Cracking the Moldy Mystery: Why Does Provolone Cheese Mold Fast?

Cracking the Cheese Code: The Secret Behind Provolone’s Rapid Molding

Provolone cheese molds quickly due to its high moisture content and slightly acidic pH, making it a perfect breeding ground for mold spores. Plastic packaging can trap moisture, creating a humid environment that accelerates mold growth. Proper storage, such as keeping the cheese in a cool, well-ventilated area and airtight containers, along with regular inspection, can help prevent mold.

The Science Behind the Speed

So, let’s start by finding out what makes provolone cheese particularly susceptible to mold growth.

The number one cause is provolone’s moisture content.

It is at a much higher level than other similar types of cheese.

The excess moisture, unfortunately, is the perfect breeding ground for mold spores to thrive and multiply at an incredible rate.  

I accidentally left a piece of provolone out of the fridge, and, within a day, it was covered in furry green mold.

Not to be recommended!

Another contributing factor is the pH level of the provolone cheese. 

It is slightly more acidic than other cheeses.

Acidity also attracts mold, so combined with the moisture level, it provides an irresistible environment for the spores to make their home!

The final thing to consider is the packaging of the cheese. 

If the provolone is wrapped in plastic, this will trap the moisture and create its own humid, moist microclimate. 

This will accelerate the growth rate of the mold, turning your lovely cheese inedible in no time!

Factors at Play

Other than the actual components of the cheese that make it moldy, we also need to look at temperature, humidity, ventilation, and freshness. 

When it comes to temperature, it’s a bit like the story of Goldilocks: it should be neither too hot nor too cold!

Provolone prefers a cool environment, but not so cold that it dries out. 

On the other hand, storing the cheese in a warm place is an open invitation for mold spores! 

It can certainly be challenging to find the right balance.

Ideally, it should be refrigerated at 34°F to 38°F (1°C to 3°C).

Humidity is another factor, though obviously, this could be out of your control. 

Excessive humidity can cause a damp environment, perfect for mold growth. 

Plus, the humidity can add an extra layer of moisture to the provolone’s surface.

Ventilation is another factor, and the cheese needs proper airflow to control moisture and prevent mold. 

Don’t keep your provolone in a closed, stuffy area; keep it well-ventilated. 

And finally, probably the most obvious consideration is the freshness of the cheese.

If the provolone has already been on the supermarket shelf for some time, the mold could be well underway but not yet visible. 

Check the expiration date and try to select the freshest one possible.

Preventing the Peril

There are a few steps you can take to help prevent mold.

First, as mentioned above, keep the cheese in a refrigerator at between 34°F and 38°F (1°C to 3°C).

This is the optimal temperature to not only stop the growth of mold but also to preserve the texture and the flavor of the cheese. 

When you get your cheese home from the store, remove the original packaging and pop it in an airtight container or resealable bag. 

This creates a physical barrier against the mold spores and stops excess moisture from getting in.

You can also pat the surface of the cheese with a paper towel to remove any moisture that may have already accumulated. 

Check your provolone regularly for any hint of mold or spoilage. 

If there are any discolored patches or small suspicious-looking areas, cut them off immediately, with a generous margin around the affected piece, just in case.

If there are widespread areas of mold, you will need to discard the entire piece of cheese. 

Another tip for continuing to enjoy your provolone is to keep it away from other foods that have a strong smell. 

The cheese easily absorbs other flavors and this will affect its taste and quality.

You’ve Been Storing Cheese Wrong Your Entire Life

Key Takeaways

  • Provolone cheese molds quickly due to its high moisture content and slightly acidic pH, creating an inviting environment for mold spores to flourish. 
  • Plastic packaging, commonly used for provolone cheese, traps moisture and creates a humid microclimate, accelerating the growth of mold. 
  • Proper storage is crucial to preventing mold. 
  • Airtight containers or resealable bags are essential for storing provolone cheese, as they create a barrier against moisture and mold spores. 
  • Regularly inspect your provolone cheese for signs of mold or spoilage. 

Armed with the knowledge of why provolone cheese molds fast and preventive measures, you can now enjoy mold-free, long-lasting provolone.

Say goodbye to wasted cheese!
