American Cheese: How Long Does It Last In The Fridge?

American cheese is a versatile ingredient that can be used in both warm and cold dishes. It is a popular choice for sandwiches and burgers due to its creamy texture and meltability. The shelf life of American cheese varies depending on factors such as the form it is sold in and whether it is processed or real cheese. In general, 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 the best taste and quality.

To get the most out of your cheese, it's important to store it properly. American cheese slices should be kept in the centre of the fridge, where temperatures are coolest, and ideally between 35°F and 40°F. Avoid storing cheese in the fridge door, as this can affect its quality.

When storing American cheese slices, it's best to wrap them loosely in a breathable material like wax paper or cheese paper, and then place them in an airtight container. Avoid using tight, non-porous materials like plastic wrap, as this can dry out the cheese and make it harder.

If you want to extend the shelf life of your American cheese slices, you can freeze them. However, freezing cheese can change its texture, making it crumbly. When freezing, wrap the cheese tightly in heavy-duty aluminium foil or plastic freezer wrap, or place it in a heavy-duty freezer bag. Properly stored, frozen cheese will maintain its best quality for about eight months, but it will remain safe to eat beyond this time.

Unopened American cheese can last in the fridge for 4-6 months

The shelf life of unopened American cheese in the fridge depends on its moisture content. American cheese has a low moisture content, which means it is less prone to spoilage from bacteria. This is because moisture is needed for bacterial growth, so cheeses with higher moisture levels have a shorter shelf life.

However, it is important to note that the shelf life of American cheese can be affected by storage conditions. To maximize the shelf life of unopened American cheese, it should be stored in the refrigerator at all times and kept in its original store packaging until ready to use. The refrigerator temperature should be below 40°F (4°C) to ensure the cheese remains safe to eat.

Additionally, American cheese can be frozen to further extend its shelf life. When freezing, wrap the cheese tightly in heavy-duty aluminum foil or plastic freezer wrap, or place it in heavy-duty freezer bags. Properly stored, American cheese will maintain its best quality for about 8 months in the freezer, but it will remain safe beyond that time if kept at a constant temperature of 0°F (-18°C).

American cheese should be stored at a temperature of 35-40°F

Storing cheese at this temperature slows down metabolic activity and the multiplication of microorganisms in the cheese. This means the cheese remains edible for longer and does not spoil as quickly as it would at room temperature.

To ensure your refrigerator is at the correct temperature, you can purchase a fridge thermometer. Place the thermometer in the warmest spot, usually near the door, rather than tucked away at the back of the fridge.

When storing American cheese in the refrigerator, it is important to wrap it in a porous material such as cheese or wax paper. This will help to maintain the cheese's moisture. Avoid using tight, non-porous materials like plastic wrap, as this can dry out the cheese.

In addition to maintaining the correct temperature and using the right wrapping, it is also important to store cheese away from raw meats, poultry, and fish to avoid contamination.

American cheese can be frozen for up to 8 months

To freeze American cheese, it's recommended to wrap the cheese tightly in heavy-duty aluminum foil or plastic freezer wrap, or to place it in a heavy-duty freezer bag. This helps to prevent freezer burn and maintain its quality. It's best to consume frozen American cheese within 6 to 9 months for optimal quality.

Frozen cheese is best suited for cooked dishes where changes in texture are less noticeable, such as sauces, soups, casseroles, or grilled cheese sandwiches. It may not be ideal for dishes that require melting, as freezing can affect its melting properties.

While freezing can extend the shelf life of American cheese, it's worth noting that refrigeration is also an option. An unopened package of American cheese slices can last up to 1 month after the date on the package when properly refrigerated.

Signs of spoilage include mold, discoloration, and an off smell or taste

It is crucial to recognise the signs of spoilage in American cheese to ensure safety and prevent food poisoning. Changes in appearance, texture, smell, and taste can indicate that the cheese has gone bad.

Visual and Textural Changes

The presence of any type of mold, whether green, black, or white spots, is a clear indication that the cheese should not be consumed. Discoloration, such as yellowing or darkening beyond the cheese's normal colour, could also be a sign of spoilage. If the edges of the cheese appear dried out or hardened, or if the surface feels slimy or tacky, it is likely no longer fresh.

Off Smells and Altered Tastes

American cheese that has spoiled may emit a sour or unpleasant odour, distinct from its typically mild, creamy scent. It may also develop an unusual or sour taste, which confirms that it is not fit for consumption.
