, along with sodium citrate, which acts as an emulsifying agent to prevent the cheese from separating during pasteurization. This blend of cheeses results in the characteristic mild, creamy, and salty flavour of American cheese, with a medium-firm consistency and a low melting point.

Cheddar and Colby cheeses, the base of American cheese, have distinct characteristics that contribute to the final product. Cheddar cheese undergoes a "cheddaring" process, where the curds are drained and stacked before being cut and cooked. This process results in a harder cheese with a sharper, more pungent flavour that intensifies with age. On the other hand, Colby cheese is made by eliminating the cheddaring process and instead partially draining the whey and adding cold water to reduce the temperature. This method yields a softer, moister, and milder cheese with a more open texture.

The combination of these two cheeses creates a blend that takes on the best qualities of each. The mild flavour and creamy texture of American cheese make it a versatile ingredient in various dishes, from grilled cheese sandwiches to cheeseburgers, casseroles, and salads. It is also a popular choice for snacks and cheese platters due to its smooth, meltable texture.

In terms of storage, American cheese can last for up to four months in the refrigerator if unopened. Once opened, it is recommended to consume it within two to three weeks to maintain optimal taste and quality. Proper storage techniques, such as consistent refrigeration at a temperature between 35-40°F, are crucial for preserving the cheese's freshness and preventing spoilage.

It's a process cheese according to the FDA

According to the FDA, pasteurized process cheese is a food prepared by combining and mixing, with the aid of heat, one or more cheeses of the same or two or more varieties (excluding some types of cheese such as cream cheese, cottage cheese, and skim-milk cheese for manufacturing). The cheese is heated for at least 30 seconds at a temperature of at least 150°F. The moisture content of pasteurized process cheese is typically no more than 43%, and the fat content is at least 47%.

The FDA's definition of pasteurized process cheese includes the use of an emulsifying agent, such as monosodium phosphate or trisodium phosphate, to ensure a homogeneous plastic mass. Additionally, acidifying agents like vinegar or lactic acid can be added to adjust the pH, and harmless artificial coloring is permitted.

The FDA also specifies that pasteurized process cheese in consumer-sized packages may include mold-inhibiting ingredients like sorbic acid and lecithin as an anti-sticking agent. Furthermore, the FDA requires that the name of the cheese on the label includes any flavoring or spice that characterizes the product.

In summary, the FDA defines pasteurized process cheese as a blend of specific types of cheeses, heated and combined with particular additives, resulting in a homogenous product with regulated moisture and fat content.

It's sold in blocks or individual slices

American cheese is a versatile product, often sold in blocks or individual slices. The shelf life of American cheese varies depending on its form, whether it is processed or 'real' cheese, and the way it is packaged.

Blocks

American cheese is formed into solid blocks and sold at delis, where it can be sliced to order. Blocks of American cheese can be stored in the refrigerator for up to four months if unopened, and for two to three weeks if opened.

Individual Slices

Individually-wrapped slices of American cheese will last for five to six months if unopened and stored in the refrigerator. If you buy it pre-sliced at the deli counter, it should be consumed within two to three weeks.

Packaging

The original packaging of American cheese helps prolong its longevity. Manufacturers typically package American cheese in sealed plastic wraps or wax paper to ensure freshness and prevent contamination. Once the seal is broken, American cheese should be stored in an airtight container or securely wrapped to prevent air exposure.

It's best consumed within two to three weeks of opening

American cheese is a versatile ingredient that can be used in both warm and cold dishes. It is known for its creamy texture and meltability, making it a popular choice for sandwiches and burgers. While unopened American cheese can last in the refrigerator for up to four months, it is best consumed within two to three weeks of opening to maintain optimal taste and quality.

Proper storage is crucial to preserving the cheese's freshness and safety. American cheese should be stored in the fridge at a constant temperature between 35-40°F. To ensure optimum freshness, it is recommended to store the cheese in an airtight container or securely wrap it with plastic wrap or aluminum foil. Labelling the cheese with the opening date can help track its freshness accurately.

It is important to note that American cheese is sensitive to temperature fluctuations. Steady temperature control is essential to prevent spoilage and slow down bacterial and mould growth. Additionally, exposure to air and moisture can accelerate spoilage, so it is important to reseal the packaging between uses.

To maximise the shelf life of American cheese, it can be frozen. However, freezing may alter the texture and affect its meltability. For best results, wrap the cheese tightly in heavy-duty aluminium foil or plastic freezer wrap, or place it in heavy-duty freezer bags.

American cheese is susceptible to spoilage, and it is important to recognise the signs. These include texture changes, such as discoloration or the presence of mould, and odor changes, such as an off-smell distinct from its typical milky, buttery aroma. If any signs of spoilage are detected, it is best to discard the cheese to prevent potential health risks.
