Parmesan cheese is a versatile ingredient that adds flavor and depth to many dishes. But how do you know if it’s gone bad? How long does Parmesan cheese last in the fridge? And what should you do when it has expired?
This guide will answer all your questions about expired Parmesan cheese, from how to tell if it has expired to what happens if you eat slightly moldy Parmesan. By the end of this article, you’ll know everything you need to know about storing Parmesan cheese for maximum flavor and safety.
Is Grated Parmesan Cheese Good After Expiration Date?
When it comes to grated parmesan cheese, the expiration date doesn’t always reflect the quality of the product. Although it’s past its best before date, you can still use it safely and reap many benefits.
The freshness of the cheese is determined by how quickly moisture has been removed from the cheese. Since grated Parmesan cheese has already had most of the moisture removed, it’s able to last longer than other types of cheese.
When making dishes like pasta or salads, grated Parmesan cheese adds creaminess and flavour. To tell if it’s still good, look for discoloration or a strong scent from the container – these are the first signs of degradation.
- Grated Parmesan cheese can last longer than its stamped date
- Look for signs of discoloration or strong scent when checking for freshness
- A sprinkle of grated Parmesan will add flavour and creaminess to pasta and salads
Safety Check: Eating Expired Parmesan Cheese
Parmesan is a long-lasting cheese that can last up to 9 months if unopened. The label will often include a “use-by” or “best if used by” date, allowing you to know the freshest possible date in which to enjoy the cheese.
But what if the expiration date has passed? Is it still safe to eat?
Generally speaking, you should be able to consume parmesan up to a few weeks past its expiration date. By then, however, expect that the quality of taste and texture may have changed from when it was first purchased. It’s also worth noting that this applies for more hard cheeses like parmesan, but for softer cheeses such as brie, a few days past expiration is much too long.
If you can still detect strong odors from the cheese, or any mold forming on it, this should be an indication that the cheese has spoiled and should no longer be consumed.
Some ways you can be sure parmesan is good for consumption is by:
- Checking for a slimy surface
- Smelling it (it should still have a distinct smell even when past its expiration date if it’s still good)
- Tasting it (small amounts can be consumed)
It should also note that if you’re ever in doubt about how good the cheese is, simply throw it out! Eating expired cheeses may cause food poisoning or other health-related issues. So above all else, safety should come first.
Know Your Limits: How to Tell if Your Parmesan is Spoiled
It can be difficult to tell when Parmesan cheese has gone bad, but there are a few signs that can alert you to its condition. Here are the indicators that Parmesan cheese is past its best before date:
- The texture of the cheese will become hard.
- It darkens in color.
- It emits a strong smell.
- White, blue or green mold may appear on the surface.
If any of these signs are present, it’s best not to consume the Parmesan cheese. If you discover mold on a chunk of Parmesan cheese, do not scrape it off and consume the rest of the block.
There are a few steps to take to make sure the mold does not spread.:
- First, separate any chunks with visible mold from the remaining blocks and dispose of them.
- Secondly, scrape off any residual pieces of mold that may have spread onto other chunks using either a butter knife (for softer cheeses) or a vegetable peeler (for hard cheeses).
- Finally, cleanse all surfaces that have come into contact with the cheese with hot water and soap.
In order to ensure your health and safety when consuming perishable food like Parmesan cheese, check each block before using. Pay close attention to their color, smell and texture to determine whether they are still good or should be thrown out. By following these guidelines, you can help prevent illness from consuming expired foods and enjoy your homemade dishes with peace of mind!
The Long and Short of Storing Parmesan in the Fridge
Unopened blocks of Parmesan cheese can be stored in your refrigerator for seven to nine months. This is because the low temperatures make it more challenging for bacteria and mold to grow. If you open your block of Parmesan cheese, however, it won’t last as long — a maximum of two months.
Grated Parmesan cheese is already exposed to air, so it must be consumed much more quickly than the unopened blocks. Grated Parmesan cheese will typically last up to one week when kept in the refrigerator.
If you notice that your Parmesan cheese has turned yellow or has started to get moldy, it’s likely spoiled and should be thrown out. Here are some tips for keeping your Parmesan cheese fresh:
- Keep unopened blocks of Parmesan properly sealed.
- Refrigerate once opened.
- Group leftovers together in an airtight container.
- Consume grated cheese within a week.
- Check for signs of spoilage before consuming.
Overall, with proper storage and care for your Parmesan cheese, it should last anywhere from one week to nine months depending on if it’s been opened or not! In order to extend its shelf life for as long as possible, make sure you properly seal and refrigerate your Parmesan cheese.
Molds and Minds: The Dangers of Eating Slightly Moldy Parmesan
Mold can be scary – even the sight of it can turn our stomachs! If you spot mold on a block of hard or semisoft cheese, like parmesan, it is best to discard the entire block. However, if you notice the beginnings of mold growth, there is a safe way to salvage the rest of your cheese.
It is safest to cut off the visibly contaminated area with a one-inch radius surrounding it. This ensures that no trace of mold is left on the cheese. Even though it may be tempting to just scrape away the mold, this could be counterproductive as some spores could still remain in the cheese.
So what happens if you do accidentally consume some moldy parmesan? Although rare, possible symptoms can include:
- Shortness of breath
- Allergic reactions
If you experience any of these symptoms after consuming minorly contaminated cheese, seek medical attention immediately.
Although eating slightly moldy cheese might not do much harm, it is not recommended.
Depending on the type of cheese, its storage conditions and length of time exposed to mold spores, consuming slightly contaminated cheese may cause few adverse effects. To play it safe and avoid potential health risks, always throw out visibly moldy cheese and don’t come near it!
