Parmesan cheese is a hard cheese with a low moisture content, which means it can be left out without spoiling for longer than soft cheeses. However, it is still recommended to refrigerate it to keep it fresh and preserve its quality. Powdered Parmesan, in particular, is made with a dehydration process, which further reduces the risk of the cheese going bad. So, is it okay to leave powdered Parmesan cheese unrefrigerated?

Powdered Parmesan is best stored in the fridge
Hard cheeses like Parmesan can be left out at room temperature for up to two hours. After this time, bacterial growth may occur, and the cheese should be discarded. To prevent food waste, it is best to refrigerate Parmesan and other hard cheeses as soon as possible.
The shelf life of Parmesan can be extended by storing it in an airtight container or resealable bag in the refrigerator. This will also help to prevent the cheese from drying out or absorbing odours. When stored properly, Parmesan can last for several weeks to months in the refrigerator.
It is also important to inspect Parmesan cheese for any signs of spoilage before consumption. If there are any noticeable changes in colour, texture, or smell, it is advisable to closely examine the cheese and determine if it is still suitable for consumption. If there is any mould on the cheese, it is generally safe to cut off the affected portion and use the rest. However, if there is any doubt about the safety of the cheese, it is best to discard it.
By following these storage guidelines and regularly inspecting the cheese, consumers can ensure that their powdered Parmesan remains safe and fresh for as long as possible.

It can be left at room temperature for up to an hour
Powdered Parmesan cheese is a convenient way to store this popular dairy product. Parmesan is a hard cheese with a low moisture content, which means it can be left at room temperature for longer than soft cheeses without spoiling.
While it is generally recommended to store cheese in the refrigerator, there are times when it is left out, such as when serving a cheese board or using a cheese shaker in a restaurant. The general rule of thumb is that hard cheeses like Parmesan can be left out for up to two hours, but should be discarded if left out overnight.
However, to maintain the quality and freshness of powdered Parmesan cheese, it is best to follow the manufacturer's recommendations. Kraft, for example, advises that its cheeses be stored in the refrigerator at a temperature of 40 degrees Fahrenheit and only kept at room temperature for up to one hour. This is because cheese is a dairy product, and milk is typically kept refrigerated to stay fresh.
Leaving powdered Parmesan cheese at room temperature for longer than an hour may increase the risk of bacterial growth and reduce its shelf life. Proper storage is essential to keeping the flavor and texture of Parmesan cheese at its best. To extend the shelf life of opened Parmesan cheese, it is recommended to store it in an airtight container or resealable bag in the refrigerator.

It lasts several weeks to months when stored in the refrigerator
Parmesan cheese has a long shelf life, especially when stored correctly. When stored in the refrigerator, Parmesan cheese can last for several weeks to months. The shelf life of Parmesan cheese depends on several factors, such as the storage conditions, type of packaging, and whether it has been grated or shredded.
If stored in the refrigerator, unopened Parmesan cheese in its original packaging can last for several months beyond its expiration date. However, once the package is opened, its shelf life decreases. Grated or shredded Parmesan has a shorter shelf life compared to a block or wheel of Parmesan. To extend the shelf life of opened Parmesan cheese, it is recommended to store it in an airtight container or resealable bag in the refrigerator.
The refrigerator temperature should be maintained below 40°F (4°C) to ensure the cheese remains fresh and its quality preserved. Proper sealing is essential to prevent the cheese from drying out or absorbing odours from other foods in the refrigerator. Additionally, it is advisable to inspect the cheese for any signs of discoloration, foul odours, moisture, or mould before consumption. If any of these issues are present, it is recommended to discard the cheese.
Parmesan cheese is a hard cheese with a lower moisture content, which contributes to its longer shelf life compared to soft cheeses. It can be left at room temperature for a short period, but it is generally recommended to store it in the refrigerator to maintain its flavour and texture. Proper storage ensures that Parmesan cheese remains safe for consumption and retains its peak flavour and texture.

Unopened, it can last beyond its expiration date
Powdered Parmesan cheese can last a long time without refrigeration, but whether or not it needs to be refrigerated depends on several factors. Firstly, it is important to distinguish between “real” Parmesan cheese and other varieties of powdered cheese marketed as “Parmesan".
Real Parmesan cheese is made in a specific region of northern Italy from local cow's milk using specific historical methods and is aged for a minimum of about one year. The cheese has a relatively long shelf life, especially when stored properly. When stored in the refrigerator under the right conditions, Parmesan can last for several weeks to months. If the Parmesan cheese is unopened and still in its original packaging, it can last for several months beyond its expiration date.
Hard cheeses like Parmesan have lower moisture content and can sit out longer without spoiling. They are less likely to promote bacterial growth and can last longer without refrigeration. This is because grating or shredding hard cheeses requires dehydration, evaporation, and then cooling to reduce the fat from oozing out and making the cheese clump. The reduction of fat compounds slows the risk of the cheese going bad.
However, it is important to note that even hard cheeses like Parmesan should not be left at room temperature for extended periods. Most cheeses should only be left at room temperature for two hours. To keep cheese safe, it is generally recommended to store it in the refrigerator. If you notice any discoloration, foul odours, or moisture on grated Parmesan, it is advisable to throw it out.

If mouldy, cut off the affected area and the rest is usable
Powdered Parmesan cheese is a hard cheese with a low moisture content, which means it can be left out without spoiling for longer than soft cheeses. However, to keep it fresh and preserve its quality, it should be refrigerated.
If you notice mould on the surface of hard cheeses like Parmesan, it is generally safe to cut off the affected portion, and the rest of the cheese will still be usable. However, it is important to inspect the cheese closely and consider other factors such as colour, texture, and smell to determine if it is still suitable for consumption.
When it comes to storing Parmesan cheese, it is recommended to keep it in an airtight container or resealable bag in the refrigerator. This will help maintain its freshness and prevent it from drying out or absorbing odours. The ideal temperature for storing Parmesan cheese is below 40°F (4°C).
It is worth noting that the shelf life of Parmesan cheese depends on various factors, including whether it is unopened, opened, grated, or in block form. If stored properly, unopened Parmesan can last for several months beyond its expiration date. Once opened, its shelf life depends on how well it is sealed and stored. Grated Parmesan may have a shorter shelf life compared to a block of Parmesan.
To summarise, while it is not strictly necessary to refrigerate powdered Parmesan cheese, doing so will help maintain its freshness and quality. If mould is spotted, it is safe to cut off the affected area, but always use your judgment and inspect the cheese for any other noticeable changes before consumption.
