Powdered Parmesan cheese, like all other forms of Parmesan, has a long shelf life. However, it does not last forever and will eventually go bad. Proper storage is essential to prolonging the shelf life of Parmesan cheese. This includes storing it in an airtight container in the refrigerator to prevent it from drying out or absorbing odours. When stored properly, an unopened package of Parmesan cheese can last several months beyond its expiration date. Once opened, Parmesan cheese should be sealed and stored in the refrigerator, where it will last for several weeks to months.

What You'll Learn
Powdered parmesan cheese shelf life
Parmesan cheese has a long shelf life, especially when stored properly. The shelf life of powdered parmesan cheese varies depending on the brand and whether it is opened or unopened.
Unopened powdered parmesan cheese can last for several months beyond the expiration date, as long as it is stored properly. For example, Kraft's grated parmesan cheese, which is usually shelf-stable, can be good for about a year. On the other hand, refrigerated grated parmesan cheese may only last a week or two after opening.
To extend the shelf life of opened powdered parmesan cheese, it should be stored in an airtight container or resealable bag in the refrigerator. It is best to use a fresh spoon or tongs when scooping out the cheese to add to a dish, and to prevent the cheese from touching other food. Additionally, it is important to pay attention to any signs of spoilage, such as mould growth, off odours, or changes in texture or colour. If mould is spotted on hard cheeses like parmesan, it is generally safe to cut off the affected portion, and the rest of the cheese should still be usable.

Proper storage methods
Powdered Parmesan cheese can go bad, but it has a long shelf life. Proper storage is key to preventing it from spoiling.
If you have bought a large quantity of powdered Parmesan cheese, it is best to divide it into smaller portions and store it in well-sealed containers. This will help to prolong its freshness.
The ideal storage temperature for powdered Parmesan cheese is between 35°F to 46°F (2°C to 8°C). It should be stored in the refrigerator, preferably in the bottom compartment, to prevent it from absorbing odours from other foods.
You can also store powdered Parmesan cheese in the freezer, especially if you want to extend its shelf life. Freezing the cheese will not affect its taste or texture and will keep it fresh for longer.
When storing powdered Parmesan cheese, always ensure that it is tightly sealed and placed in an airtight container. This will prevent moisture from entering and affecting the cheese.
In addition to refrigeration and airtight storage, it is recommended to use wax paper or parchment paper to wrap the cheese. This will help to preserve the cheese's humidity and prevent it from drying out.
By following these proper storage methods, you can extend the shelf life of your powdered Parmesan cheese and enjoy its rich flavour for a longer period of time.

Freezing powdered parmesan
Parmesan cheese is a hard cheese with a low water content, which means it has a long shelf life. However, it can still go bad. To prevent this, it should be stored in a cool, dry place. While freezing is not necessary for powdered Parmesan, it can be frozen.
Freezing is a good option if you have bought a large amount of Parmesan and want to store it for later use. It can be kept in the freezer for a long time, and this will not affect its taste or texture. However, it is important to ensure that the cheese is wrapped in paper rather than stored in a sealed plastic container, as this will prevent a buildup of condensation.
If you are freezing powdered Parmesan, it is important to note that the cheese should be stored in an airtight container or storage bag before being placed in the freezer. This will prevent it from being affected by the surrounding air and moisture in the freezer.
It is also worth noting that, while Parmesan has a long shelf life, once it is grated or cut off the block, its shelf life is shortened. Therefore, freezing grated Parmesan is a good option if you want to prolong its shelf life.

Differences between fresh and store-bought cheese
Parmesan cheese is considered a hard cheese with a low moisture content. This means that it has a long shelf life and will dry out quickly more often than it will go bad. Fresh parmesan is usually sold as a block of cheese, which can be grated or cut into slices or shreds. Store-bought parmesan, on the other hand, is often sold in grated or shredded form, either in a bag or a container.
One of the main differences between fresh and store-bought parmesan cheese is the shelf life. Fresh parmesan, when stored properly in an airtight container in the fridge, can last up to a year. On the other hand, store-bought grated parmesan will only last about 7 days after opening but can stay good for months if stored properly.
Another difference is the texture and taste. Fresh parmesan has a unique texture and feel to it. It needs to be grated or shaved, and it may clump when it sits, so it needs to be used faster. Store-bought parmesan, on the other hand, is already grated or shredded, which makes it more convenient to use. However, some people find that store-bought parmesan has a distinctive off-flavour and tastes like "white wood dust".
In terms of price, store-bought parmesan can be more expensive than fresh parmesan, especially if it is a well-known brand like Kraft. However, it is important to note that fresh parmesan may also vary in price depending on the quality and the place of purchase.
Finally, it is worth mentioning that both fresh and store-bought parmesan cheese can be frozen to extend their shelf life. However, some people argue that freezing cheese can affect its flavour and texture.
