Parmesan cheese is a hard cheese that originated in Italy. It is made by heating cow's milk and adding lactic acid bacteria to lower the pH, followed by rennet for coagulation. Parmesan has a wide variety of uses and can be enjoyed as a snack or by health enthusiasts as a satisfying treat. When it comes to packaged Parmesan cheese, the shelf life depends on various factors such as sealing, storage, and whether it is grated or shredded. Properly stored Parmesan can last for several months beyond its expiration date if unopened and still in its original packaging.
| Characteristics | Values |
|---|---|
| Storage | Parmesan cheese should be stored in the refrigerator at temperatures below 40°F (4°C). Opened packages of Parmesan should be kept in an airtight container or resealable bag. For grated or shredded Parmesan, use a vacuum-sealed bag or a container with a tight lid. |
| Shelf Life | Unopened Parmesan cheese can last for several months beyond the expiration date if stored properly. Once opened, the shelf life depends on factors such as sealing and storage. Grated or shredded Parmesan may have a shorter shelf life compared to blocks or wheels. |
| Spoilage | Signs of spoilage include mould growth, off odours, or changes in texture and colour. If mould is present, it is generally safe to cut off the affected portion and consume the rest of the cheese. |
| Freezing | Parmesan cheese can be frozen. It is recommended to cut the cheese into smaller blocks and place them in a freezer bag. |

Unopened and properly stored Parmesan cheese can last for several months beyond its expiration date. The best place to store it is in the refrigerator at temperatures below 40°F (4°C). It is also important to ensure that the cheese is well-sealed to prevent it from drying out or absorbing odours from the refrigerator.

To extend the shelf life of Parmesan cheese beyond these periods, you can freeze it. Parmesan cheese can be frozen in an airtight container or freezer bag. When freezing shredded Parmesan cheese, it can last for three to six months in the freezer. On the other hand, a wedge of Parmesan cheese will stay in the freezer for over a year.
It is important to note that frozen cheese may become crumbly and lose some of its flavor. Therefore, it is best suited for cooked dishes, such as sauces, soups, and casseroles. After defrosting Parmesan cheese, it can be kept for an additional 3 to 4 days in the refrigerator.
