Processed cheese is a blend of natural cheese, milk, preservatives, and food coloring. It is often sold as slices or spreads. Once opened, processed cheese spreads will generally last for about 1 to 2 weeks if continuously stored in a refrigerator. To maximize shelf life, wrap the cheese in wax paper or parchment paper and then in plastic wrap or aluminum foil. This will help to prevent the cheese from drying out and absorbing other flavors or odors in the fridge.

What You'll Learn
Processed cheese should be consumed within a week of opening
Processed cheese is a convenient and tasty option, but it's important to consume it within a week of opening to ensure optimal quality and safety. Here's why:
Processed cheese, such as cheese spreads or slices, has a relatively short shelf life once opened. The shelf life of any food product depends on various factors, including storage conditions, temperature, and exposure to contaminants. By limiting the consumption of processed cheese to within a week of opening, you can reduce the risk of spoilage and potential foodborne illnesses.
Proper storage is crucial to maintaining the quality and safety of processed cheese. After opening, store the cheese in its original packaging or wrap it tightly in plastic wrap or aluminium foil. Ensure that it is kept in the main part of the refrigerator, where the temperature is typically between 33°F and 40°F. The refrigerator door is warmer and should be avoided as it can accelerate spoilage.
Additionally, always inspect your cheese before consumption. While processed cheese may be consumed within a week of opening, it can still spoil before this time frame, especially if not stored properly. Look for signs of spoilage, such as mould growth, a darker colour, or an unusual odour. If you notice any of these indicators, discard the cheese immediately.
Furthermore, it's important to note that processed cheese should not be left at room temperature for extended periods. If kept above 40°F, processed cheese will rapidly spoil and should be discarded if left out for more than two hours.
By following these guidelines and consuming processed cheese within a week of opening, you can ensure a safer and more enjoyable experience. Proper storage and regular inspection of your cheese will help maintain its quality, flavour, and texture while reducing the risk of foodborne illnesses.

It should be stored in the original packaging or wrapped in plastic wrap/foil
To ensure the quality and flavour of processed cheese is preserved, it is important to store it correctly. Processed cheese, such as American cheese and cheese slices, should be stored in the original packaging or wrapped in plastic wrap or aluminium foil. This will help to prevent the cheese from drying out and absorbing other flavours or odours in the fridge. It is also crucial to store cheese at the correct temperature. The ideal temperature range is between 33°F and 40°F, which is usually found in the main part of the refrigerator, not the door.
The original packaging of processed cheese is designed to keep the product fresh. It is airtight and helps to maintain the correct moisture levels, preventing the cheese from drying out. It also acts as a barrier, protecting the cheese from absorbing other flavours or odours that may be present in the fridge. Therefore, it is best to keep the cheese in its original packaging for as long as possible.
If the original packaging is not available, or if the cheese has been opened and needs to be wrapped again, plastic wrap or aluminium foil can be used. Plastic wrap provides a tight seal that prevents air circulation and moisture loss. It also creates a barrier that protects the cheese from absorbing other flavours or odours. Aluminium foil has similar properties and can be used as an alternative to plastic wrap. When using plastic wrap or aluminium foil, ensure that the cheese is wrapped tightly, with no gaps or holes, to create an effective barrier.
It is important to note that once the cheese has been removed from its original packaging and wrapped in plastic wrap or aluminium foil, it should be consumed within one week. This is because the cheese is now exposed to air and bacteria, which can cause spoilage and affect the flavour and texture. Therefore, it is recommended to only wrap the cheese in plastic wrap or aluminium foil if it can be consumed within a week.

It should be stored in the main part of the fridge, not the door
The temperature of your fridge is crucial to preserving the quality and flavour of your cheese. The main body of the fridge is typically between 33°F and 40°F, which is ideal for storing cheese. The door of the fridge is the warmest part, and temperatures above 40°F will cause soft cheese to spoil rapidly. Therefore, it is important to store cheese in the main part of the fridge, not the door.
A safe fridge temperature is below 40°F (4°C). Higher temperatures significantly increase the rate at which bacteria multiply, which raises the risk of food spoilage. Some fridges have built-in thermometers, but if yours doesn't, you can purchase a fridge thermometer to ensure it stays at a safe temperature. Place the thermometer in the warmest spot (near the door), not tucked away in the back.
When storing cheese, wrap it in wax, parchment, or cheese paper, and then place it in the top or middle shelf or in a drawer. Avoid wrapping cheese in tight, non-porous material like plastic wrap, as this can dry it out and harden it. Also, keep cheese away from raw meat, poultry, and fish to avoid contamination.
If you have leftover cheese that you can't finish within a week, you can freeze it. However, keep in mind that the texture and flavour may change. When freezing cheese, wrap it tightly and place it in a freezer-safe container or plastic bag. Label the cheese with the type and date it was frozen.

It can be frozen for up to two months
If you have any leftover processed cheese, it can be frozen for up to two months. This is a great way to preserve your cheese, but it's important to note that the texture and flavour may change once it has been frozen and thawed. This method works best for hard and semi-hard cheeses, while soft and blue cheeses may become crumbly and have a different texture.
When freezing cheese, make sure to wrap it tightly in plastic wrap or aluminium foil. Place it in a freezer-safe container or plastic bag, ensuring that it is protected from moisture and other contaminants. Label the cheese with the type and date it was frozen. This will help you keep track of how long it has been frozen and ensure that you consume it within the two-month period.
It is crucial to store cheese at the correct temperature to maintain its quality and flavour. The ideal temperature range for storing cheese in the refrigerator is between 33°F and 40°F. Avoid storing cheese in the door of the refrigerator, as this is the warmest part. Instead, keep it in the main part of the refrigerator.
Additionally, proper storage of cheese after opening is essential. Wrap the cheese in wax or parchment paper and then in plastic wrap or aluminium foil. This will help prevent the cheese from drying out and absorbing other flavours or odours in the refrigerator. Keep cheese away from raw meat or seafood to prevent contamination.

Freezing may affect the texture and flavour
When it comes to the longevity of processed cheese spread, one of the critical factors to consider is the impact of freezing on its texture and flavour. While freezing can extend the shelf life of many foods, including cheese spreads, it's important to understand the potential changes it can bring about.
Freezing processed cheese spread may alter its texture and consistency. This is because the freezing process can cause the separation of oils and other components in the cheese spread. As a result, you may find that the spread becomes slightly drier and crumblier in texture after thawing. Additionally, freezing can affect the creaminess and smoothness typically associated with processed cheese spreads.
The flavour of the processed cheese spread may also undergo subtle changes when frozen. Freezing can affect the distribution of flavour compounds within the spread, potentially resulting in a milder or slightly altered taste. This change in flavour is usually not significant, but sensitive palates may detect a difference. It's worth noting that the impact on flavour is generally less noticeable compared to the textural changes.
To minimise the effects of freezing on texture and flavour, it's recommended to thaw the processed cheese spread gradually and safely. Place it in the refrigerator and allow it to thaw slowly over several hours or overnight. Rapid thawing at room temperature or using a microwave may exacerbate the textural changes and impact the flavour more noticeably.
It's important to manage expectations when freezing and thawing processed cheese spread. While it may not have the exact same creamy texture and flavour as the fresh product, it will still be safe to consume and can be used in various dishes. Consider using the thawed cheese spread in cooked applications, such as in grilled cheese sandwiches, casseroles, or as a topping on baked potatoes, as the heat can help mask any minor textural or flavour changes.
