Cheddar Cheese: How Long Does It Last Sliced?

Sliced cheddar cheese is a popular dairy product that is nutritious, versatile, and tasty. It is important to know how long it lasts, as you would want to avoid eating it if it goes bad. The shelf life of sliced cheddar cheese depends on various factors, such as the storage method, temperature, and moisture content. Proper storage can dramatically extend the refrigerator life of sliced cheddar cheese.

Sliced cheddar cheese's shelf life

Sliced cheddar cheese is a versatile and tasty addition to many dishes. But how long does it last? Well, that depends on a few factors. Firstly, the shelf life of sliced cheddar cheese depends on its moisture content. Soft cheeses with higher moisture content are more perishable and have a shorter shelf life of around one to two weeks in the fridge. In contrast, hard cheeses like aged cheddar have lower moisture levels, which means they last longer—approximately four weeks in the refrigerator.

Secondly, the storage method affects the shelf life of sliced cheddar cheese. Proper storage can dramatically extend the refrigerator life of cheese. For optimal storage, remove the cheese from its plastic packaging and wrap it loosely in a pliable, breathable material like wax paper or cheese paper before placing it in an airtight container. This allows the cheese to breathe and release moisture while protecting it from low humidity in the fridge.

Additionally, the storage temperature is crucial. A safe fridge temperature is below 40°F (4°C). Higher temperatures increase the rate at which bacteria multiply, leading to faster spoilage. Some fridges have built-in thermometers, or you can purchase a fridge thermometer to ensure your appliance maintains a safe temperature.

Finally, the original quality of the cheese and its packaging also influence its shelf life. Unopened sliced cheddar cheese can be stored in its original store packaging and will last much longer than opened cheese—up to six months in the fridge, according to experts.

To extend the shelf life of sliced cheddar cheese even further, you can freeze it. When freezing, wrap the cheese tightly in heavy-duty aluminum foil or plastic freezer wrap, or place it in heavy-duty freezer bags. Frozen sliced cheddar cheese will maintain its best quality for about three months but will remain safe to consume beyond that period.

Storage methods to extend shelf life

Sliced cheddar cheese is a semi-hard cheese, which means it has a longer shelf life than soft cheeses but a shorter shelf life than hard cheeses.

• Keep sliced cheddar cheese refrigerated at all times.
• Store in its original packaging until opened.
• To extend the shelf life, freeze the cheese. First, wrap the cheese tightly in heavy-duty aluminium foil, plastic freezer wrap, or place it in a heavy-duty freezer bag.
• Frozen sliced cheddar cheese will maintain its best quality for 3 months but will remain safe to eat beyond that time.
• Frozen cheese is best suited for cooked dishes, such as sauces, soups, and casseroles, as it may become crumbly and lose some of its flavour.
• To thaw frozen cheese, do so in the refrigerator.
• Once thawed, the cheese can be kept for an additional 3 to 4 days in the refrigerator.
• To store in the refrigerator, remove the cheese from its plastic packaging and wrap it loosely in a pliable yet breathable material, such as wax paper or cheese paper.
• Place the wrapped cheese in an airtight container and store it in the refrigerator.
• Keep the refrigerator temperature below 40°F (4°C).
• Avoid wrapping cheese in tight, non-porous material like plastic wrap, as this can dry out the cheese.
• Do not keep the cheese close to raw meats, poultry, or fish to avoid contamination.

Signs that sliced cheddar cheese has gone bad

Sliced cheddar cheese typically lasts for up to 4 weeks in the fridge, but it's important to know the signs that it has gone bad. Here are some detailed indicators to look out for:

Appearance

A change in appearance is one of the most obvious signs that your sliced cheddar cheese has gone bad. Keep an eye out for any discolouration or a change in the cheese's colour. This could be the cheese turning dark, or developing blue, red, or white spots. If you notice any unusual colours on the surface of your sliced cheddar cheese, it's best to discard it.

Mould

Mould growth is a common issue with cheese, and it can be both desirable and undesirable. Some types of cheese, like Stilton or Brie, are supposed to have mould. However, if mould appears on sliced cheddar cheese, it is most likely unintentional and unsafe to eat. If you see any mould on your sliced cheddar cheese, discard the entire package, as consuming it could lead to foodborne illnesses.

Texture

Any sudden or unusual changes in the texture of your sliced cheddar cheese are a sign that it has gone bad. Pay attention to any hardening, cracking, or a slimy texture. If the cheese feels crumbly, mushy, or very dry when you slice it, it's likely that it has spoiled.

Smell

The smell of cheese can also be a good indicator of whether it has gone bad. Spoiled cheese often develops a strong, unpleasant odour. This could be a rancid, sour, putrid, pungent, or ammonia-like smell. If your sliced cheddar cheese smells unpleasant, it's best to discard it.

Taste

If your sliced cheddar cheese has gone bad, it may taste bitter, acidic, or unpleasantly sour. If you notice any off-tasting flavours, stop consuming the cheese immediately.

Remember, consuming spoiled cheese can lead to food poisoning and other unpleasant symptoms, so it's always better to be cautious and discard any cheese that you suspect has gone bad.

How to store sliced cheddar cheese in the freezer

Sliced cheddar cheese can be stored in the freezer to extend its shelf life. When freezing sliced cheddar cheese, it is important to wrap the cheese tightly to prevent freezer burn and moisture loss. Here are the steps to follow for optimal storage:

Step 1: Timing

Firstly, it is important to note that the cheese should be frozen before the number of days shown for refrigerator storage has elapsed. For sliced cheddar cheese, it is best to freeze it within 3 to 4 weeks of purchasing it from the deli.

Step 2: Wrapping

To wrap the cheese, you can use heavy-duty aluminum foil, plastic freezer wrap, or heavy-duty freezer bags. Ensure that the wrapping is tight around the cheese to prevent air exposure.

Step 3: Freezing

Once the cheese is properly wrapped, place it in the freezer. Frozen sliced cheddar cheese will maintain its best quality for about 3 months but can be stored safely indefinitely at a constant temperature of 0°F (-18°C).

Step 4: Thawing

When you are ready to use the cheese, thaw it in the refrigerator. This will help ensure the best results. Frozen cheese may become crumbly and lose some of its flavor, so it is best suited for cooked dishes like sauces, soups, or casseroles.

By following these steps, you can effectively store sliced cheddar cheese in the freezer, extending its shelf life and maintaining its quality.

Differences between best-by and expiration dates

Sliced cheddar cheese typically has a best-before date of 3-5 days after opening the package. However, it's important to understand the difference between best-before and expiration dates.

Best-before dates indicate when the durable life period of a food product ends. This means that the manufacturer guarantees the product's freshness, taste, nutritional value, and other qualities, only until the specified date, provided it is stored and handled properly. It is important to note that the best-before date no longer applies once the package is opened, and it does not guarantee the safety of the product.

On the other hand, expiration dates are typically required for specific types of food, such as formulated liquid diets, foods sold by pharmacists, meal replacements, nutritional supplements, and infant formula. After the expiration date, the food may not have the same nutrient content as described on the label. Expiration dates usually use phrases like "expires on" or "do not use after," and it is recommended to discard the product after this date.

The key difference between the two is that best-before dates focus on the quality of the product, while expiration dates are related to the safety and nutritional composition of the food. Best-before dates are dependent on proper storage and handling, whereas expiration dates indicate a stronger recommendation to consume the product before the specified date, especially for vulnerable groups like pregnant women, young children, and the elderly.

In summary, while best-before dates provide information about the optimal quality of a product, expiration dates are more critical for ensuring the safety and effectiveness of certain types of food.
