Shredded Parmesan Cheese: How Long Can You Keep It?

Parmesan cheese is a staple in kitchens around the world, but how long does shredded parmesan cheese last? When stored correctly, an unopened package of shredded parmesan cheese can last for 7 to 9 months in the refrigerator. However, once the package is opened, it is best to consume the cheese within 3 to 7 days for optimal quality. To extend the shelf life, shredded parmesan can be frozen and will maintain its best quality for about 8 months.

Refrigerated shredded parmesan lasts 5-7 days

To maximise the shelf life of shredded parmesan, it should be stored in the refrigerator at all times, in tightly sealed original packaging or placed in resealable plastic bags or airtight containers. If you want to extend its shelf life even further, you can freeze it.

When it comes to determining whether your shredded parmesan has gone bad, the best way is to examine its smell, appearance, and texture. If the cheese has developed an off odour, flavour, or appearance, it should be discarded. If there is mould, discard all of the shredded parmesan cheese.

Unopened, it can last 7-9 months

Parmesan cheese is a hard cheese with a low moisture content, which means it has a long shelf life. If stored unopened in the fridge, shredded parmesan cheese can last for 7 to 9 months. This is because the cheese is sealed and therefore protected from the elements, such as heat and moisture, which can cause spoilage.

The length of time that shredded parmesan cheese can be left unopened and unused is dependent on the "best before" or "use by" date on the packaging. It is safe to assume that the cheese will be edible for a few weeks after the date on the packaging, but it is always important to check for signs of spoilage before consuming.

To ensure that your shredded parmesan cheese lasts as long as possible, it is important to store it correctly. This means keeping it in the fridge, in an airtight container, or in its original packaging, which should be tightly sealed.

It is also important to note that the shelf life of shredded parmesan cheese is shorter than that of a block of parmesan cheese. This is because, once shredded, the cheese has a larger surface area, which is more susceptible to bacterial growth.

Freezing shredded parmesan is a good way to extend its shelf life

Parmesan cheese is a hard cheese with a long shelf life. However, once shredded, its quality degrades faster. Shredded parmesan will only last a few days in the fridge, so freezing is a good way to extend its shelf life.

Shredded parmesan can be frozen for up to a year. It is best to seal the cheese in an airtight container or a tightly sealed bag and then place it in the freezer. If freezing for longer than 2 months, it is recommended to place the package inside a heavy-duty freezer bag to prevent freezer burn.

When using frozen shredded parmesan, it is not necessary to thaw it first. It can be added directly to dishes such as pasta, soups, or stews. The cheese will thaw almost instantly when sprinkled on hot food.

Freezing shredded parmesan is a convenient way to ensure that you always have this tasty, versatile cheese on hand without having to worry about it going bad.

Signs of spoilage include a change in colour and texture

Shredded parmesan cheese is a convenient way to add flavour to pasta, salads, and soups. However, it is important to monitor this cheese for any signs of spoilage as it has a shorter shelf life than blocks of parmesan.

Shredded parmesan cheese is susceptible to bacterial growth due to its increased surface area. This means that it can quickly develop signs of spoilage, and it is important to inspect both the colour and texture of the cheese before consuming it.

One of the most obvious signs of spoilage is the presence of mould. If you see any patches of blue or green mould, the entire package should be discarded for safety reasons. Mould spores can quickly spread throughout the cheese, even if you cannot see them, so it is not advisable to try and salvage the product by picking out the mouldy pieces.

In addition to mould, the colour of the cheese may change as it deteriorates. Fresh parmesan has a pale, almost white or very light yellow colour. As it ages, it can turn darker and more orange. This change in colour is a sign that the cheese is no longer safe to eat.

Another sign of spoilage is a change in texture. Freshly grated parmesan should feel dry to the touch and flow freely. If the cheese feels wet or spongy, or if it starts to clump together, it is likely to be spoiled and should be discarded.

To prolong the shelf life of shredded parmesan cheese, it is important to store it properly. It should be kept in an airtight container or tightly sealed packaging in the refrigerator. By preventing exposure to moisture and heat, you can help to reduce the risk of spoilage and maintain the quality and flavour of the cheese.

It's best to store it in an airtight container

Shredded parmesan cheese is best stored in an airtight container. This is because, when the cheese is grated, it exposes more of its surface area, giving bacteria more opportunities to grow. Storing it in an airtight container will help to prevent this.

When storing shredded parmesan, it is also important to ensure that the container is sealed tightly. This is another way to prevent bacteria from growing on the cheese.

In addition to using an airtight container, you should also keep shredded parmesan in the fridge at all times. This will help to prolong its shelf life.

If you want to extend the shelf life of shredded parmesan even further, you can freeze it. Frozen parmesan can maintain its best quality for about 8 months but will remain safe to eat indefinitely. However, freezing may affect the texture and flavour of the cheese. It is therefore best used in cooked dishes, such as sauces, soups, and casseroles.

Finally, it is important to always use clean utensils when scooping shredded parmesan cheese. This will help to prevent microbial contamination.
