What is vacuum-sealed cheese?
Vacuum-sealed cheese is cheese that has been packaged in an airtight environment, removing most of the air from the package before sealing it. This process helps to minimize oxidation and maintain the quality of the cheese for a longer time than traditional packaging methods. Vacuum sealing also helps prevent the growth of mold and bacteria, making it an effective method for preserving various types of cheese.
This method is often used for both block cheese and sliced cheese, making it convenient for consumers. The vacuum-sealing process also retains the cheese’s flavor and texture, allowing it to be stored for extended periods without significant loss of quality. Thus, many people choose vacuum-sealed cheese for both its practicality and its extended shelf life.
How long does vacuum-sealed cheese last?
The shelf life of vacuum-sealed cheese varies depending on the type of cheese and the storage conditions. Generally, vacuum-sealed cheese can last between six months to a year, sometimes even longer if stored correctly in a refrigerator or freezer. Hard cheeses, such as Parmesan and cheddar, tend to have longer shelf lives compared to softer cheeses like Brie or mozzarella when vacuum sealed.
Once opened, the longevity of the cheese decreases significantly. Soft cheeses, for example, may only last a week or two, while hard cheeses can still last a few weeks to several months if properly resealed and refrigerated. It’s crucial to monitor the cheese for any signs of spoilage, such as discoloration, off-odors, or mold, which may indicate that it’s no longer safe to eat.
