If you’ve ever consumed a piece of parmesan cheese showing signs of mold, or struggled to scoop out the final bit from a jar, you are already familiar with the experience of attempting to eat food that’s past its peak freshness date.
While many people are familiar with the idea that food goes bad after a certain amount of time, most aren’t aware of how quickly or how much they should consume before throwing away any spoiled foods.
So, in this article, we’ll talk about how long parmesan cheese lasts, whether it needs to be kept cold, if you can freeze it, and how to tell if you have some bad parmesan cheese at home.
How long does parmesan cheese last?
You’re probably wondering how long parmesan cheese lasts.
The short answer is that it depends on where you live and how well you store it.
Some parmesan cheeses will last longer than others.
For example, a lot of people keep their parmesan cheese in the refrigerator, but there are other factors to consider.
If you want your parmesan to last as long as possible, you need to make sure it isn’t exposed to too much moisture or heat.
In addition, you also need to take into account the type of cheese you have.
For instance, while regular parmesan might last a few months, good quality aged versions can last up to two years.
As another example, you may want to consider storing your cheese in an airtight container.
This way, you can prevent oxygen from entering the container, which will help preserve the cheese.
However, you shouldn’t use plastic containers because they allow more oxygen to enter the container, which will cause the cheese to spoil faster.
The best way to ensure that your parmesan won’t go bad is by using a vacuum sealer.
These machines suck all the air out of the container, so your cheese will stay fresh for a very long time.
Another important factor to consider when it comes to keeping parmesan cheese fresh is humidity.
If you live somewhere humid, you’ll want to avoid exposing your cheese to too much humidity.
Otherwise, it could lead to mold growth.
Also, you don’t want to leave your parmesan cheese sitting in direct sunlight.
It will dry out, which will result in it going bad faster.
If you do decide to purchase a vacuum sealer, you can find them online for under $100.
They come in handy for lots of different uses, including preserving food and making homemade ice cream.
Does parmesan cheese need to be refrigerated?
Parmesan cheese is one of those cheeses that doesn’t really need to be refrigerated.
In fact, it’s not uncommon for people to buy parmesan cheese in bulk and keep it on their kitchen counter instead of in the fridge.
However, there are a few things you should remember when storing parmesan cheese:
- It tastes better when it’s fresh.
- The longer it stays in its original packaging, the more likely it is to go bad.
- It can also be dangerous to store parmesan cheese in the refrigerator because of the bacteria that can grow on the surface of the cheese. This could make you sick if you eat it.
- Because of all these reasons, it’s best to keep parmesan cheese in an airtight container, preferably in its original box, so that you don’t risk exposure to harmful bacteria.
Why Parmesan Cheese Doesn’t Need Refrigeration
As mentioned above, parmesan cheese doesn’t need to be kept in the fridge because it doesn’t contain live cultures.
These live cultures help prevent the growth of harmful bacteria, which is why you always see them listed as ingredients on packaged foods.
But parmesan cheese isn’t made from these cultures.
This means that you don’t need to worry about the parmesan cheese going rancid or developing an unpleasant odor.
Because of this, it can be left out on the counter without worrying about it spoiling.
Also, parmesan cheese contains salt, which helps preserve it.
While salted foods do start to go bad after a while, parmesan cheese usually lasts for several months even when exposed to high temperatures.
Can parmesan cheese be frozen?
Parmesan cheese is made from cow’s milk, which means it contains fat, so it won’t freeze solid.
The texture will stay the same as long as it isn’t exposed to extreme temperatures.
However, because parmesan cheese is high in moisture content, it can easily become waterlogged.
This means that if you keep it in an airtight container, it may not freeze completely.
If you do want to freeze some parmesan cheese, make sure you wrap it tightly to prevent water from seeping in and causing it to go soft.
When it comes to storing cheese in the freezer, there are two main ways you can choose to do it.
You can either buy a freezer bag specifically designed for freezing cheese, or you can use a ziploc bag along with a piece of aluminum foil.
You can also add ice packs to your bag to help keep the cheese cool while it freezes.
Be careful not to pack too many ice packs, though, or else you could end up with a big chunk of ice inside your bag that will melt into your cheese.
If you don’t want to freeze your parmesan cheese, you can still enjoy it by keeping it in the fridge.
Just remember to remove it from the fridge at least 30 minutes before eating it to let it come back to room temperature.
What does parmesan cheese taste like?
Parmesan cheese comes from Italy, where it’s been produced since the late 19th century.
It’s typically made by grinding up whole raw cow’s milk into a creamy paste, adding salt and other ingredients, and letting the mixture sit until it’s aged for several months.
The longer the cheese ages, the more flavorful it becomes.
So, while there are many different types of parmesan cheeses out there, all of them are made using the same basic process.
When you buy a block of parmesan cheese, you’re probably going to want to use it as soon as possible.
After all, the longer you leave it sitting around, the less flavor it has.
But even though most parmesan cheeses need to be consumed within six months, there are plenty of exceptions.
For example, if you purchase a large block of parmesan, you might be able to keep it in your fridge for several years without worrying about it spoiling.
In fact, if you’ve ever purchased a large block of parmesan cheese, chances are good that you’ll find it in the back of the refrigerator or in the freezer section of your local grocery store.
However, if you don’t use it right away, you could end up wasting a lot of money on an expensive product that you can’t enjoy.
As such, it’s important to understand how long parmesan cheese lasts so that you can make sure to use it before it starts to go bad.
How long does parmesan cheese last?
Because parmesan cheese contains live cultures, it doesn’t spoil quite the way regular cheese would, but it still isn’t good to eat once it starts to go bad.
According to the USDA, fresh parmesan cheese can last for up to two years in the refrigerator, although it may not retain nearly as much flavor as it did when it was first packaged.
For example, if you bought a block of parmesan cheese in January, you might be able to use it through July, but after that, you might only be able to eat it through November.
This is because the bacteria that makes parmesan cheese so tasty also produces lactic acid, which causes the cheese to become harder over time.
Of course, this is just one example.
If you buy a block of parmesan cheese in May, you might be able to use it through October, but after that, you could run into issues.
It’s best to purchase your parmesan cheese directly from the manufacturer whenever possible.
Since they know exactly how long they plan to sell their products for, it’s likely that you’ll be able to use it within the first year or two after you buy it.
How is parmesan cheese made?
Parmesan cheese is actually made from three different types of cheeses: Emmental, Romano, and Grana Padano.
The first two are cow’s milk cheeses, while the third is a sheep’s milk cheese.
The cheeses are aged for up to 12 months, which allows them to develop their distinctive flavors.
The longer the aging process, the more complex the flavor becomes.
During the aging process, the cheeses undergo a series of transformations that change the way they taste and feel.
For example, the moisture content gradually decreases, the fat content increases, and the protein content increases as well.
This means that the cheese gets harder and less sticky.
After the aging period, the cheeses are cut into blocks and packaged in either plastic or glass containers.
They are also sometimes coated with wax to keep them from drying out.
How long does parmesan cheese last?
According to the United States Department of Agriculture (USDA), parmesan cheese can last for up to one year if it is stored properly.
If it isn’t refrigerated, the cheese will begin to deteriorate within just a few weeks.
For instance, if you buy a block of parmesan cheese that’s been sitting on a shelf for several days, the texture might be mushier than usual.
In addition, the smell could be overpowering because of the bacteria that’s present.
However, if you bring the cheese back to room temperature, it will eventually start to soften and go bad.
In fact, according to the USDA, parmesan cheese loses 50 percent of its nutritional value after five days at room temperature.
In order to extend the longevity of your cheese, you need to keep it in the fridge.
When you put parmesan cheese in the refrigerator, it will remain edible for up to six months.
But, even if you don’t use it right away, it’s best to keep it cold so that it doesn’t dry out.
You can also freeze parmesan cheese for future use.
Just make sure that you wrap the frozen cheese tightly in foil or plastic bags so that it won’t thaw too fast.
This method works well for storing parmesan cheese for up to six months, but there are other ways to preserve it without freezing it.
How to tell if parmesan cheese has gone bad
There are various signs that indicate that your parmesan cheese has gone bad.
One of the most obvious ones is when you see white patches on the surface of the cheese.
These spots are usually caused by mold spores, which are microscopic organisms that grow on the cheese.
These spores cause the cheese to become soft and runny, and the cheese may even start to smell sour.
As soon as you notice these signs, you should throw the cheese away.
Another sign that your parmesan cheese has gone bad is when you find a large number of small holes in your cheese.
These holes can be anywhere between 1/16th and 1/8th of an inch in size.
And, they can appear on any part of the cheese.
When you look closer at these holes, you’ll discover that they are almost always circular.
They can also be yellowish in color due to the presence of sulfur compounds.
And, finally, another sign that your parmesan cheese has gone bad is when you can no longer remove it from the container.
Since the cheese contains fats and proteins, it’s very difficult to remove it from the packaging.
So, if you want to save it, you’ll need to buy new containers.
How do you store parmesan cheese?
Parmesan cheese is one of the best cheeses for keeping for a long time because it contains a lot of salt, which helps preserve it.
However, there are other factors that can affect how long parmesan cheese lasts, including humidity levels and temperature.
In general, the older the cheese gets, the more likely it is to go bad.
This is because as the cheese ages, the enzymes begin to break down the proteins inside the cheese, causing them to dry up and eventually turn rancid.
The moisture inside the cheese also evaporates, leaving behind a layer of fat on top.
This makes the cheese harder and drier than it once was.
As a result, the only way to keep parmesan cheese from going bad is to keep it cool and dry.
At room temperature, parmesan cheese starts to spoil within three months.
At refrigerator temperatures, however, it can last for years.
Because of this, it’s important to buy parmesan cheese that’s been refrigerated well so that it doesn’t go bad too fast.
You can also extend the life of parmesan cheese by freezing it.
It’s best to freeze it right after you open it so that it keeps its texture and freshness.
And even though it may not look like it, it’s still safe to eat parmesan cheese that has turned brown or black.
The color change isn’t necessarily a sign that the cheese is toxic or dangerous, but it does indicate that it’s no longer fit for consumption.
Can you eat Parmesan past its use by date?
Parmesan cheese is considered an aged product, which means that it has been allowed to sit for a while so that it can develop flavors and aromas from being exposed to air.
The exact amount of time varies depending on the brand, but generally speaking, parmesan cheese won’t go bad until it starts to taste sour or bitter.
It also doesn’t need to be refrigerated, as it will keep well without it for up to a year.
However, once the cheese starts to turn rancid, it becomes very difficult to remove all of the unpleasant odors and flavors from the surface.
At this point, it’s best to throw the cheese away, even though it may not actually be completely ruined yet.
The only thing left to do is to decide whether you want to eat the rest of it.
If you think you might regret eating it, consider tossing it out immediately.
Otherwise, you can give it a few more days and see if you still feel like eating it—but don’t leave it around for too long because it could spoil faster than you expect.
What does bad Parmesan cheese smell like?
When the parmesan cheese starts losing its flavor, it becomes harder, and starts to take on an unpleasant odor.
This smell is similar to the smell of rotting meat, which is why it’s so common to find parmesan cheese in grocery stores that smells awful.
The problem is that the smell doesn’t just come from the parmesan itself – it comes from the bacteria that grows inside the cheese, too.
The bacteria that causes the smell is called Enterobacter cloacae, and while it typically lives in soil and water, it can also grow inside dairy products such as milk and cheese.
When the bacteria gets into the cheese, it can cause the texture to change, and the smell to increase.
Some people think that the smell is caused by the moisture in the cheese, but this isn’t true.
Enterobacter cloacae can live in dry environments, so even though the parmesan may appear dry, it still contains enough moisture to support the growth of the bacteria.
As the bacteria continues to multiply, the texture of the cheese changes, and it begins to taste sour and bitter.
Once the bacteria reaches a high enough concentration, it can make the cheese very difficult to remove from the container.
Does parmesan cheese smell like puke?
Before answering the question of when parmesan cheese starts to go bad, let’s answer another question: Do you think that parmesan cheese smells like puke?
The short answer is no, but there is an odor associated with parmesan cheese that isn’t pleasant.
The odor comes from the bacteria that grows on the surface of the cheese.
In fact, this is why you should always use fresh parmesan cheese instead of pre-shredded or grated parmesan cheese.
If the cheese is old, it may not contain as much moisture, which means that the bacteria would have more room to grow.
This also explains why parmesan cheese doesn’t taste good once it gets past a certain age.
As the bacteria begin to multiply, the cheese becomes less flavorful and begins to break down.
This is why it’s important to keep your parmesan cheese refrigerated so that the bacteria don’t have a chance to grow.
In addition, parmesan cheese contains lactic acid, which gives it its tangy flavor.
But as the lactic acid decreases, the cheese loses its flavor.
So, if you want to enjoy parmesan cheese for as long as possible, make sure to buy fresh parmesan cheese and store it in the fridge.
How long do parmesan cheeses last?
If you’re wondering how long parmesan cheese lasts, the average lifespan of parmesan cheese is around two years.
That said, parmesan cheese can last even longer if it’s stored correctly.
In fact, some experts say that parmesan cheese can last up to five years if it’s stored properly.
However, this depends on where you live.
While parmesan cheese can last for five years in a cool, dry place, it can only last three months in a warm, humid location.
So, if you live somewhere with high humidity, you might want to consider buying smaller containers of parmesan cheese rather than one large container.
This way, you won’t need to worry about wasting leftover cheese if you end up eating all of it.
As mentioned above, the main reason parmesan cheese goes bad is because of the bacteria that grows on the surface.
To prevent this from happening, you should never leave your parmesan cheese out on the countertop.
Instead, you should store it in the refrigerator or in a cool cabinet.
You should also avoid letting your parmesan cheese come into contact with other foods, such as bread or pasta, as these can contaminate the cheese.
When storing parmesan cheese in the fridge, wrap it tightly in plastic wrap or aluminum foil to ensure that it stays cold.
And while it’s tempting to cover it with plastic wrap, remember that this can trap the moisture inside the cheese, which makes it harder to remove later.
It’s also a good idea to check the expiration date on your parmesan cheese.
When shopping for parmesan cheese, look for labels that indicate “best by” dates, which are usually three to six months after the package was opened.
This ensures that you’re purchasing fresh parmesan cheese and avoiding any issues with spoilage.
