Kraft advises refrigerating 4C Parmesan cheese
Parmesan cheese is a beloved condiment, enhancing the flavour of many dishes. However, the question of whether it needs to be refrigerated has sparked some debate. Kraft, a popular manufacturer of Parmesan cheese, has provided a clear recommendation for consumers.
Kraft advises that its 4C Parmesan cheese be refrigerated to maintain freshness and quality. This guidance applies specifically to the grated variety, often found in the iconic green shaker. The company suggests storing the cheese in the refrigerator at a normal temperature of 40 degrees Fahrenheit. Allowing the product to remain at room temperature should be limited to one hour, according to Kraft.
This recommendation is based on the understanding that cheese, regardless of its texture or form, is primarily a dairy product. Just as milk is typically refrigerated to prevent spoilage, so too should Parmesan cheese. While harder cheeses may be more resistant to bacterial growth due to their drier texture, refrigeration is still the optimal storage method for Kraft's 4C Parmesan cheese.
The dehydration and evaporation involved in the grating process of hard cheeses contribute to their longer shelf life at room temperature. However, refrigeration remains the preferred option to ensure maximum freshness and flavour preservation. Kraft's advice aligns with the general consensus that refrigerating grated Parmesan cheese is the best practice for food safety and quality assurance.
It is worth noting that the term "Parmesan" is not regulated in the United States, where Kraft's 4C Parmesan cheese is produced. In contrast, the term "Parmigiano-Reggiano" in the European Union specifically refers to genuine Italian Parmesan made according to strict regulations. This distinction may influence consumers' perceptions of Kraft's product as "real" Parmesan. Nevertheless, Kraft's recommendation to refrigerate its 4C Parmesan cheese remains consistent with standard food storage practices for dairy products.
In summary, Kraft advises refrigerating its 4C Parmesan cheese to optimise freshness and quality. By following this guidance, consumers can ensure that their favourite condiment remains safe and tasty for their culinary creations.

Parmesan cheese can be left out, but it may spoil
Parmesan cheese is a dry, hard cheese with a low water content, which slows the risk of the cheese going bad. This means that it can be left out of the refrigerator and will not spoil as quickly as softer cheeses. However, it should be noted that leaving Parmesan cheese out of the fridge increases the risk of contamination and spoilage.
Some people choose to leave their Parmesan cheese out of the refrigerator, especially if they plan to use it all at once. The dry texture of grated Parmesan also means that it can be left out without spoiling as quickly as fresh cheese. However, it's important to keep an eye out for mould and growth, as the fridge delays this significantly.
Kraft, for example, sells its Parmesan cheese in the unrefrigerated aisle and claims that it is safe to consume without refrigeration. They pasteurize or heat-treat their cheese to kill bacteria, and the company is confident that it is safe to eat. However, they do recommend refrigerating the cheese after opening to maintain quality and delay spoilage.
On the other hand, some people argue that refrigerating Parmesan cheese can make it too dry and affect its texture. Freezing is also an option to extend the shelf life of Parmesan cheese, especially if it is not used frequently.
Ultimately, the decision to refrigerate Parmesan cheese comes down to personal preference and the level of risk one is comfortable with. While it can be left out, proper storage in the refrigerator will help maintain its quality and delay spoilage.

Refrigeration delays mould growth
Parmesan cheese should be refrigerated to keep it fresh and preserve its quality. This is because mould can grow on cheese, and refrigeration delays mould growth.
Moulds are fungi that can grow in both indoor and outdoor environments. They favour warm, moist environments, but they can also grow in colder temperatures where moisture levels are high. Mould growth is encouraged by warm and humid conditions, and they require a relative humidity level of above 70% to establish themselves and grow. Refrigerators provide the moisture level and food sources that mould needs to grow, so it is important to keep refrigerators clean and maintain low humidity levels to prevent mould growth.
To prevent mould growth, it is important to maintain a clean environment. This includes regularly cleaning the inside of the refrigerator and other surfaces that come into contact with food, such as dishcloths, towels, sponges, and mops. It is also important to examine food well before purchasing it and to use leftovers within 3 to 4 days to reduce the chance of mould growth.
In the case of Parmesan cheese, the grating or shredding process involves dehydration and evaporation, which reduce the fat compounds in the cheese. This slows down the risk of the cheese going bad, but it is still recommended to refrigerate grated Parmesan cheese to further delay mould growth and maintain freshness.

Parmesan cheese has a long shelf life
Parmesan cheese is a hard, dry cheese with a low water content. This means that it has a long shelf life, especially when stored properly. For example, unopened Parmesan in its original packaging can last for several months beyond its expiration date. However, once the package is opened, its shelf life depends on factors such as sealing and storage conditions.
When it comes to refrigeration, opinions vary. Some sources recommend refrigerating Parmesan cheese to maintain its freshness and quality. They suggest storing it in the refrigerator at a temperature of 40°F (4°C) or lower, ensuring it is well-sealed to prevent drying out or absorbing odours. Others argue that Parmesan cheese does not require refrigeration, citing its historical use long before the invention of refrigerators. Additionally, some pre-grated Parmesan cheeses are sold unrefrigerated and are safe to consume due to pasteurization and heat treatment, which kill bacteria.
The shelf life of Parmesan cheese can be further extended through freezing, which is a viable option for those who cannot consume it quickly enough. Proper storage is crucial to maintaining the flavour and texture of Parmesan cheese. When stored at room temperature, Parmesan, like other hard cheeses, should not be left out for more than two hours.
It is worth noting that the shelf life of grated or shredded Parmesan may be shorter compared to a block or wheel of Parmesan. This is because the reduction of fat compounds through the grating or shredding process slows down the risk of the cheese spoiling. However, once mould is present in grated cheese, the entire container is considered suspect.

Parmesan cheese can be frozen
Parmesan cheese is a hard cheese with a long shelf life if properly stored. While refrigeration is recommended to preserve the quality and freshness of the cheese, it can also be frozen.
Freezing Parmesan cheese is a great option to prolong its shelf life. To freeze Parmesan cheese, it is important to first wrap the cheese to prevent moisture from causing spoilage. Wrapping the cheese also helps to prevent condensation and ensures the cheese can breathe. You can use parchment paper, cheesecloth, cheese paper, or wax paper to wrap a wedge of Parmesan cheese. Alternatively, grated Parmesan cheese should be stored in an airtight container to maintain freshness and prevent spoilage.
Once the cheese is wrapped or stored in an airtight container, it can be placed in the freezer. Freezing Parmesan cheese is a convenient way to store it for a longer period, especially if you have a large quantity or won't be using it frequently. Freezing will help to maintain the quality and flavor of the cheese.
When you are ready to use the frozen Parmesan cheese, simply remove it from the freezer and let it thaw gradually in the refrigerator. This will ensure that the cheese returns to a suitable temperature and texture for consumption. It is important to note that freezing may affect the texture and taste of the cheese to some degree, but it still provides an extended storage option for Parmesan cheese.
By following these steps, you can effectively freeze and store Parmesan cheese, ensuring that you always have this flavorful ingredient on hand for your culinary creations.
