Cheese Storage: Sliced Cheese Shelf Life Explained

Sliced cheese is a convenient food item to have in the fridge, but how long does it last unopened? The answer depends on the type of cheese and the storage conditions. For example, unopened sliced American deli cheese can last for 6-8 months in the fridge, while sliced cheddar deli cheese has a similar shelf life of 6-8 months. However, it's important to note that these cheeses are at their best quality during this time period. When it comes to Kraft cheese, sources suggest that unopened slices can last for up to two months beyond the printed expiration date, which is typically about five to six months after production.

Sliced cheese can be refrigerated for 2-4 weeks

For American cheese, the expiration date is generally about five to six months after production. However, unopened slices can last up to two months beyond the printed date. Once the package is opened, the slices should be consumed within a week.

Cheddar cheese has a similar shelf life to American cheese when stored in the refrigerator. It can be kept in its original store packaging and should not be opened until ready to use.

To extend the shelf life of sliced cheese, it can be frozen. When freezing, wrap the cheese tightly in heavy-duty aluminum foil or plastic freezer wrap, or place it in heavy-duty freezer bags. Frozen cheese will maintain its best quality for about 3-8 months but will remain safe to consume beyond that time if stored at a constant temperature of 0°F.

It is important to note that freezing cheese can alter its flavor and texture, making it crumbly and less meltable. Therefore, it is recommended to consume sliced cheese within the refrigeration time frame if possible.

Unopened sliced cheese should be kept in its original packaging

Unopened sliced cheese should always be kept in its original packaging. This is the best way to store it and will help to maximise its shelf life. The packaging is designed to keep out moisture and other contaminants, and to ensure the cheese can breathe. This is why it's best not to wrap cheese in cellophane, as this can suffocate it.

The original packaging will also help to keep the cheese fresh. For example, sliced American deli cheese can be kept unopened in its original store packaging for 6-8 months. This is because the cheese has been processed and contains preservatives. However, it's important to remember that the cheese will only stay fresh for this length of time if it is stored correctly, i.e. refrigerated at all times and kept below 40°F.

If you want to extend the shelf life of unopened sliced cheese, you can freeze it. However, this is not recommended as it can alter the flavour and texture of the cheese. If you do decide to freeze your cheese, make sure to wrap the slices tightly in heavy-duty aluminium foil or plastic freezer wrap, or place them in a heavy-duty freezer bag.

It's also worth noting that the type of cheese will affect its shelf life. Harder, aged cheeses will generally last longer than softer, less mature cheeses.

To extend shelf life, wrap sliced cheese in aluminium foil and freeze

To extend the shelf life of sliced cheese, it is recommended to wrap it tightly in heavy-duty aluminium foil and place it in the freezer. This method can increase the shelf life of sliced cheese by several months.

When freezing cheese, it is important to ensure that it is properly protected from the elements. Aluminium foil provides an effective barrier, preventing the cheese from drying out or becoming contaminated by excess moisture, off-flavours, or mould.

To maximise the shelf life of sliced cheese, it is recommended to follow these steps:

• Wrap the sliced cheese tightly in heavy-duty aluminium foil or plastic freezer wrap. Alternatively, place the cheese in a heavy-duty freezer bag.
• Place the wrapped cheese in a freezer-safe bag and squeeze out any excess air before sealing.
• Label the cheese with the date and type before placing it in the freezer.
• Thaw the cheese slowly in the refrigerator when ready to use. Avoid thawing at room temperature to prevent texture changes.

It is important to note that freezing cheese can affect its texture and versatility. Frozen cheese is best suited for cooking applications, such as melting into casseroles, sauces, or gratins, rather than serving fresh.

Frozen sliced cheese is safe to eat indefinitely

Sliced cheese can be stored in the refrigerator for 6-8 months, and even longer if frozen. While cheese is best enjoyed fresh, freezing is a great way to extend its shelf life, reduce waste, and save money.

Freezing cheese is simple. First, portion the cheese into quantities that you are likely to use at once. For large blocks of cheese, it is recommended to not freeze more than one pound per portion. Next, wrap the cheese in foil or cheese paper, or place it in a freezer bag. If using the latter, ensure you remove as much air as possible from the bag. Finally, place the wrapped cheese in an airtight container or bag and store it in the freezer.

When stored in the freezer, sliced cheese will maintain its quality for about eight months, but it is safe to eat beyond that. In fact, frozen sliced cheese can be kept indefinitely in the freezer if stored at a constant temperature of 0°F. However, for the best quality, it is recommended to consume it within six to nine months.

Once you are ready to use the cheese, thaw it in the refrigerator. Depending on the type and size of the cheese, this can take anywhere from a few hours to overnight. It is important to note that once cheese has been frozen and thawed, it should not be refrozen.

Freezing cheese can cause changes in texture and quality. When cheese is frozen, small ice crystals form on the inside, disrupting its internal structure. As a result, the cheese may become drier, crumbly, and mealy when thawed. Frozen cheese may also be less meltable, especially if stored for a longer period. Therefore, frozen sliced cheese is best suited for cooked dishes where changes in texture are less noticeable, such as sauces, soups, casseroles, or grilled cheese sandwiches.

Signs of spoiled cheese include an off odour, flavour or appearance

Sliced cheese lasts for about 6-8 months when unopened and refrigerated. However, it's important to know the signs of spoiled cheese to ensure food safety and prevent foodborne illnesses. Signs of spoiled cheese include an off odour, flavour, or appearance.

Off Odour: Spoiled cheese may emit a sour, ammonia-like, or otherwise funky smell, indicating the presence of harmful bacteria.

Off Flavour: Spoilage bacteria and mould can break down proteins and fats in cheese, resulting in off-flavours like sourness, bitterness, or a burning sensation.

Off Appearance: Look for mould or discolouration. Fuzzy green, blue, or white patches on the surface are a tell-tale sign of spoilage. Additionally, a change in colour, such as a creamy white cheddar turning yellowish or greyish, indicates that the cheese has gone bad. Spoiled cheese may also exhibit a different texture, becoming slimy, sticky, or wet, or developing a tough, dry texture that crumbles easily.

It's important to note that some cheeses, like Brie or Camembert, naturally have a soft, runny texture, so use your best judgement and consider the other signs of spoilage before discarding the cheese.
