Parmesan cheese is a hard, dry cheese that is often grated and shredded. Due to its low moisture content, Parmesan does not need to be refrigerated and can be stored at room temperature. However, refrigeration can extend its shelf life. Proper storage is essential to maintaining the flavour and texture of Parmesan cheese. It is recommended to store Parmesan in the refrigerator at temperatures below 4°C, ensuring that it is well-sealed to prevent drying out or absorbing odours. For grated or shredded Parmesan, using a vacuum-sealed bag or a container with a tight lid is advisable.

Parmesan's low moisture content makes it less susceptible to bacteria
Parmesan is a hard, dry cheese with a low moisture content, which means it can be left out of the refrigerator without spoiling. This is because the low moisture content makes it less susceptible to harmful bacteria. In addition, Parmesan has a pH level of around 5.2-5.3 due to leftover lactic acid, and this acidity helps to kill any bad bacteria.
The low moisture content of Parmesan is due to its hard, dry texture. This texture is a result of the cheese's aging process, during which much of the moisture evaporates. This process also contributes to the cheese's long shelf life.
While it is not necessary to refrigerate Parmesan, doing so can help extend its lifespan even further. Refrigeration can slow down the growth of bacteria and prevent the cheese from drying out or absorbing odours. For this reason, it is generally recommended to store Parmesan in the refrigerator, especially if it is grated or shredded.
When storing Parmesan in the refrigerator, it is important to ensure that it is well-sealed. This will help to prevent the cheese from drying out or absorbing other odours from the refrigerator. Using a vacuum-sealed bag or a container with a tight lid can help to keep the cheese fresh and extend its lifespan.
In summary, Parmesan's low moisture content, resulting from its hard and dry texture, makes it less susceptible to bacteria and, therefore, safe to store at room temperature. However, refrigeration can further extend its lifespan and is generally recommended, especially for grated or shredded Parmesan. Proper sealing and storage are crucial to maintaining the quality and freshness of this cheese.

Refrigeration can help dry Parmesan last longer
Parmesan cheese is a hard, dry cheese that is often grated and shredded. Due to its low moisture content, it is less susceptible to harmful bacteria and does not require refrigeration. However, refrigeration can help extend its shelf life even further.
When storing Parmesan cheese in the refrigerator, it is important to maintain a temperature below 40°F (4°C). Proper sealing is also crucial to prevent the cheese from drying out or absorbing refrigerator odours. Grated or shredded Parmesan can be stored in a vacuum-sealed bag or a container with a tight lid.
The key to preserving the flavour and texture of Parmesan cheese is proper storage. While refrigeration is not mandatory, it can be beneficial. At room temperature, most cheeses can only be left out for two hours. By refrigerating Parmesan, you can slow down the spoilage process and maintain its quality for a more extended period.
Additionally, it is essential to inspect the cheese for any signs of spoilage, such as mould growth, unusual odours, or changes in texture. If mould is detected on hard cheeses like Parmesan, it is generally safe to cut off the affected portion and use the remaining cheese. However, it is always advisable to use your judgment, consider the specific storage conditions, and follow any storage instructions provided on the packaging.
In summary, while dry Parmesan cheese does not require refrigeration, doing so can help prolong its freshness and maintain its optimal flavour and texture. Proper sealing and storage conditions are crucial to ensuring the best quality of this popular cheese.

Proper storage is essential to maintaining Parmesan's flavour and texture
When storing Parmesan cheese, it is important to keep it well-sealed to prevent it from drying out or absorbing odours from the refrigerator. Grated or shredded Parmesan should be stored in a vacuum-sealed bag or a container with a tight lid. The ideal temperature for storing Parmesan in the refrigerator is below 40°F (4°C).
If you choose not to refrigerate your Parmesan, it is recommended to wrap it in food-grade paper or aluminium foil and store it in a cool, dark, and dry area. This will help protect it from spoilage and maintain its quality.
It is also important to regularly inspect your Parmesan cheese for any signs of spoilage, such as mould growth, off odours, or changes in texture. If you notice mould on hard cheeses like Parmesan, you can cut off the affected portion, and the rest of the cheese should still be safe to consume. However, if there are noticeable changes in colour, texture, or smell, it is advisable to closely inspect the cheese and use your judgment to determine if it is still suitable for consumption.
By following these proper storage guidelines, you can ensure that your Parmesan cheese retains its distinctive flavour and texture.

Hard, aged cheeses like Parmesan are suitable for lactose-intolerant people
Parmesan is often considered the "king of cheeses", and it's great news for those with lactose intolerance that it's an excellent option for them. Its long aging process results in a full-flavoured cheese with minimal lactose content. Lactose intolerance is a digestive condition that occurs when the body lacks the enzyme lactase, which is needed to break down lactose, a sugar found in milk, cheese, and other dairy products.
Other hard, aged cheeses that are suitable for lactose-intolerant people include cheddar, colby, Swiss, mozzarella, and Monterey Jack. These cheeses are "virtually lactose-free", with less than 1 gram of lactose per 1.5-ounce serving. Aged gouda and gruyère are also good options, as they become increasingly lactose-free with age.
While soft, creamy cheeses like ricotta, cottage cheese, and burrata contain significantly more lactose than hard cheeses, they still have far less than milk. For those with lactose intolerance, it's recommended to choose cheeses with 0 to a little over 3% lactose, which can be well-tolerated when eaten in moderation. Some examples include provolone (0-2.1% lactose), blue cheese (0-2.5% lactose), and muenster (0-1.1% lactose).

Signs of Parmesan spoilage include mould, off odours, or changes in texture
Parmesan cheese is a hard, dry cheese with a low moisture content, which makes it less susceptible to spoilage and harmful bacteria. However, it is important to be vigilant for signs of spoilage, especially if the cheese has not been refrigerated.
Changes in texture can also indicate spoilage. Parmesan is known for its hard, dry texture, so if you notice any softening or moisture accumulation on the surface, it is best to discard the cheese. Colour changes can also accompany textural alterations, and any noticeable discolouration should be inspected closely. It is important to use your judgment and consider the specific storage conditions and duration when assessing the cheese for spoilage.
While Parmesan's low moisture content and acidic pH level help to preserve it, proper storage is essential to maintaining its flavour and texture. Refrigeration is recommended to extend the cheese's lifespan, and it should be well-sealed to prevent drying out or absorbing other odours. For grated or shredded Parmesan, vacuum-sealed bags or containers with tight lids are ideal. If left at room temperature, Parmesan and other cheeses should not be kept out for more than two hours to minimise the risk of spoilage and bacterial growth.
