Vacuum sealing is a popular packaging technique in the food industry that prolongs the shelf life of cheese. The process involves removing air from the packaging to prevent oxidation and slow down the deterioration of the cheese. Vacuum-sealed cheese can be stored for several weeks to months, depending on the type of cheese and storage conditions. For example, unopened vacuum-sealed mature cheeses can be stored in the refrigerator for up to 4 to 6 months, while fresh cheeses will only last 3 to 4 days to 1 to 2 weeks. Proper storage techniques, such as maintaining a constant temperature and preventing moisture, are crucial to maximising the shelf life of vacuum-sealed cheese.

What You'll Learn
Vacuum-sealed cheese can last for several months
The shelf life of vacuum-sealed cheese depends on the type of cheese and the storage conditions. For example, unopened vacuum-sealed mature cheeses can be stored in the refrigerator for up to 4 to 6 months, while semi-mature cheeses will last for around 1 to 2 months. Fresh cheeses, such as mozzarella, have a shorter shelf life of 3 to 4 days to 1 to 2 weeks. It's important to note that once the vacuum seal is broken, the cheese will only last for a few days to a few weeks.
Additionally, the moisture content of the cheese affects its shelf life. Relatively dry cheeses with less moisture content can last for months or even years when vacuum sealed. On the other hand, soft and runny cheeses with higher moisture content have more spoilage potential and a shorter shelf life, even when vacuum sealed.
When storing vacuum-sealed cheese, it is recommended to keep it in the refrigerator at a temperature between 4 and 8°C. This will ensure that the cheese remains fresh and safe to consume for several months.
It is worth noting that freezing cheese can affect its taste and texture, especially for soft cheeses. Therefore, it is advisable to use frozen cheese in recipes that require melting.

It's best to use frozen cheese in recipes that require melting
Vacuum sealing is a great way to preserve cheese and prolong its shelf life. It can be stored in the refrigerator for a couple of weeks to a few months, depending on the type of cheese. However, freezing cheese can affect its taste and texture, and it may become drier and crumbly. So, it is best to use frozen cheese in recipes that require melting.
Freezing cheese is a great way to reduce waste and save money, especially if you buy cheese in bulk. When cheese is frozen, small ice crystals form inside, disrupting its internal structure. This can affect the texture and make it crumbly and mealy. Frozen cheese may also be less meltable, especially if stored for a long time. However, freezing inactivates microbes in the cheese, such as bacteria, yeasts, and mould, which helps extend its shelf life.
Hard and semi-hard cheeses, such as cheddar, Swiss, and gouda, are generally well-suited for freezing. These cheeses become crumbly and mealy when frozen but still melt just fine. Mozzarella, pizza cheese, and shredded cheese are also good options for freezing, although their melting properties may be negatively affected. Soft cheeses like brie, Camembert, and ricotta are not ideal for freezing as their texture and taste may be significantly altered.
When using frozen cheese, it is best to grate or crumble it first and then add it to recipes. Frozen cheese can be used in grilled cheese sandwiches, tuna melts, paninis, nachos, casseroles, soups, or even sprinkled on salads. It is important to note that frozen cheese should not be refrozen after thawing.
Overall, vacuum sealing is a great way to extend the shelf life of cheese, but freezing may affect its taste and texture. Therefore, it is best to use frozen cheese in recipes that require melting, such as grilled cheese sandwiches or casseroles.

Vacuum sealing can prolong the shelf life of cheese
Vacuum sealing is a popular packaging technique in the food industry, as it helps prolong the shelf life of cheese. This technique involves removing air from the packaging to prevent oxidation and slow down the deterioration of the cheese. The absence of oxygen, which is the main cause of product decay and bacteria proliferation, helps keep the cheese fresh for a longer period.
Benefits of Vacuum Sealing Cheese
Vacuum sealing offers several advantages over traditional packaging methods:
- It increases the shelf life of cheese, allowing it to be stored for several weeks or even months.
- It provides an effective barrier against light, humidity, and dust, ensuring the cheese remains intact.
- It preserves the quality and organoleptic properties of the cheese, maintaining its taste and texture.
- It is quick and easy to apply, making it a convenient option for both consumers and manufacturers.
- It can be customised with high-definition printing, enhancing the product's presentation.
Factors Affecting the Shelf Life of Vacuum-Sealed Cheese
The shelf life of vacuum-sealed cheese depends on various factors, including the type of cheese, storage temperature, and packaging method.
- Hard cheeses, such as Cheddar, Parmesan, and Gouda, tend to have a longer shelf life compared to soft cheeses like mozzarella, Brie, and cream cheese.
- Vacuum-sealed cheese stored in a refrigerator will last longer than cheese stored at room temperature. The ideal temperature for storing vacuum-sealed cheese is between 4°C and 8°C.
- The use of modified atmosphere packaging, where specific gases like carbon dioxide and nitrogen are inserted instead of air, can further extend the shelf life by creating an environment that inhibits bacterial growth.
Best Practices for Vacuum Sealing Cheese
To maximise the shelf life of vacuum-sealed cheese, it is important to follow certain practices:
- Cut the cheese into smaller blocks before vacuum sealing to facilitate even sealing and prevent air bubbles.
- Wrap the cheese in wax paper before placing it in a vacuum-safe bag to preserve moisture.
- Ensure that most of the air is removed from the bag, and there are no large air bubbles present.
- Store the vacuum-sealed cheese in the refrigerator, ideally between 4°C and 8°C.
- Consume the cheese within the recommended time frame, which is usually a few weeks to a few months, depending on the type of cheese and packaging method.

Vacuum sealing is a competitive advantage for cheese companies
The benefits of vacuum sealing are particularly notable for cheese companies. Cheese is a perishable dairy product, and its shelf life is typically limited, especially for soft and fresh cheeses. However, with vacuum sealing, companies can extend the lifespan of their products, reducing waste and increasing customer satisfaction. This technique is effective for both hard and soft cheeses, although higher moisture content in soft cheeses can impact shelf life.
Vacuum sealing also provides a barrier against light, humidity, and dust, further preserving the quality of the cheese. Additionally, the packaging can be customised to enhance product presentation, making it more appealing to consumers. This is especially beneficial for companies selling cheese as a premium or specialty product.
The extended shelf life offered by vacuum sealing provides logistical advantages for cheese companies. It enables companies to distribute their products over longer distances and facilitates the export of cheese to international markets. This expands the customer base and opens up new revenue streams, giving cheese companies a competitive edge in the global marketplace.
Furthermore, vacuum sealing can be combined with refrigeration for even greater preservation. For instance, vacuum-sealed mature cheeses can be stored in a refrigerator for up to 4 to 6 months, while fresh cheeses can last for 3 to 4 days to 1 to 2 weeks. This flexibility in storage conditions provides cheese companies with the ability to cater to diverse consumer needs and preferences.

Hard cheeses are easier to freeze than soft cheeses
Vacuum sealing is a great way to preserve cheese for longer. However, it's important to note that freezing cheese can alter its taste and texture. The impact is usually more noticeable in soft cheeses.
Hard cheeses are generally easier to freeze than soft cheeses. This is because soft cheeses have a higher moisture content, which means more water will be converted to ice crystals during freezing. As a result, their structure can be significantly damaged, leaving you with a pool of cheese when it's thawed.
Hard and semi-hard cheeses, such as cheddar, Swiss, and blue cheese, can be frozen, but they will become crumbly and mealy, and more difficult to slice. Their texture and melting properties may also be negatively affected. However, they will still melt just fine, making them suitable for recipes that require melted cheese.
Mozzarella, a semi-soft cheese, can be frozen but is more likely to be successful when shredded. Freezing mozzarella blocks is possible but will not last as long as harder cheeses.
Soft cheeses like Brie, Camembert, ricotta, and cottage cheese are not recommended for freezing due to their high moisture content. Freezing these cheeses can cause undesirable flavour changes and significantly damage their structure.
To summarise, hard and semi-hard cheeses can be frozen but may become crumbly and difficult to slice. Soft cheeses can be frozen but are more likely to suffer from structural damage and flavour changes. When deciding whether to freeze cheese, consider the intended use and the type of cheese. Freezing is generally better for cooked dishes than for eating fresh.
